SUPREME COURT OF THE UNITED STATES

JUSTICE KAGAN delivered the opinion of the Court.
A police officer's use of deadly force violates the Fourth Amendment when it is not "objectively reasonable." Graham v. Connor, 490 U. S. 386, 397 (1989).  And that inquiry into reasonableness, we have held, requires assessing the "totality of the circumstances."  Id., at 396 (quoting Tennessee v. Garner, 471 U. S. 1, 9 (1985)).

The question here is whether that framework permits courts, in evaluating a police shooting (or other use of force), to apply the so-called moment-of-threat rule used in the courts below. Under that rule, a court looks only to the circumstances existing at the precise time an officer perceived the threat inducing him to shoot.  Today, we reject that approach as improperly narrowing the requisite Fourth Amendment analysis.  To assess whether an officer acted reasonably in using force, a court must consider all the relevant circumstances, including facts and events leading up to the climactic moment.

I

On the afternoon of April 28, 2016, Roberto Felix, Jr., a law enforcement officer patrolling a highway outside Houston, received a radio alert about an automobile on the road with outstanding toll violations.  Felix soon spotted the car, a Toyota Corolla, and turned on his emergency lights to initiate a traffic stop.  The driver, Ashtian Barnes, pulled over to the highway's shoulder.

 Parking his own car just behind, Felix walked to the Corolla's driver-side door and asked Barnes for his license and proof of insurance. Barnes replied that he did not have his license with him, and that the car was a rental in his girlfriend's name. As he spoke, Barnes rummaged through some papers inside the car, causing Felix to tell him several times to stop "digging around."  Felix also commented that he smelled marijuana, and asked if there was anything in the car he should know about.  Barnes responded that he might have some identification in the trunk.  So Felix told him to open the trunk from his seat.  Barnes did so, while also turning off the ignition.  All that happened (as a dashcam recording of the incident shows) in less than two minutes.  

 Then things began moving even faster.  With his right hand resting on his holster, Felix told Barnes to get out of the car. Barnes opened the door but did not exit; instead, he turned the ignition back on.  Felix unholstered his gun and, as the car began to move forward, jumped onto its doorsill.  He twice shouted, "Don't fucking move."  And with no visibility into the car (because his head was above the roof), he fired two quick shots inside. Barnes was hit, but managed to stop the car.  Felix then radioed for back-up.  By the time it arrived, Barnes was dead. All told, about five seconds elapsed between when the car started moving and when it stopped. And within that period, two seconds passed between the moment Felix stepped on the doorsill and the moment he fired his first shot.       

 Barnes's mother, Janice Barnes, sued Felix on her son's behalf.  The suit, brought under 42 U. S. C. §1983, alleged that Felix had violated Ashtian Barnes's Fourth Amendment rights by using excessive force against him.

The District Court granted summary judgment to Felix.  The court explained that to prevail on her claim, Mrs. Barnes needed to show that Felix's use of force was "objectively unreasonable." 532 F. Supp. 3d 463, 468 (SD Tex. 2021). In the usual excessive-force case, the court noted, the inquiry into reasonableness would involve considering a variety of circumstances.  See id., at 468–469. But when an officer has used deadly force, the court continued, "the Fifth Circuit has developed a much narrower approach."  Id., at 469. Then, a court could ask only about the situation existing "at the moment of the threat" that sparked the fatal shooting. Ibid. (quoting Rockwell v. Brown, 664 F. 3d 985, 991 (CA5 2011); emphasis in original).  The District Court identified that moment as "the two seconds before Felix fired his first shot," when he was standing on the doorsill of a moving vehicle. 532 F. Supp. 3d., at 471.  At that moment, the court found, an officer could reasonably think himself "at risk of serious harm."  Id., at 472.  And under the Fifth Circuit's rule, that fact alone concluded the analysis.  The court explained that it could not consider "what had transpired up until" those last two seconds, including Felix's decision to jump onto the sill. Id., at 471.  Although a "more robust examination" might have aided in assessing the reasonableness of the shooting, the court was "duty bound" by "Circuit precedent" to "limit[ its] focus" to the "exact moment Felix was hanging onto Barnes's" moving car.  Id., at 472.

The Court of Appeals affirmed, explaining that it too was "[b]ound" by "this Circuit's moment of threat doctrine."  91 F. 4th 393, 394, 397 (2024).  Under that rule, the panel agreed, the "inquiry is confined to whether the officer[]"  was "in danger at the moment of the threat that resulted in [his] use of deadly force."  Id., at 397. Any prior events "leading up to the shooting," including actions the officer took, were simply "not relevant." Ibid. (quoting Harris v. Serpas, 745 F. 3d 767, 772 (CA5 2014)).  And here, as the District Court found, the "precise moment of the threat" was the "two seconds" when Felix was clinging to a moving car. 91 F. 4th, at 397–398.  Because Felix could then have reasonably believed his life in danger, the panel concluded, his decision to shoot "did not violate Barnes's constitutional rights." Id., at 398.

 In a concurring opinion, Judge Higginbotham (who also authored the panel opinion) expressed "concern" with the Fifth Circuit's moment-of-threat doctrine. Ibid. He thought that rule inconsistent with this Court's directive to assess the reasonableness of an officer's use of force, including deadly force, by "look[ing] to the totality of circumstances." Id., at 399. Under the totality approach, Judge Higginbotham wrote, a court could consider not just the "precise millisecond" when an officer deploys force, but everything that "ha[d] transpired up until" that time.  Ibid. And with that wider focus, Judge Higginbotham would have found that Felix's shooting of Barnes was unreasonable. See id., at 401.      

We granted certiorari to address whether, in resolving Fourth Amendment excessive-force claims, courts may apply the moment-of-threat rule just described.  See 603 U. S. ___ (2024). We hold they may not because that rule constricts the proper inquiry into the "totality of the circumstances."

II

A claim that a law enforcement officer used excessive force during a stop or arrest is "analyzed under the Fourth Amendment." Graham, 490 U. S., at 395; see Amdt. 4 (applying to "seizures" of "persons").  The "touchstone of the Fourth Amendment is 'reasonableness,'" as measured in  objective terms. Brigham City v. Stuart, 547 U. S. 398, 403 (2006). So the question in a case like this one, as this Court has often held, is whether the force deployed was justified from "the perspective of a reasonable officer on the scene," taking due account of both the individual interests and the governmental interests at stake.  Graham, 490 U. S., at 396; County of Los Angeles v. Mendez, 581 U. S. 420, 428 (2017).
That inquiry into the reasonableness of police force requires analyzing the "totality of the circumstances."  Id., at 427–428; Garner, 471 U. S., at 9.  There is no "easy-to-apply legal test" or "on/off switch" in this context.  Scott v. Harris, 550 U. S. 372, 382–383 (2007).  Rather, the Fourth Amendment requires, as we once put it, that a court "slosh [its] way through" a "factbound morass."  Id., at 383.  Or said more prosaically, deciding whether a use of force was objectively reasonable demands "careful attention to the facts and circumstances" relating to the incident, as then known to the officer. Graham, 490 U. S., at 396.  For example, the "severity of the crime" prompting the stop can carry weight in the analysis. See ibid.; Garner, 471 U. S., at 11. So too  can actions the officer took during the stop, such as giving warnings or otherwise trying to control the encounter.  See id., at 12; Kingsley v. Hendrickson, 576 U. S. 389, 397 (2015). And the stopped person's conduct is always relevant because it indicates the nature and level of the threat he poses, either to the officer or to others.  See ibid.; Graham, 490 U. S., at 396.

 

 Most notable here, the "totality of the circumstances" inquiry into a use of force has no time limit.  Of course, the situation at the precise time of the shooting will often be what matters most; it is, after all, the officer's choice in that moment that is under review. But earlier facts and circumstances may bear on how a reasonable officer would have understood and responded to later ones. Or as the Federal Government puts the point, those later, "in-the-moment" facts "cannot be hermetically sealed off from the context in which they arose." Brief for United States as Amicus Curiae 14. Taking account of that context may benefit either party in an excessive-force case. Prior events may show, for example, why a reasonable officer would have perceived otherwise ambiguous conduct of a suspect as threatening.  Or instead they may show why such an officer would have perceived the same conduct as innocuous.  The history of the interaction, as well as other past circumstances known to the officer, thus may inform the reasonableness of the use of force.     

The Court's decision in Plumhoff v. Rickard, 572 U. S. 765 (2014), well illustrates the point.  The excessive-force claim there concerned the fatal shooting of a driver at the end of a "dangerous car chase" lasting more than five minutes. Id., at 768. The driver had sped away from a traffic stop on a well-used road, and tried to outrun as many as six police cruisers at speeds sometimes exceeding 100 miles per hour. Eventually, the fleeing car ran into one of the cruisers and came "to a near standstill."  Id., at 776. The driver, though, still tried to escape, pumping the gas in a way that sent his wheels "spinning" and then putting the car into reverse. Ibid. At that point, one of the officers fired several shots into the car. In a suit brought against the officer, the driver's daughter contended that those shots were taken when the chase was "already over."  Id., at 777.  But this Court rejected that claim based on everything that had happened during the incident—the driver's "outrageously reckless" behavior over the prior "five minutes," as well as his last-second efforts to again take flight.  Id., at 776. Given all of those events, the Court explained, a reasonable officer would have concluded that the driver was "intent on resuming" his getaway and, if allowed to do so, would "again pose a deadly threat for others."  Id., at 777.  In short, the shooting was justified "at the moment" it occurred partly because of what had transpired in the preceding period. Ibid.  

 The moment-of-threat rule applied in the courts below prevents that sort of attention to context, and thus conflicts with this Court's instruction to analyze the totality of the circumstances.  Recall that the District Court and Fifth Circuit limited their view to the two seconds before the shooting, after Felix had stepped onto the doorsill of Barnes's car.  See supra, at 3–4. Those courts believed that, under Fifth Circuit precedent, they could not take into account anything preceding that final moment.  See 532 F. Supp. 3d, at 471 (excluding analysis of "what had transpired up until the shooting itself"); 91 F. 4th, at 397 (agreeing that "actions leading up to the shooting are not relevant").  So, for example, they could not consider the reasons for the stop or the earlier conduct of, and interactions between, the suspect and officer. And because of that limit, they could not address whether the final two seconds of the encounter would look different if set within a longer timeframe.  It is as though the Court in Plumhoff could consider only the instant when the chased car was at a "near standstill," and not the earlier time when it zigzagged down a busy roadway at speed. 572 U. S., at 776.  To be sure, historical facts will not often matter as much as they did there to the reasonableness analysis.  See supra, at 6.  And some of those facts may not be relevant at all. But no rule that precludes consideration of prior events in assessing a police shooting is reconcilable with the fact-dependent and context-sensitive approach we have prescribed.  A court deciding a use-offorce case cannot review the totality of the circumstances if it has put on chronological blinders.    

That point is so evident that not even Felix quarrels with it; his defense of the decisions below instead relies on taking a different view of their meaning and of the question they raise. First, the agreement with what we have said: Yes, Felix acknowledges, prior events are not "off limits" in the reasonableness inquiry, for they may "inform the perspective of the reasonable officer." Tr. of Oral Arg. 79; Brief for Respondent 2. Just so.  But now the divergence: According to Felix, the courts below acted consistently with that alltimes-considered principle. The Fifth Circuit's moment-ofthreat doctrine, Felix argues, in fact allows courts to assess many pre-shooting facts and circumstances—and courts applying it often do so. See id., at 20 (citing other Fifth Circuit decisions). All that the doctrine bars is a single kind of in- quiry—into whether an officer's earlier error itself "created the need for deadly force." Id., at 21; see Tr. of Oral Arg. 53. And on that issue, Felix submits, the Fifth Circuit is right: "[A]n officer doesn't lose his right to defend himself just because" he previously "made a mistake." Ibid.          But whatever might be said of Fifth Circuit law generally, the decisions below applied a rule about timing. As shown above, both lower courts took pains to explain that, in evaluating the shooting's reasonableness, they could look only to a two-second snippet of the encounter.  See supra, at 3–4. And because that was the reasoning in the case before us, that is the reasoning we must address.  It could make no difference to our decision here if the Fifth Circuit in other cases eschewed a strict time limit, as Felix claims.  And anyway, we are not sure Felix correctly describes the overall state of Fifth Circuit law. Consider Harris v. Serpas—a Fifth Circuit decision relied on below.  See 91 F. 4th, at 397.  The court there noted the plaintiffs' recital of several historical facts—actions of both the suspect and the officer in the period prior to the shooting. See 745 F. 3d, at 772. And the court recognized that this Court's decisions directed an inquiry into the "the 'totality of the circumstances.'"   Ibid. (quoting Graham, 490 U. S., at 396).  But then came the following: "This [Circuit], however, has narrowed that test" in deadly force cases, holding that the inquiry there is "confined to whether the [officer] was in danger at the moment of the threat that resulted in the [officer's] shooting." Ibid. (alterations in original).  The problem with the statement is apparent. As we have explained, a court cannot thus "narrow" the totality-of-the-circumstances inquiry, to focus on only a single moment.  It must look too, in this and all excessive-force cases, at any relevant events coming before.

 We do not address here the different question Felix raises about use-of-force cases: whether or how an officer's own "creation of a dangerous situation" factors into the reasonableness analysis.  Brief for Respondent 22; see supra, at 8.  As in another of our recent Fourth Amendment cases, that issue is not properly before us.  See Mendez, 581 U. S., at 429, n. The courts below never confronted the issue, precisely because their inquiry was so time-bound.  In looking at only the two seconds before the shot, they excluded from view any actions of the officer that allegedly created the danger necessitating deadly force. See supra, at 3–4. So, to use the obvious example, the courts below did not address the relevance, if any, of Felix stepping onto the doorsill of Barnes's car.  And because they never considered that issue, it was not the basis of the petition for certiorari.  The question presented to us was one of timing alone: whether to look only at the encounter's final two seconds, or also to consider earlier events serving to put those seconds in context. With that matter resolved, we return everything else to the courts below. It is for them now to consider the reasonableness of the shooting, using the lengthier timeframe we have prescribed.

 Accordingly, we vacate the judgment of the Court of Appeals and remand the case for further proceedings consistent with this opinion.

It is so ordered.
