   Opinion

MÁRQUEZ, J.

After a high school football game on September 23, 2011, head coach Rafael Ward, and several other coaches, were accompanying their families to their cars for their protection because of a threat by defendant Ronald Henderson Turner, a parent of one of the players. Defendant had called one of the coaches a racial slur and then said, “I’ll see you after the game.” Coach Ward told Lawrence Fenton, an off-duty probation officer providing security at the game, about the threat and that defendant had said he was going to carry out his threat after the game. A short time later, Ward told Officer Fenton that he (Ward) had learned from his aunt (who had heard it from an acquaintance of defendant’s) that defendant “had a gun on him.” Officer Fenton called Salinas police for backup. His partner who was with him, Steve Hinze (also an off-duty probation officer), located defendant and (with the police) detained him at or next to the parking lot outside the stadium. Defendant was handcuffed at gunpoint while officers determined whether he was armed. After admitting to a police officer that he had a gun, the police located a loaded revolver concealed on his person, and he was arrested.

After the denial of defendant’s motion to suppress evidence pursuant to Penal Code section 1538.5, he pleaded no contest to possession of a firearm in a school zone. The court suspended defendant’s sentence and placed him on felony probation under various terms and conditions, including the condition that he serve 250 days in county jail.

Defendant challenges the court’s denial of his suppression motion. He asserts that the officers based their conclusion that he was armed on unsubstantiated hearsay from an unknown source, and that this was, in essence, the kind of anonymous tip that the United States Supreme Court held in Florida v. J. L. (2000) 529 U.S. 266 [146 L.Ed.2d 254, 120 S.Ct. 1375] (J.L.) could not support an investigative stop. He makes several arguments, including (1) he was subjected to a de facto arrest without the officers’ having probable cause at the time to believe he had committed a crime and (2) even if there were no arrest, his detention was unjustified because the officers had no specific articulable facts to reasonably suspect that he was involved in illegal activity.

We conclude in the published portion of this opinion that the suppression motion was properly denied. Based upon the totality of the circumstances, (1) the officers’ actions to determine whether defendant was armed were reasonably necessary for their protection and did not result in his de facto arrest and (2) the officers had sufficient articulable facts to support their reasonable suspicion that defendant had committed a felony—namely, possession of a firearm in a school zone. Therefore, the investigative stop was constitutionally permissible. In the unpublished portion of this opinion, we reject defendant’s claim for additional conduct credits under the latest amendment to section 4019, but agree that defendant’s challenge to two probation conditions (involving possession and consumption of drugs and alcohol, and possession of firearms) has merit. Accordingly, we will order the probation conditions modified to include a requirement of defendant’s actual knowledge of the possession and/or use of the specified items. We will affirm the order of probation as modified.

FACTS

A football game at Everett Alvarez High School in Salinas took place on the evening of September 23, 2011, between approximately 7:00 or 7:30 and 10:15 p.m. Rafael Ward and Anthony Stewart were two of the coaches on the team for which defendant’s son played. Ward testified that “there was a negative vibe [among the crowd] in general” during the game. Near halftime, one of the players had his leg broken, and the “negative vibe” became more intense. At one point, defendant approached Ward on the field while he was talking to defendant’s son. At that moment, defendant’s son was angry and very upset with another coach. Defendant told Ward, “ ‘Coach, I was the one that told him to take a knee.’ ” Ward and defendant shook hands as defendant left the field; defendant did not threaten Ward. But Stewart told Ward that defendant had threatened him (Stewart). Stewart was upset and said that defendant “called him a ‘bitch-ass [racial slur.] I’ll see you after the game.’ ”

When the game concluded, a number of coaches walked their families to their cars because of security concerns. According to Ward, people in the crowd “came up to Coach Stewart and said, ‘Hey, they said they’re going to wait for you in the parking lot.’ ” Ward assumed that “ ‘they’ ’’ referred to defendant, who had threatened Stewart earlier.

As Ward was walking out of the stadium, his aunt, Annie Camel, approached him. She asked, “ ‘Hey, Ralph, what is going on with you and Spanky [defendant]?’ ” Because his aunt was “obviously worried,” Ward tried to dispel her concern. Camel then told Ward: “ ‘Well, I’m just telling you [that] you need to be careful because I heard he had a gun,’ or T heard he has a gun.’ ” She said that her friend, Jeannette Smith, “ ‘said he has a gun.’ ” The school principal, Darrin Herschberger, was nearby and overheard Ward and Camel. Herschberger asked Ward to clarify who it was who had a gun, and Ward responded that they were referring to defendant.

Monterey County Probation Officers Fenton and Hinze were hired by the high school to provide additional security at the football game. (They wore shirts with badges and carried service weapons.) After the game, Herschberger instructed Officer Fenton to go to the parking lot with Officer Hinze because one or more people in the crowd had threatened one of the coaches. While Officers Fenton and Hinze were together in the parking lot, Officer Fenton spoke to Ward. Officer Fenton testified that he “asked [Ward] . . . what was going on. He told me that a parent had come up to them during the game because he was upset about something that one of the coaches had said or done and threatened [‘]to take care of it on the outs[’] is the way it was said to me. At which point that’s why the coaches had come out because they were concerned about their families getting hurt.” Ward told Officer Fenton that the parent who had made the threat was the father of one of the players, Turner. Ward walked off and then came back and told Officer Fenton that “he had heard [that defendant] had a gun on him.” Officer Fenton asked Ward how he knew this; Ward responded that “his aunt knew someone who knew [defendant] and said he had a gun on him.”

Officer Fenton, in Officer Hinze’s presence, then called the Salinas Police Department, indicating “that we had received a report of a person at the school with a gun” and requested “additional units to . . . provide cover and let us contact that person safely.” Officer Fenton also obtained a description of defendant from a school official.

Officer Hinze testified that he had been with Officer Fenton and Principal Herschberger in the parking lot after the game; Officer Hinze was “about an arm’s[-]length away or less” from Officer Fenton during this time. Officer Hinze described the situation of the crowd moving to get to their cars as “a little bit more chaotic than usual.” Officer Fenton told him that there had been an incident during the game when a player was injured; there was “a possible threat”; and someone might have a gun. Officer Hinze did not know the specifics of the threat, only that “[i]t was something [that] was going to be taken care of in the parking lot . . . .” Officer Hinze was provided with defendant’s name as the person potentially having a gun; a school supervisor then radioed a physical description of defendant to the officer.

Officer Hinze observed six or seven people, including defendant, near a dumpster at the edge of the parking lot near the comer of Nantucket and Independence Streets. The officers had encountered this same group in the same location before the game. They were “standing ... off to the side looking a little intimidating,” and the coaches were escorting their families to the vicinity of the group. There were beer cans next to the group and “there was concern that this [was] supposedly the group that might [have made] a threat . . . .” Approximately one minute after the arrival of the first marked police car in the parking lot, and as Officer Hinze received a physical description of defendant over the radio, he observed defendant—from a distance of about 45 feet—break away from the group and walk off campus.

Officer Hinze then shone his flashlight on defendant, identified himself as “ ‘Probation,’ ” drew his service weapon, and directed defendant to put up his hands. Officer Jordan White arrived—having responded to a police dispatch indicating that there was a man with a gun at the Everett Alvarez High School football game—and ordered defendant to the ground. Another police officer held defendant at gunpoint while Officer White approached and handcuffed him. Officer White asked defendant if he was carrying any weapons; defendant responded that he had a gun in his front pocket. Officer White reached into defendant’s pocket and recovered a black short-barrel revolver that was loaded.

PROCEDURAL BACKGROUND

In an information filed November 9, 2011, defendant was charged with three felonies, namely, possession of a firearm in a school zone (§ 626.9, subd. (b); count 1); carrying a loaded, unregistered firearm (former § 12031, subd. (a)(1); count 2); and carrying a concealed firearm (former § 12025, subd. (a)(2); count 3). It was also alleged as an enhancement to count 1 that possession of a firearm in or on the grounds of a public or private school (K-12) is punishable by imprisonment of two, three, or five years (§ 626.9, subd. (f)(1)). It was alleged further as enhancements to count 2 (former § 12031, subd. (a)(2)(F)) and count 3 (former § 12025, subd. (b)(6)) that defendant was not the registered owner of the firearm.

Defendant thereafter filed a motion to suppress evidence pursuant to section 1538.5, arguing that the property seized (i.e., the black revolver) should be suppressed because it was the product of an unlawful search and seizure. The motion was opposed by the People. After the presentation of evidence and argument on January 5 and 6, 2012, the court denied the suppression motion. Immediately after the court’s ruling, defendant withdrew his not guilty plea, and entered a plea of no contest to count 1, conditioned upon the dismissal of the remaining counts and his receiving felony probation. The court thereafter suspended imposition of sentence and granted defendant probation for three years on various terms and conditions, including the condition that he serve 250 days in the county jail with the court awarding him 130 days of custody credits and 64 days of conduct credits for a total of 194 presentence credits. Defendant filed a timely notice of appeal.

DISCUSSION

I. Motion to Suppress

A. Standard of Review

“An appellate court’s review of a trial court’s ruling on a motion to suppress is governed by well-settled principles. [Citations.] [¶] In ruling on such a motion, the trial court (1) finds the historical facts, (2) selects the applicable rule of law, and (3) applies the latter to the former to determine whether the rule of law as applied to the established facts is or is not violated. [Citations.] ‘The [trial] court’s resolution of each of these inquiries is, of course, subject to appellate review.’ [Citations.] [¶] The court’s resolution of the first inquiry, which involves questions of fact, is reviewed under the deferential substantial-evidence standard. [Citations.] Its decision on the second, which is a pure question of law, is scrutinized under the standard of independent review. [Citations.] Finally, its ruling on the third, which is a mixed fact-law question that is however predominantly one of law, ... is also subject to independent review.” (People v. Williams (1988) 45 Cal.3d 1268, 1301 [248 Cal.Rptr. 834, 756 P.2d 221]; see People v. Ayala (2000) 23 Cal.4th 225, 255 [96 Cal.Rptr.2d 682, 1 P.3d 3].)

In reviewing the denial of a motion to suppress, we examine “the record in the light most favorable to the trial court’s ruling.” (People v. Jenkins (2000) 22 Cal.4th 900, 969 [95 Cal.Rptr.2d 377, 997 P.2d 1044].) All presumptions favor the trial court’s exercise of its power to judge.the credibility of the witnesses, resolve any conflicts in the testimony, weigh the evidence, and draw factual inferences, “ ‘and the trial court’s findings on such matters, whether express or implied, must be upheld if they are supported by substantial evidence.’ ” (People v. Leyba (1981) 29 Cal.3d 591, 596-597 [174 Cal.Rptr. 867, 629 P.2d 961], quoting People v. Lawler (1973) 9 Cal.3d 156, 160 [107 Cal.Rptr. 13, 507 P.2d 621]; see In re Lennies H. (2005) 126 Cal.App.4th 1232, 1236 [25 Cal.Rptr.3d 13].) Where there is no controversy concerning the underlying facts—as is the case here—our task is simplified: The only issue is whether that rule of law, as applied to the undisputed historical facts, was or was not violated. This is an issue for our independent review. (See People v. Thompson (2006) 38 Cal.4th 811, 818 [43 Cal.Rptr.3d 750, 135 P.3d 3].)

B. Detentions Under the Fourth Amendment

The legal basis upon which a peace officer may detain a citizen has been explained as follows: “[I]n order to justify an investigative stop or detention the circumstances known or apparent to the officer must include specific and articulable facts causing him to suspect that (1) some activity relating to crime has taken place or is occurring or about to occur, and (2) the person he intends to stop or detain is involved in that activity.” (In re Tony C. (1978) 21 Cal.3d 888, 893 [148 Cal.Rptr. 366, 582 P.2d 957], superseded on other grounds in Cal. Const., art. I, § 28,) “The corollary to this rule, of course, is that an investigative stop or detention predicated on mere curiosity, rumor, or hunch is unlawful, even though the officer may be acting in complete good faith. [Citation.]” (In re Tony C., at p. 893, citing Terry v. Ohio (1968) 392 U.S. 1, 22 [20 L.Ed.2d 889, 88 S.Ct. 1868] (Terry).) The fact that there exists “[t]he possibility of an innocent explanation [for the suspect’s activity] does not deprive the officer of the capacity to entertain a reasonable suspicion of criminal conduct.” (In re Tony C., at p. 894.) The reasonableness of the officer’s suspicion is determined by what he or she knows before any search occurs. (J.L., supra, 529 U.S. at p. 271.) And when a detention is constitutionally justified, if the officer has a reasonable suspicion that the person is armed and dangerous, the officer may pat search the detainee for weapons. (Terry, at p. 30.)

In determining the lawfulness of a temporary detention, courts look at the “ ‘totality of the circumstances’ of each case to see whether the detaining officer has a ‘particularized and objective basis’ for suspecting legal wrongdoing.” (United States v. Arvizu (2002) 534 U.S. 266, 273 [151 L.Ed.2d 740, 122 S.Ct. 744], quoting United States v. Cortez (1981) 449 U.S. 411, 417 [66 L.Ed.2d 621, 101 S.Ct. 690]; see People v. Souza (1994) 9 Cal.4th 224, 239 [36 Cal.Rptr.2d 569, 885 P.2d 982].) A balancing test is used to determine the constitutional validity of the detention: “The reasonableness of seizures that are less intrusive than a traditional arrest, [citations], depends ‘on a balance between the public interest and the individual’s right to personal security free from arbitrary interference by law officers.’ [Citations.] Consideration of the constitutionality of such seizures involves a weighing of the gravity of the public concerns served by the seizure, the degree to which the seizure advances the public interest, and the severity of the interference with individual liberty. [Citation.]” (Brown v. Texas (1979) 443 U.S. 47, 50-51 [61 L.Ed.2d 357, 99 S.Ct. 2637]; see United States v. Hensley (1985) 469 U.S. 221, 228 [83 L.Ed.2d 604, 105 S.Ct. 675] [test, based upon reasonableness standard under 4th Amend., “balances the nature and quality of the intrusion on personal security against the importance of the governmental interests alleged to justify the intrusion.”].)

The standard of “ ‘reasonable suspicion’ ... [is one] less demanding than probable cause ‘not only in the sense that reasonable suspicion can be established with information that is different in quantity or content than that required to establish probable cause, but also in the sense that reasonable suspicion can arise from information that is less reliable than that required to show probable cause.’ ” (People v. Souza, supra, 9 Cal.4th at pp. 230-231, quoting Alabama v. White (1990) 496 U.S. 325, 330 [110 L.Ed.2d 301, 110 S.Ct. 2412].) The United States Supreme Court has noted, “The concept of reasonable suspicion, like probable cause, is not ‘readily, or even usefully, reduced to a neat set of legal rules.’ [Citation.]” (United States v. Sokolow (1989) 490 U.S. 1, 7-8 [104 L.Ed.2d 1, 109 S.Ct. 1581], quoting Illinois v. Gates (1983) 462 U.S. 213, 232 [6 L.Ed.2d 527, 103 S.Ct. 2317].) Our high court has explained: “Although each case must be decided on its own facts, . . . [t]he guiding principle, as in all issues arising under the Fourth Amendment and under the California Constitution [citations], is ‘the reasonableness ... of the particular governmental invasion of a citizen’s personal security.’ [Citation.]” (In re Tony C., supra, 21 Cal.3d at p. 892, quoting Terry, supra, 392 U.S. at p. 19.)

II. Defendant’s Motion to Suppress

Defendant’s motion to suppress involves dual, alternative contentions. First, defendant argues that the officers’ action of handcuffing him at gunpoint was not a detention for which they would have needed a reasonable suspicion of criminal activity; rather, it constituted a de facto arrest, and the officers had no probable cause that defendant had committed a crime. Second, he argues that even were we to conclude that he was not arrested, his detention was unlawful because the detaining officers did not. have specific articulable facts upon which they could have reasonably suspected that he was involved in illegal activity. We address these two contentions below.

A. There Was No De Facto Arrest

Defendant claims that because his handcuffing at gunpoint during the encounter with the officers was not reasonably necessary, he was subjected to a de facto arrest. He bases this contention on the assertion that the officers could not have reasonably concluded that he was armed because “the source of the information was an unreliable anonymous tip.” We reject this argument.

An investigative detention, while its scope may vary depending on the individual circumstances, “must be temporary and last no longer than is necessary to effectuate the purpose of the stop. Similarly, the investigative methods employed should be the least intrusive means reasonably available to verify or dispel the officer’s suspicion in a short period of time. [Citations.]” (Florida v. Royer (1983) 460 U.S. 491, 500 [75 L.Ed.2d 229, 103 S.Ct. 1319].) Law enforcement’s purpose for the stop as well as the reasonable length of time necessary for the investigation should be considered in evaluating whether the intrusion is unreasonable and therefore a de facto arrest. (United States v. Sharpe (1985) 470 U.S. 675, 685 [84 L.Ed.2d 605, 105 S.Ct. 1568].) There is no “ ‘bright line’ rule,” and there “may in some instances [be] difficult line-drawing problems in distinguishing an investigative stop from a de facto arrest.” (Ibid., italics omitted; see People v. Celis (2004) 33 Cal.4th 667, 674-675 [16 Cal.Rptr.3d 85, 93 P.3d 1027] (Celis).)

A detention at gunpoint is a factor that obviously increases its intrusiveness; in some instances, this factor may result in the encounter being deemed an arrest that must be supported by probable cause, while in other instances, it may be found an appropriate element of the detention. (People v. Glaser (1995) 11 Cal.4th 354, 366 [45 Cal.Rptr.2d 425, 902 P.2d 729].) Similarly, handcuffing a suspect does not necessarily convert a detention into a de facto arrest. (Celis, supra, 33 Cal.4th at p. 675; see In re Antonio B. (2008) 166 Cal.App.4th 435, 441 [82 Cal.Rptr.3d 693].)

In Celis, the defendant, who was suspected of drug trafficking, claimed that he was subjected to a de facto arrest because he was detained outside his house at gunpoint, handcuffed, and required to sit on the ground for several minutes while officers walked through his house to ensure that there was no one inside posing a danger. (Celis, supra, 33 Cal.4th at p. 674.) In rejecting this claim, the court explained: “With regard to the scope, of the police intrusion, stopping a suspect at gunpoint, handcuffing him, and making him sit on the ground for a short period, as occurred here, do not convert a detention into an arrest. [Citations.]” (Id. at p. 675.) It explained that while such actions by officers would rarely be justified for a routine traffic stop, they “may be appropriate when the stop is of someone suspected of committing a felony.” (Id. at p. 676; see People v. Stier (2008) 168 Cal.App.4th 21, 27 [85 Cal.Rptr.3d 77] [officers’ handcuffing of suspect during detention generally held permissible only “where the police officer has a reasonable basis for believing the suspect poses a present physical threat or might flee”].)

Here, defendant was suspected of committing a felony—possession of a handgun on school property in violation of section 626.9, subdivision (b). Officer Hinze also understood that defendant had threatened a coach and had reportedly said that he intended to carry out that threat outside the stadium after the game. These circumstances justified Officer Hinze’s initial detention of defendant at gunpoint to safely ascertain whether defendant was carrying a firearm. The actions then taken by Officer White in furtherance of the investigative detention—also drawing his service weapon, ordering defendant to the ground, and handcuffing him—were likewise reasonable and appropriate in order to safely determine whether defendant was armed. (See, e.g., U.S. v. Greene (9th Cir. 1986) 783 F.2d 1364, 1368 [detention of the defendant and companion by officers with guns drawn reasonable where informant had indicated she had seen firearm in motel room of two men she described].) And it is apparent that the duration of the detention was brief, another important factor militating against concluding that defendant was subjected to a de facto arrest. (Celts, supra, 33 Cal.4th at p. 675.) Moreover, as we will discuss (see pt. II.B., post), there were sufficient articulable facts upon which the officers reasonably concluded that defendant was armed. Officers Hinze and White “were authorized to take such steps as were reasonably necessary to protect their personal safety and to maintain the status quo during the course of the stop.” (United States v. Hensley, supra, 469 U.S. at p. 235.) Accordingly, we reject defendant’s assertion that the officers’ actions constituted a de facto arrest.

B. The Detention Was Lawful

1. J.L., People v. Wells, and People v. Dolly

Defendant relies principally upon J.L., supra, 529 U.S. 266 in contending that his detention was unlawful because of the absence of facts supporting a reasonable suspicion of illegal activity. He argues that the basis for his detention by Officer Hinze was the “type of non-specific information . . . akin to an unreliable anonymous tip” which the Supreme Court declared in J.L. to be insufficient. He also asserts that People v. Dolly (2007) 40 Cal.4th 458 [53 Cal.Rptr.3d 803, 150 P.3d 693] (Dolly)—in which the California Supreme Court, distinguishing J.L., found lawful a detention that was based in part upon an anonymous tip—further supports his position that there was no reasonable suspicion supporting his detention.

In J.L., an anonymous caller reported to the police that a young Black male wearing a plaid shirt standing at a particular bus stop was carrying a gun. (J.L., supra, 529 U.S. at p. 268.) After an undisclosed period of time elapsed after receiving the tip, the police went to the bus stop, saw three Black males, and noted that the juvenile, J.L., was wearing a plaid shirt. (Ibid.) Based upon the anonymous tip, one of the officers contacted J.L., instructed him to put up his hands, and frisked him, finding a concealed gun. (Ibid.) The Supreme Court concluded that there were insufficient facts to support a reasonable suspicion that the juvenile was armed, because “the officers’ suspicion . . . arose not from any observations of their own but solely from a call made from an unknown location by an unknown caller.” (Id. at p. 270, italics added.) While the court acknowledged that “there are situations in which an anonymous tip, suitably corroborated, exhibits ‘sufficient indicia of reliability to provide reasonable suspicion to make the investigatory stop’ ” (ibid., quoting Alabama v. White, supra, 496 U.S. 325, 327), it concluded that a reasonable suspicion that the juvenile was armed could not be based upon “the bare report of an unknown, unaccountable informant who neither explained how he knew about the gun nor supplied any basis for believing he had inside information about J. L.” (J.L., at p. 271.)

In concluding that the uncorroborated anonymous tip did not support a reasonable suspicion of illegal activity, the Supreme Court rejected the State of Florida’s argument that there should be “an automatic firearm exception to [the court’s] reliability analysis,” which the court held “would rove too far [in that it] would enable any person seeking to harass another to set in motion an intrusive, embarrassing police search of the targeted person simply by placing an anonymous call falsely reporting the target’s unlawful carriage of a gun.” (J.L., supra, 529 U.S. at p. 272.) But it acknowledged that there might be some circumstances—such as a report of someone carrying a bomb—in which the exigencies might justify the investigative stop “even without a showing of reliability.” (Id. at p. 273.)

The California Supreme Court has distinguished J.L. in two subsequent cases upholding the constitutionality of detentions of suspects that were based in part upon anonymous tips. The reported criminal activity in the two cases involved suspected drunk driving (People v. Wells (2006) 38 Cal.4th 1078 [45 Cal.Rptr.3d 8, 136 P.3d 810] (Wells)) and an assault with a firearm (Dolly, supra, 40 Cal.4th 458).

In Wells, the court addressed whether an anonymous, “uncorroborated phoned-in tip that accurately describe[d] the vehicle and its location and relate[d] that a possibly intoxicated person [was] behind the wheel, ‘weaving all over the roadway’ ” justified an officer’s initiation of a traffic stop. (Wells, supra, 38 Cal.4th at p. 1081.) Less than a year later, in Dolly, our high court described its holding in Wells as follows: “After balancing the public interest in safety and the individual’s right to personal security free from arbitrary interference by law enforcement officers [citation], ... the relative urgency presented by drunk or erratic drivers could justify an investigatory detention based on an anonymous tip despite the absence of corroborating evidence of illegal activity.” (Dolly, supra, 40 Cal.4th at p. 464.)

In finding the officers’ conduct reasonable, the court in Wells distinguished J.L. on several bases. It explained that the tip concerning erratic driving was more reliable than J.L.’s anonymous tip of a concealed firearm “because the informant was presumably an eyewitness to illegal activity,” and the police could corroborate the tip by locating the described vehicle. (Wells, supra, 38 Cal.4th at p. 1086.) It observed further that questions about the reliability of the tip, by its very nature, were reduced because it was “a phoned-in report regarding a contemporaneous event of reckless driving presumably viewed by the caller.” (Id. at p. 1087.) Second, the tip included an accurate description of the vehicle and its location which was confirmed within minutes by the officer. (Wells, at p. 1088.) Third, the reported crime was qualitatively more serious than the crime reported in J.L.: “[A] report of a possibly intoxicated highway driver, ‘weaving all over the roadway,’ poses a far more grave and immediate risk to the public than a report of mere passive gun possession.” (Wells, at p. 1087.) Fourth, the traffic stop was less intrusive than the police search on a public street in J.L. (Wells, at p. 1087.) Based upon “the totality of the circumstances,” the court concluded that the officer had a reasonable suspicion for initiating the traffic stop. (Id. at p. 1088.)

In Dolly, supra, 40 Cal.4th at page 462, our high court considered whether officers were justified in conducting an investigative detention based upon two 911 calls from a person reporting that he had just been assaulted with a gun by a light-skinned Black male with a bandage over his left hand who had mentioned the name of a gang. The caller, who stated he would not talk to the police because he would be killed for “ ‘snitching,’ ” said the assailant was sitting in the driver’s seat of a car, and he described the car and its location. (Ibid.) Based upon this tip, the police went to the location; observed a car matching the description provided by the caller; identified the defendant in the driver’s seat who had a cast on his left arm; ordered him to exit the car and to lie down in the street; and found a loaded revolver under the front passenger seat. (Ibid.)

The court in Dolly held that the anonymous tip by the presumed assault victim was sufficiently reliable to justify the defendant’s detention. (Dolly, supra, 40 Cal.4th at p. 471.) It distinguished J.L. on the grounds that the nature of both the tips and the reported crimes in the two cases were significantly different. (Dolly, at pp. 465-469.) The court observed that the contemporaneous tip was at least as reliable as the phoned-in tip in Wells', in fact the tip in Dolly “bore stronger indicia of reliability” because it was a taped 911 call, presenting a greater possibility that the police could identify the caller. (Dolly, at p. 467.) And the court found that the tipster accurately and contemporaneously described the suspect and his location which the police confirmed within minutes and provided a plausible reason for not identifying himself. (Dolly, at pp. 468-469; see In re Richard G. (2009) 173 Cal.App.4th 1252, 1257-1258 [93 Cal.Rptr.3d 506] [detention upheld based on anonymous tip to police—that was at least as reliable as tip in Dolly—of contemporaneous late-night disturbance involving firearm in front of described house in gang territory which included description of people and their apparel].)

The court in Dolly reasoned further that the report of “pointing a revolver at the caller in an apparent threat to shoot him posed a grave and immediate risk not only to the caller but also to anyone nearby. [Citation.]” (Dolly, supra, 40 Cal.4th at p. 465.) It contrasted these circumstances with those in J.L., where “[a]n allegation concerning the possession of a concealed weapon ‘without more’ (J.L., supra, 529 U.S. at p. 268), does not present an emergency situation involving an immediate danger to human life.” (Dolly, at pp. 465-466.) Our high court explained: “In our view, the interest in protecting human life, even if insufficient in this case to dispense entirely with the need to demonstrate the anonymous tip’s reliability [citation], is nonetheless an important factor to consider in assessing the requisite level of reliability. [Citation.]” (Id. at p. 466.)

2. Defendant’s Detention Was Reasonable

In our consideration of the legality of the detention here, we consider “the totality of the circumstances” (Wells, supra, 38 Cal.4th at p. 1088) and balance “the gravity of the public concerns served by the seizure, the degree to which the seizure advances the public interest, and the severity of the interference with individual liberty. [Citation.]” (Brown v. Texas, supra, 443 U.S. at p. 51; see Dolly, supra, 40 Cal.4th at p. 464 [court balances “the public interest in safety and the individual’s right to personal security free from arbitrary interference by law enforcement officers”]). In implementing this test, we conclude that J.L. is distinguishable and that there were sufficient articulable facts giving rise to a reasonable suspicion that justified the officers’ detention of defendant.

Unlike in J.L., this is not a case in which the original tipster’s identity is unknown and he or she therefore cannot be held accountable to the police. The informant here was Ward, who told Officer Fenton (in Officer Hinze’s presence) that his aunt “knew someone who knew [defendant] and said he had a gun on him.” Thus, although the ultimate source that defendant was armed was not disclosed, Ward, unlike the anonymous tipster in J.L., was a known individual communicating the tip. He—like a known informant providing a tip to the police—had a “reputation [that could] be assessed and who [could] be held responsible if [his] allegations turn out to be fabricated.” (J.L., supra, 529 U.S. at p. 270; see id. at p. 276 (conc. opn. of Stevens, J.) [where “informant places his anonymity at risk,” court may consider this factor in assessing tip’s reliability].) Thus, we are not faced here with the inherent unreliability “of an unknown, unaccountable informant” as found in J.L. (id. at p. 271). Further, the tip concerned a named individual, defendant, whereas the suspect in J.L. was described as a young Black male wearing a plaid shirt. (Id. at p. 268.)

Additionally, Officer Hinze’s decision to detain defendant was based on more than Ward’s statement that he had heard defendant was carrying a gun. Officers Fenton and Hinze, who were together patrolling the parking lot, had been informed that defendant had threatened a coach; he had said that he would carry out that threat after the game outside the stadium, or, in Officer Hinze’s words, “[i]t was something [that] was going to be taken care of in the parking lot”; and the threat was taken seriously by the coaches, who accompanied their families to their cars for their protection.

Further, Officer Hinze, before detaining him, saw defendant congregating at the edge of a parking lot where there were strewn beer cans with five or six other people who had been seen in the same location before the game, and who “look[ed] a little intimidating.” Defendant broke away from the group and headed off campus very shortly after a marked police car arrived, an action which the trial court found as “adding to the suspicious activity of the defendant.” While such evidence of flight, of itself, is not sufficient to justify an investigative stop, it “is a proper consideration—and indeed can be a key factor—in determining whether in a particular case the police have sufficient cause to detain.” (People v. Souza, supra, 9 Cal.4th at p. 235; see U.S. v. Mayo (4th Cir. 2004) 361 F.3d 802, 807-808.) [fact that “upon seeing the police, Mayo sought to evade their scrutiny” was one factor supporting reasonable suspicion to detain suspect].) There was therefore significantly more evidence than “the bare report” of possible gun possession (J.L., supra, 529 U.S. at pp. 270-271) supporting Officer Hinze’s reasonable suspicion that defendant was engaged in illegal activity to justify the detention.

Defendant argues, however, that Officer Hinze’s testimony that he understood that “something was going to be taken care of in the parking lot” is vague and does not suggest criminal behavior (i.e., a planned assault) supporting the detention. We disagree. In the context of what was made known to Officer Hinze—including the prior threat upon the coach by defendant, and the fact that coaches were accompanying their families to their cars to ensure their safety—the officer could have reasonably believed that defendant was going to carry out his threat after the game in the parking lot. (People v. Jenkins, supra, 22 Cal.4th at p. 969.) And the fact that “something was going to be taken care of in the parking lot” may have a noncriminal meaning as well as a criminal one is not a basis for ignoring this evidence in evaluating whether there were articulable facts supporting a reasonable suspicion to detain defendant. (In re Tony C., supra, 21 Cal.Sd at p. 894.)

Moreover, considering, as part of the balance, “the gravity of the public concerns served by the seizure” (Brown v. Texas, supra, 443 U.S. at p. 51), there was a significantly greater threat to public safety than the reported conduct involved in J.L. The threat in J.L. was “a report of mere passive gun possession.” (Wells, supra, 38 Cal.4th at p. 1087.) Here, the reported gun possession on public high school grounds—a felony (§ 626.9, subd. (b))— occurring during the crowded conditions of a football game was coupled with a report that the armed person had threatened a coach and had indicated he would carry out the threat after the game. As the court found in Dolly, the report of “pointing a revolver at the caller in an apparent threat to shoot him posed a grave and immediate risk not only to the caller but also to anyone nearby” (Dolly, supra, 40 Cal.4th at p. 465), and presented exigent circumstances unlike those in J.L., where, in contrast, “[a]n allegation concerning the possession of a concealed weapon, ‘without more’ (J.L., supra, 529 U.S. at p. 268), does not present an emergency situation involving an immediate danger to human life.” (Dolly, at pp. 465-466.) Consistently with our high court’s conclusions regarding the severity of the reported crimes in both Wells and Dolly, the reported circumstances here presented a grave and immediate risk to the public. (See Dolly, at p. 465; Wells, at p. 1087; see also U.S. v. Wooden (7th Cir. 2008) 551 F.3d 647, 650 [“a need for dispatch can make reasonable a stop that would not be reasonable if the police had time to investigate at leisure”].)

We acknowledge that the intrusion to defendant in being publicly detained and handcuffed at gunpoint may have been greater than the traffic stop at issue in Wells, supra, 38 Cal.4th 1078. But the intrusiveness of the stop is only one of the factors to consider in determining whether the detention was reasonable, as seen, for example, in Dolly, where the defendant was ordered out of his car located on a city street in the middle of the afternoon and instructed to lie down in the street with his hands at his side. (Dolly, supra, 40 Cal.4th at p. 462.)

People v. Coulombe (2000) 86 Cal.App.4th 52 [102 Cal.Rptr.2d 798] (Coulombe) is instructive. In that case, during a “First Night” New Year’s Eve celebration, police received nearly simultaneous tips from two separate people (from whom police did not obtain identifying information) that a man wearing a white cap in a specified restaurant had a gun. (Id. at pp. 54-55.) Based upon this information, police located and approached the defendant, who was wearing a white cap and was sitting in a wheelchair in the area the witnesses described. (Id. at p. 55.) One officer asked the defendant if he was armed, and he responded that he was not, but clutched his right pants pocket; the officer placed his hand over the defendant’s hand, pat-searched him, and found a revolver. (Ibid.) The appellate court held that the trial court erred in granting the defendant’s suppression motion. It concluded that J.L., supra, 529 U.S. 266, was distinguishable, because in Coulombe, there were multiple tips and the tipsters contacted the police in person, and they thus “subjected themselves to scrutiny and the risk of losing their anonymity.” (Coulombe, at p. 58.) It also held that the circumstances of alleged gun possession were very different from those in J.L., because “the possession occurred not at a bus stop with only two of the suspect’s friends present, but rather in a throng of thousands of New Year’s Eve celebrants. The danger presented was thus much increased.” (Coulombe, at p. 58, fn. omitted.)

As was the case with the tipsters in Coulombe, Ward made himself the subject of potential scrutiny by the police; there may have been repercussions to him had his tip, learned through his aunt, ultimately been unfounded. Further, as was true in Coulombe, the risk was much greater than the risk in J.L. Here, there was a crowd of people leaving the football game and there was, in addition to gun possession, a report that defendant had threatened a coach and intended to follow up on the threat after the game. We concur with the Coulombe court’s comment, and find it equally applicable here: “We see no other reasonable course of action [the officers] could have taken to make that determination, without risking injury to themselves or those in the surrounding crowd, other than the one they engaged in.” (Coulombe, supra, 86 Cal.App.4th at pp. 59-60.)

Therefore, based upon the totality of the circumstances, we conclude that there were sufficient articulable facts to support a reasonable suspicion that defendant was armed, justifying his detention.

C. The Motion to Suppress Was Properly Denied

The actions taken by the officers over a brief period of time in holding defendant at gunpoint, ordering him to the ground, and handcuffing him were, under the circumstances, reasonably necessary in their investigation to determine whether defendant was armed. Their conduct was not so intrusive or unreasonable as to have constituted a de facto arrest. J.L. is factually distinguishable and does not compel the conclusion that the detention here was unlawful. After balancing the societal interest served by the detention against the individual’s “ ‘right to personal security free from arbitrary interference by law officers’ ” (Brown v. Texas, supra, 443 U.S. at p. 50), we conclude that the detention here was constitutionally permissible.

In reaching these conclusions, we cannot ignore that the reported crime here of carrying a concealed, loaded firearm serves as a grim reminder of the numerous mass shootings that have occurred in schools in the past decade or so, including: Columbine High School in 1999; Santana High School in 2001; Red Lake Senior High School in 2005; West Nickel Mines Amish School in 2006; Virginia Tech University in 2007; Northern Illinois University in 2008; University of Alabama (Huntsville) in 2010; Millard South High School in 2011; Chardon High School, Oikos University, and Sandy Hook Elementary School in 2012; Taft Union High School, Hazard Community and Technical College, and Santa Monica College in 2013. While the constitutional protections against unreasonable searches and seizures do not yield to public safety, neither is the Fourth Amendment an obstacle to vigilant security measures, such as detentions of suspects, taken to prevent mass violence (or violence of any kind) as long as the facts known to the officer(s) support a reasonable suspicion of criminal activity. Those facts existed here, and the motion to suppress was properly denied.

III.

DISPOSITION

The order of probation is modified: (1) As to the probation condition concerning drugs and alcohol, it shall be modified to read: “Not knowingly use or possess alcohol/narcotics, intoxicants, drugs, or other controlled substances without the prescription of a physician; not traffic in, or associate with persons known to defendant to use or traffic in narcotics or other controlled substances.” (2) As to the probation condition concerning weapons, the first sentence thereof shall be modified to read: “Not knowingly possess, receive or transport any firearm, ammunition or any deadly or dangerous weapon. . . .” As modified, the order of probation is affirmed.

Elia, Acting P. 1, and Bamattre-Manoukian, J., concurred.

Appellent’s petition for review by the Supreme Court was denied December 11, 2013, S213843. 
      
      Further statutory references are to the Penal Code unless otherwise stated.
     
      
      We infer from the record that Ward was the head coach, and Stewart was one of the assistant coaches.
     
      
      Ward testified that “[t]he crowd was chanting against our kids because we weren’t taking a knee.”
     
      
      Jeanette Smith testified briefly at the suppression hearing. As a friend of defendant and an admittedly reluctant witness called by the prosecution, Smith testified on direct examination that she attended the game; observed the crowd having become upset at the coaches approximately halfway through the game; and heard some discussion (while in Camel’s presence) about defendant possessing a gun. During her cross-examination and redirect, Smith testified that she heard the discussion about defendant having a gun after the game was over and was unsure whether it occurred before or after defendant was arrested.
     
      
      Shortly before defendant was stopped, a person was detained and searched by Officers Fenton and Hinze and Salinas Police Officer Jordan White. The person’s clothing did not match the description of defendant’s clothing, and the person was released. Simultaneously with Officer Hinze learning from a radio report that the detained person was not the person who was reportedly armed, the officer observed defendant and approached him.
     
      
      The record indicates that there was a second arrest after the game outside of the locker room involving Lenny Sanks (a relative of defendant), who had threatened Stewart and may have had a knife. Ward testified that he had seen Sanks with defendant during the game.
     
      
      The record reflects that at the time of his change of plea in this case, defendant admitted the allegations in the petition that he had violated probation in a separate misdemeanor case (No. MS276040). The court revoked probation, reinstated it on the original terms and conditions, and ordered defendant to serve 231 days in county jail with credits for an equal number of days, thereby deeming the jail sentence served.
     
      
      “Since the passage of Proposition 8 in 1982 (Cal. Const., art. I, § 28), the subjective belief of the citizen set. out in In re Tony C.[, supra,] 21 Cal.Sd 888, no longer applies in analyzing whether an encounter is a detention. [Citation.] Rather the federal standard of analyzing the objective facts of the incident controls. [Citation.]” (In re Christopher B. (1990) 219 Cal.App.3d 455,460, fn. 2 [268 Cal.Rptr. 8], citing In re Lance W. (1985) 37 Cal.3d 873 [210 Cal.Rptr. 631, 694 P.2d 744].)
     
      
      Defendant also addresses at some length the People’s contention below that the detention was justified because, under New Jersey v. T. L. O. (1985) 469 U.S. 325 [83 L.Ed.2d 720, 105 S.Ct. 733] (T.L.O.), there was a reduced expectation of privacy in a public school setting. In T.L.O., the United States Supreme Court recognized an exception to the warrant and probable cause requirement for searches conducted by public school officials. In respondent’s brief, the Attorney General cites T.L.O. and acknowledges the argument made by the People below, but she does not affirmatively make that argument here. Since the argument has not been made on appeal, and we will conclude, post, that the suppression motion was properly denied, we need not address this contention. (See People v. Jenkins, supra, 22 Cal.4th at p. 980, fn. 12 [where suppression motion was properly denied based on third party consent, appellate court declined to consider other claimed justifications for such denial].)
     
      
      Among the cases cited by the high court after the above quoted passage in which the appellate courts concluded that the officers’ conduct in detaining the suspect was not so intrusive or unreasonable as to have effected a de facto arrest are People v. Soun (1995) 34 Cal.App.4th 1499, 1517 [40 Cal.Rptr.2d 822], in which the defendant “was removed from the car at gunpoint by a large number of police officers, was forced to lie on the ground, was handcuffed and placed in a patrol car, was transported from the site of the stop a distance of three blocks to a parking lot,” where he was held for 30 minutes, and In re Carlos M. (1990) 220 Cal.App.3d 372, 384 [269 Cal.Rptr. 447], where officers, over a 30-minute period, handcuffed the defendant and drove him to the hospital for identification by a rape victim.
     
      
      “Any person who possesses a firearm in a place that the person knows, or reasonably should know, is a school zone, as defined in paragraph (1) of subdivision (e), unless it is with the written permission of the school district superintendent, his or her designee, or equivalent school authority, shall be punished as specified in subdivision (f).” (§ 626.9, subd. (b).) Subdivision (f) of section 626.9 makes the offense of possession of a firearm on school property punishable “by imprisonment pursuant to subdivision (h) of Section 1170 for two, three, or five years.”
     
      
      The high court also identified a policy reason for giving some weight to the reliability of a 911 call reporting a contemporaneous crime: “ ‘There is the equal danger, moreover, that according no weight to “anonymous” tips in the reasonable suspicion calculus will undermine the ability of concerned residents to report illegal activity and to thereby make their neighborhoods more safe. Residents of neighborhoods are in the best position to monitor activity on the streets. But residents, also fearful of the consequences, may not always wish to identify themselves and volunteer their names. According no weight as a matter of law to such “anonymous” tips would only discourage concerned residents from even calling the police, would burden the rights of ordinary citizens to live in their neighborhoods without fear and intimidation, and would render citizens helpless in their efforts to restore safety and sanctity to their homes and communities.’ [Citation.]” (Dolly, supra, 40 Cal.4th at p. 468, quoting U.S. v. Perkins (4th Cir. 2004) 363 F.3d 317, 326, fn. omitted.)
     
      
      As our high court has explained, a tip’s reliability need not be determined solely by whether it is predictive of the suspect’s future behavior or whether it is subject to corroboration. (Dolly, supra, 40 Cal.4th at p. 464; see id. at p. 470 [rejecting “rigid” approach to assessing tip’s reliability].)
     
      
      Defense counsel at oral argument contended that, regardless of the information Officer Fenton had received, Officer Hinze did not have sufficient facts supporting a reasonable suspicion to detain defendant. Counsel asserted that, because Officer Hinze was only aware of a threat made by an unspecified parent and that defendant was reported as having a gun, his information was insufficient to justify stopping defendant. We reject this argument for two reasons. First, it ignores the following testimony given by Officer Hinze during cross-examination about what he overheard when Ward was speaking to Officer Fenton: “Q. ... So the coach said he had a conflict on the football field with a parent and that his aunt believed he had a gun on his person? [¶] A. Correct. [¶] Q... . And Coach Ward also said that the parent threatened to take care of him after the game in the parking lot, is that correct? A. Correct.” There was thus a link between the threat and the gun—both involving defendant—that defense counsel argued was missing. Second, although it was Officer Fenton who spoke to Ward twice—during which Ward said that defendant had threatened a coach and that he (Ward) had heard that defendant “had a gun on him”—Officer Hinze was standing next to Officer Fenton at the time at a distance of an arm’s-length or less. Giving appropriate deference to the trial court’s express and implied factual findings, including its responsibility to weigh the evidence and draw appropriate factual inferences (People v. Jenkins, supra, 22 Cal.4th at p. 969; People v. Leyba, supra, 29 Cal.3d at p. 596), there is substantial evidence that Officer Hinze heard the substance of the conversations between Ward and Officer Fenton and thus understood that it was defendant who was both the source of the threat and was reported to be carrying a gun.
