    Before KING, Chief Judge, and HIGGINBOTHAM and DAVIS, Circuit Judges.
   PATRICK E. HIGGINBOTHAM, Circuit Judge:

This is an appeal from a denial of summary judgment to supervisory law enforcement officials in a suit brought under 42 U.S.C. § 1983. The district court denied the request for summary judgment premised on qualified immunity, finding genuine issues of material fact regarding supervisory liability and the objective reasonableness of the supervisors’ actions. Persuaded that the record cannot support a conclusion that supervisory liability would attach, we reverse.

I

Police Officer Allen L. Hill, a member of. the North Richland Hills Police Department (“NRHPD”) SWAT team, shot and killed Troy James Davis during the execution of a no-knock search and arrest warrant at the residence of Troy James Davis and Barbara Jean Davis. The circumstances of the raid are sharply contested.

Asserting claims pursuant to 42 U.S.C. § 1983 and state law, Davis’s estate and Davis’s mother, Barbara Jean Davis sued Chief of Police Tom Shockley, Police Officer J.A. Wallace, and Police Officer Allen Hill. Plaintiffs asserted that while executing the search and arrest warrant, Officer Hill used excessive force against Davis, shooting and killing him. Hill was the first SWAT team member to enter the home and he shot Davis within the initial two seconds. At the time, according to Plaintiffs, Davis was in his living room, unarmed, arms outstretched and repeating “don’t hurt us.” According to the police officers, upon entering the home, Hill was immediately confronted by an armed Davis standing at the end of the hallway, pointing a gun at Hill.

Plaintiffs further contended that Officer Wallace and Chief Shockley, two of Hill’s supervisors, should be held liable under section 1983 for their inadequate supervision and training of Hill, resulting in Hill’s use of excessive force during the raid. According to Plaintiffs, Wallace and Shockley knew prior to the shooting that Hill was “prone to use excessive and/or deadly force without cause,” that Hill had “a reputation for displaying lewd and criminal behavior while on and off-duty,” and that Hill’s “employment history branded and identified him as dysfunctional and unfit for police work.”

Shockley and Wallace, along with the other defendants, moved for summary judgment based on qualified immunity. The district court determined that Plaintiffs produced evidence demonstrating a genuine issue of material fact whether Shockley and Wallace were deliberately indifferent to Hill’s propensity to use excessive force, whether their conduct was objectively unreasonable in light of clearly established constitutional law.

The district court noted that the following evidence supported supervisory liability: testimony from Ann Shelton, a former member of the NRHPD SWAT team, iiidi-eating that Hill fired his weapon on three occasions during training exercises when the scenarios did not call for the firing of a weapon; a background investigation report indicating that Hill had a tendency to act too aggressively; and testimony of Randy Cole, a citizen who was pulled over by Hill for a traffic violation, indicating that Hill behaved “like a psycho” and was “going to kill somebody.” The district court found that the seriousness of the SWAT team training incidents was magnified when laid against Cole’s allegations. Further, the district court found evidence that Hill had a reputation for exposing himself," including during a team photograph at SWAT team training — a reputation that earned him the nickname “Pe-nie.”

The district court concluded that Shockley and Wallace were not as a matter of law entitled to qualified immunity on the supervisory liability claims and also denied summary judgment to Hill on the excessive force claim. Shockley and Wallace (“Appellants”) filed this appeal.

II

We must first address our jurisdiction. Ordinarily, we do not have jurisdiction to review a district court’s denial of a motion for summary judgment because such a decision is not a final judgment within the meaning of 28 U.S.C. § 1291. However, “a district court’s denial of a claim of qualified immunity, to the extent that it turns on an issue of law, is- an appealable ‘final decision’ within the meaning of 28 U.S.C. § 1291.”

“When a district court denies summary judgment on the basis that genuine issues of material fact exist, it has made two distinct legal conclusions: that there are ‘genuine’ issues of fact in dispute, and that these issues are ‘material.’ ” “ ‘[W]e can review the materiality of any factual disputes, but not their genuineness.’ “An officer challenges materiality when he contends that ‘taking all the plaintiffs factual allegations as true no violation of a clearly established right was shown.’ ” We determine whether a denial of summary judgment based on qualified immunity is immediately appealable by “looking] at the legal argument advanced.”

Appellants argue, inter alia, that even if Plaintiffs’ factual allegations are taken as taken as true, they are “not sufficient to constitute either gross negligence or deliberate indifference by the supervisors.” The issue of whether the evidence is sufficient to demonstrate deliberate indifference for supervisory liability is a legal issue that this court may review on interlocutory appeal. Appellants challenge the materiality of the disputed facts, and we have jurisdiction.

III

In an interlocutory appeal from the denial of a summary judgment motion based on qualified immunity, “we do not apply the standard of Rule 56 but instead consider only whether the district court erred in assessing the legal significance of the conduct that the district court deemed sufficiently supported for purposes of summary judgment.” We review de novo “the district court’s conclusions concerning the legal consequences — the materiality— of the facts.” We consider the facts in the light most favorable to Plaintiffs as the non-moving party.

IV

Appellants argue that Plaintiffs have not overcome the bar of qualified immunity— that there are no material issues of fact because, even in the light most favorable to Plaintiffs, the evidence is insufficient to demonstrate supervisory liability. We agree.

A

Under the doctrine of qualified immunity, “government officials performing discretionary functions generally are shielded from liability for civil damages insofar as their conduct does not violate clearly established statutory or constitutional rights of which a reasonable person would have known.” Qualified immunity is

an entitlement not to stand trial or face the other burdens of litigation, conditioned on the resolution of the essentially legal question whether the conduct of which the plaintiff complains violated clearly established law. The entitlement is an immunity from suit rather than a mere defense to liability ....

As we recently noted, “[b]efore this court — or any court — can adjudicate the merits” of Plaintiffs’ claims, they “must overcome the bar of qualified immunity.” Once raised, a plaintiff has the burden to rebut the qualified immunity defense “by establishing that the official’s allegedly wrongful conduct violated clearly established law. We do not require that an official demonstrate , that he did not violate clearly established federal rights; our precedent places that burden upon plaintiffs.” Qualified immunity “provides ample protection to all but the plainly incompetent or those who knowingly violate the law.”

B

Plaintiffs have alleged the violation of the constitutional right to be free of excessive force under the Fourth Amendment. Here, Plaintiffs seek to hold Appellants Wallace and Shockley liable as supervisors of Hill. Supervisory officials cannot be held liable under section 1983 for the actions of subordinates, such as Hill, on any theory of vicarious or respon-deat superior liability. Rather, Plaintiffs must show that the conduct of the supervisors denied Davis his constitutional rights. When, as here, a plaintiff alleges a failure to train or supervise, “the plaintiff must show that: (1) the supervisor either failed to supervise or train the subordinate official; (2) a causal link exists between the failure to train or supervise and the violation of the plaintiffs rights; and (3) the failure to train or supervise amounts to deliberate indifference.”

With respect to the third prong, we have on several occasions reversed a district court’s denial of qualified immunity, persuaded that support was lacking for a conclusion of deliberate indifference on the part of a supervisor. “ ‘[D]eliberate indifference’ is a stringent standard of fault, requiring proof that a municipal actor disregarded a known or obvious consequence of his action.” “For an official to act with deliberate indifference, the official must both be aware of facts from which the inference could be drawn that a substantial risk of serious harm exists, and he must also draw the inference.” Deliberate indifference requires a showing of more than negligence or even gross negligence. “Actions and decisions by officials that are merely inept, erroneous, ineffective, or negligent do not amount to deliberate indifference and do not divest officials of qualified immunity.” “To satisfy the deliberate indifference prong, a plaintiff usually must demonstrate a pattern of violations and that the inadequacy of the training is ‘obvious and obviously likely to result in a constitutional violation.’ ” “[I]t may happen that in light of the duties assigned to specific officers or employees the need for more or different training is so obvious, and the inadequacy so likely to result in the violation of constitutional rights,” a supervisor might reasonably be found to be deliberately indifferent.

C

We are persuaded that there is no material issue on the record before us with respect to the question of whether Appellants were deliberately indifferent. Because this case falters on the requirement of deliberate indifference, we need not address the other two prongs of supervisory liability.

The district court carefully detailed the evidence that Plaintiffs relied upon in support of their supervisory liability claims:

(1) testimony [regarding SWAT team training exercises] from Ann Shelton, a former NRHPD SWAT team member, indicating that Shockley and Wallace knew or should have known that Hill was likely to fire his weapon inappropriately or illegally;
(2) Shelton’s testimony that prior to the shooting of Troy Davis, when Hill intentionally exposed himself during the snapping of a team photograph at SWAT training exercise ... Shockley and Wallace failed to take adequate disciplinary action against Hill ...;
(3) evidence that Hill frequently exposed himself to other members of the NRHPD and, as a result, had acquired the nickname “Penie”;
(4) evidence in Hill’s background investigation showing Hill had a propensity for violence; [and]
(5) testimony that Shockley and Wallace failed to take any action after receiving a complaint from Randy Cole, a citizen who had been pulled over by Hill for a traffic violation prior to the shooting death of Troy Davis, [in the course of which Cole claimed to Shockley and Wallace that] Hill was a “rogue” cop, behaved “like a psycho” and was “going to kill somebody.”

Even accepted as true and taken as a whole, the above evidence is legally insufficient — and thus not material — to support a finding of deliberate indifference.

1

We are persuaded that these facts do not demonstrate a prior pattern by Hill of violating constitutional rights by employing excessive force. We have stressed that a single incident is usually insufficient to demonstrate deliberate indifference. In Cousin v. Small, for example, we held that “[t]o succeed on his claim of failure to train or supervise” the plaintiff must demonstrate deliberate indifference, which usually requires a plaintiff to “demonstrate a pattern of violations.” Similarly, in Snyder v. Trepagnier, we held that “proof of a single violent incident ordinarily is insufficient” for liability. Rather, the “plaintiff must demonstrate ‘at least a pattern of similar incidents in which the citizens were injured.’ Moreover, a showing of deliberate indifference requires that the Plaintiffs “show that the failure to train reflects a ‘deliberate’ or ‘conscious’ choice to endanger constitutional rights.”

Prior indications cannot simply be for any and all “bad” or unwise acts, but rather must point to the specific violation in question. That is, notice of a pattern of similar violations is required. While the specificity required should not be exaggerated, our cases require that the prior acts be fairly similar to what ultimately transpired and, in the case of excessive use of force, that the prior act have involved injury to a third party.

None of the facts highlighted by the district court indicated use of excessive force against a third party resulting in injury. First, while Hill’s over-“exposed” photography stunt and his earned nickname collectively demonstrate lack of judgment, crudity, and, perhaps illegalities, they do not point to past use of excessive force. Similarly, the traffic stop, while perhaps improper in its own right, did not involve excessive force with a deadly weapon resulting in harm to a citizen in a context similar to the present case.

By comparison, in Roberts v. City of Shreveport, we recently held that a habit of displaying a firearm during traffic stops does not constitute a relevant pattern with respect to using deadly force during a traffic stop. Here, there is no evidence that Hill had previously improperly displayed his weapon to a third party, or used excessive force.

Second, Hill’s inappropriate use of his gun during training is, at first blush, more troubling. Hill inappropriately fired his weapon in mock settings apparently much like the scene in which Hill ultimately shot Davis. However, because it was a training exercise it is undisputed that no one’s constitutional rights were violated and that Hill never used excessive force against a third party.

Furthermore, we hesitate in analyzing supervisory liability to place too much emphasis on mistakes during training. We are wary of creating incentives to conduct less training so as to minimize the chance that a subordinate will make a training mistake that can be used against the supervisor if that subordinate later makes a mistake in the course of duty. More to the point, in training mistakes are the fodder and “adequately trained officers oc-easionally make mistakes; the fact that they do says little about the training program or the legal basis” for holding a supervisor liable. Even if a fact finder were to infer that Hill’s training did not stick or that he resisted it, the incidents in training did not effect a violation of a third party’s rights. On this record, Appellants cannot be deemed deliberately indifferent by failing to supervise or train differently.

Third, as to the background report indicating that Hill “comes off too aggressive at times,” there is no evidence to suggest that either Wallace or Shockley was aware of it, and the district court did not impute knowledge of the report to either of them.

Finally, the facts here stand in stark contrast to those in a case like Camilo-Robles v. Hoyos where the First Circuit affirmed the denial of qualified immunity for police supervisory officials. In Camilo-Robles, the court recounted a subordinate officer’s service record, terming it “a career to make St. Sebastian weep.” The subordinate had a known history of assaulting his wife, holding hostages at gunpoint at the police station, assaulting another civilian, and shooting two law-abiding neighborhood residents (one of them died). In light of this background, the court held that qualified immunity was properly denied to police supervisors who had rearmed and helped put this officer back to work, at which point another incident predictably occurred. The present case, lacking a pattern of excessive force against a third party, falls far short of the subordinate’s “career” in Camilo-Robles.

In sum, there is no conduct from which it could be reasonably concluded that these supervisors made a deliberate or conscious choice to endanger' constitutional rights.

2

We do not suggest that a single incident, as opposed to a pattern of violations, can never suffice to demonstrate deliberate indifference. It is true that there is a so-called “single incident exception,” but it is inherently “a narrow one, and one that we have been reluctant to expand.” “To rely on this exception, a plaintiff must prove that the ‘highly predictable’ consequence of a failure to train would result in the specific injury suffered, and that the failure to train represented the ‘moving force’ behind the constitutional violation.” Hill’s history does not fall within this exception.

We did find a single incident to suffice in Brown v. Bryan County, concluding that there was an utter failure to train and supervise. We later observed that we found liability in Brown for a single incident when the county “failed to provide any training or supervision for a young, inexperienced officer with a record of recklessness,” while also noting that “there is a difference between a complete failure to train, as in [Brown v. Bryan County], and a failure to train in one limited area.”

In contrast, here, there was training and Plaintiffs have not shown that those training sessions were so deficient as to constitute deliberate indifference. The training sessions were in fact right on point, albeit a trier of fact might conclude not completely successful with Hill. It is not enough to say that more or different training or supervision would have prevented the result of the ill-fated raid.

We are persuaded that qualified immunity should have been granted to Shockley and Wallace and we must reverse the decision not to do so.

Id. at 798; see also Burge, 336 F.3d at 371 (evidence "not sufficient to establish deliberate indifference or knowledge” that a constitutional violation "would be a highly likely consequence”); cf.

      . See Roberts, 397 F.3d at 294 ("We do not deny that this evidence appears to reflect badly on [the subordinate's] judgment, but it proves nothing about [the subordinate’s] actual use of deadly force in the much different context of this case, nor is it relevant to whether [the supervisor] was on notice that [the subordinate] might use excessive force when confronted with a speeding vehicle while standing in the street directing traffic.”).
     
      
      . The district court recounted that Cole, in his complaint, stated that during the traffic stop Hill became "very angry ..., pounded on Cole's window, threatened to take him to jail, ordered him out of his car, and made him lean up against the car with his hands behind his back.” Davis, No. 4:00-CV-438-Y, at *45 n.50. Cole characterized Hill as a " 'rogue' cop” who "behaved like a psycho' and was 'going to kill somebody.’ " Id.
      
     
      
      . Cole's traffic stop allegations, even assuming them to be true and brought to the attention of Shockley and Wallace, are unsubstantiated. In Gros v. City of Grand Prairie, assessing a claim of deliberate indifference, we noted that although there was a complaint that the police officer improperly drew his weapon during a traffic stop, that complaint had not been sustained. 209 F.3d at 435.
      Another court has similarly refused to place much weight on such allegations in considering a municipality’s section 1983 liability and noted that "[i]t would be perverse to require that courts exclude allegations of past wrongdoing in order to protect the rights of defendants, while at the same time demanding that police officials give credence to unsubstantiated complaints against individual police officers.” Brooks v. Scheib, 813 F.2d 1191, 1194 (11th Cir.1987).
      This line of thinking is not without merit, helping to guard against allowing unsubstantiated complaints — of which, even in the absence of wrongdoing, there are likely many, especially by those on the receiving end of a traffic stop — to undermine the prohibition against collapsing supervisory liability into "functionally the respondeat superior regime the Supreme Court has repeatedly rejected.” Pineda v. City of Houston, 291 F.3d 325, 330 (5th Cir.2002); see Bryan County, 520 U.S. at 410, 117 S.Ct. 1382 ("To prevent municipal liability ... from collapsing into respondeat superior liability, a court must carefully test the link between the policymaker’s inadequate decision and the particular injury alleged.”); cf. Brooks, 813 F.2d at 1193 (“[T]he number of complaints bears no relation to their validity .... [T]here is a logical explanation as to why a large number of complaints have been lodged against [the officer]: [he] patrolled a high crime area [where] experienced 'customers' frequently use citizens' complaints as a means of harassing officers who arrest them.”).
      In any case, because there is no evidence that Hill used excessive force during the traffic stop, even giving the single complaint full credence, it is immaterial in the context of the record before us.

      Moreover, were we to analyze the evidence in the report in a manner similar to a deficient hiring case, it would fall short of the stringent standard for such cases. See Bryan County, 520 U.S. at 410, 117 S.Ct. 1382; Gros, 209 F.3d at 436; Aguillard v. McGowen, 207 F.3d 226 (5th Cir.2000).

      . We also note that we have never adopted the First Circuit’s test for deliberate indifference, which the district court followed. See Davis, No. 4:00-CV-438-Y, at *42 (” 'To demonstrate deliberate indifference a plaintiff must show (1) a grave risk of harm, (2) the defendant's actual or constructive knowledge of that risk, and (3) his failure to take easily available measures to address the risk.' ” (quoting Camilo-Robles, 151 F.3d at 7)).
