Police officers responded to a complaint of a disturbance near Allen Road in Brownstown, Michigan.
The officers knocked, but Fisher refused to answer. They saw that Fisher had a cut on his hand, and they asked him whether he needed medical attention. Fisher ignored these questions and demanded, with accompanying profanity, that the officers go to get a search warrant. Officer Goolsby then pushed the front door partway open and ventured into the house. Through the window of the open door he saw Fisher pointing a long gun at him. Officer Goolsby withdrew.
Fisher was charged under Michigan law with assault with a dangerous weapon and possession of a firearm during the commission of a felony. The trial court concluded that Officer Goolsby violated the Fourth Amendment when he entered Fisher’s house, and granted Fisher’s motion to suppress the evidence obtained as a result — that is, Officer Goolsby’s statement that Fisher pointed a rifle at him. The Michigan Court of Appeals initially remanded for an evidentiary hearing, see Docket No. 256027, 2005 WL 3481454 (Dec. 20, 2005) (per curiam), after which the trial court reinstated its order. The Court of Appeals then affirmed over a dissent by Judge Talbot. See 2008 WL 786515, at *2; id., at *2-*5. The Michigan Supreme Court granted leave to appeal, but, after hearing oral argument, it vacated its prior order and denied leave instead; three justices, however, would have taken the case and reversed on the ground that the Court of Appeals misapplied the Fourth Amendment. [47]*47See 483 Mich. 1007, 765 N. W. 2d 19 (2009). Because the decision of the Michigan Court of Appeals is indeed contrary to our Fourth Amendment ease law, particularly Brigham City v. Stuart, 547 U. S. 398 (2006), we grant the State’s petition for certiorari and reverse.
“[T]he ultimate touchstone of the Fourth Amendment,” we have often said, “is ‘reasonableness.’ ” Id., at 403. Therefore, although “searches and seizures inside a home without a warrant are presumptively unreasonable,” Groh v. Ramirez, 540 U. S. 551, 559 (2004) (internal quotation marks omitted), that presumption can be overcome. For example, “the exigencies of the situation [may] make the needs of law enforcement so compelling that the warrantless search is objectively reasonable.” Mincey v. Arizona, 437 U. S. 385, 393-394 (1978) (internal quotation marks omitted).
Brigham City identified one such exigency: “the need to assist persons who are seriously injured or threatened with such injury.” 547 U. S., at 403. Thus, law enforcement officers “may enter a home without a warrant to render emergency assistance to an injured occupant or to protect an occupant from imminent injury.” Ibid. This “emergency aid exception” does not depend on the officers’ subjective intent or the seriousness of any crime they are investigating when the emergency arises. Id., at 404-405. It requires only “an objectively reasonable basis for believing,” id., at 406, that “a person within [the house] is in need of immediate aid,” Mincey, supra, at 392.
Brigham City illustrates the application of this standard. There, police officers responded to a noise complaint in the early hours of the morning. “As they approached the house, they could hear from within an altercation occurring, some kind of fight.” 547 U. S., at 406 (internal quotation marks omitted). Following the tumult to the back of the house whence it came, the officers saw juveniles drinking beer in the backyard and a fight unfolding in the kitchen. They [48]*48watched through the window as a juvenile broke free from the adults restraining him and punched another adult in the face, who recoiled to the sink, spitting blood. Ibid. Under these circumstances, we found it “plainly reasonable” for the officers to enter the house and quell the violence, for they had “an objectively reasonable basis for believing both that the injured adult might need help and that the violence in the kitchen was just beginning.” Ibid.
A straightforward application of the emergency aid exception, as in Brigham, City, dictates that the officer’s entry was reasonable. Just as in Brigham City, the police officers here were responding to a report of a disturbance. Just as in Brigham City, when they arrived on the scene they encountered a tumultuous situation in the house — and here they also found signs of a recent injury, perhaps from a car accident, outside. And just as in Brigham City, the officers could see violent behavior inside. Although Officer Goolsby and his partner did not see punches thrown, as did the officers in Brigham City, they did see Fisher screaming and throwing things. It would be objectively reasonable to believe that Fisher’s projectiles might have a human target (perhaps a spouse or a child), or that Fisher would hurt himself in the course of his rage. In short, we find it as plain here as we did in Brigham City that the officer’s entry was reasonable under the Fourth Amendment.
The Michigan Court of Appeals, however, thought the situation “did not rise to a level of emergency justifying the warrantless intrusion into a residence.” 2008 WL 786515, at *2. Although the Court of Appeals conceded that “there was evidence an injured person was on the premises,” it found it significant that “the mere drops of blood did not signal a likely serious, life-threatening injury.” Ibid. The court added that the cut Officer Goolsby observed on Fisher’s hand “likely explained the trail of blood” and that Fisher “was very much on his feet and apparently able to see to his own needs.” Ibid.
[49]*49Even a casual review of Brigham City reveals the flaw in this reasoning. Officers do not need ironclad proof of “a likely serious, life-threatening” injury to invoke the emergency aid exception. The only injury police could confirm in Brigham City was the bloody lip they saw the juvenile inflict upon the adult. Fisher argues that the officers here could not have been motivated by a perceived need to provide medical assistance, since they never summoned emergency medical personnel.

Officers do not need ironclad proof of “a likely serious, life-threatening” injury to invoke the emergency aid exception. The only injury police could confirm in Brigham City was the bloody lip they saw the juvenile inflict upon the adult. Fisher argues that the officers here could not have been motivated by a perceived need to provide medical assistance, since they never summoned emergency medical personnel. This would have no bearing, of course, upon their need to ensure that Fisher was not endangering someone else in the house. Moreover, even if the failure to summon medical personnel conclusively established that Goolsby did not subjectively believe, when he entered the house, that Fisher or someone else was seriously injured (which is doubtful), the test, as we have said, is not what Goolsby believed, but whether there was “an objectively reasonable basis for believing” that medical assistance was needed, or persons were in danger, Brigham City, supra, at 406; Mincey, supra, at 392.
It was error for the Michigan Court of Appeals to replace that objective inquiry into appearances with its hindsight determination that there was in fact no emergency. It does not meet the needs of law enforcement or the demands of public safety to require officers to walk away from a situation like the one they encountered here. Only when an apparent threat has become an actual harm can officers rule out innocuous explanations for ominous circumstances. But “[t]he role of a peace officer includes preventing violence and restoring order, not simply rendering first aid to casualties.” Brigham City, supra, at 406. It sufficed to invoke the emergency aid exception that it was reasonable to believe that Fisher had hurt himself (albeit nonfatally) and needed treatment that in his rage he was unable to provide, or that Fisher was about to hurt, or had already hurt, someone else. The Michigan Court of Appeals required more than what the Fourth Amendment demands.
