PER CURIAM.
Petitioners Darin Ryburn and Edmundo Zepeda, along with two other officers from the Burbank Police Department, responded to a call from Bellarmine-Jefferson High School in Burbank, California. When the officers arrived at the school, the principal informed them that a stu-dent, Vincent Huff, was rumored to have written a letter threatening to “shoot up” the school. App. to Pet. for Cert.
2. The principal reported that many parents, after hearing the rumor, had decided to keep their children at home. Ibid. The principal expressed concern for the safety of her students and requested that the officers investigate thethreat. Id., at 42, 54–55.
In the course of conducting interviews with the principaland two of Vincent’s classmates, the officers learned that Vincent had been absent from school for two days and that he was frequently subjected to bullying. Id., at 2. The officers additionally learned that one of Vincent’s classmates believed that Vincent was capable of carrying out the alleged threat. Id., at 44. The officers found Vincent’s absences from school and his history of being subjected tobullying as cause for concern. The officers had received training on targeted school violence and were aware that these characteristics are common among perpetrators ofschool shootings. Id., at 56–58, 63.
The officers decided to continue the investigation by interviewing Vincent. When the officers arrived at Vincent’s house, Officer Zepeda knocked on the door and announced several times that the officers were with the Burbank Police Department. No one answered the door or otherwise responded to Officer Zepeda’s knocks. Sergeant Ryburn then called the home telephone. The officers could hear the phone ringing inside the house, but no one answered. Id., at 2.
Sergeant Ryburn next tried calling the cell phone of Vincent’s mother, Mrs. Huff. When Mrs. Huff answered the phone, Sergeant Ryburn identified himself and inquired about her location. Mrs. Huff informed Sergeant Ryburn that she was inside the house. Sergeant Ryburnthen inquired about Vincent’s location, and Mrs. Huff informed him that Vincent was inside with her. SergeantRyburn told Mrs. Huff that he and the other officers wereoutside and requested to speak with her, but Mrs. Huffhung up the phone. Id., at 2–3.
One or two minutes later, Mrs. Huff and Vincent walked out of the house and stood on the front steps. Officer Zepeda advised Vincent that he and the other officers werethere to discuss the threats. Vincent, apparently aware of the rumor that was circulating at his school, responded, “I can’t believe you’re here for that.” Id., at 3. Sergeant Ryburn asked Mrs. Huff if they could continue the discussion inside the house, but she refused. Ibid. In SergeantRyburn’s experience as a juvenile bureau sergeant, it was“extremely unusual” for a parent to decline an officer’srequest to interview a juvenile inside. Id., at 3, 73–74. Sergeant Ryburn also found it odd that Mrs. Huff never asked the officers the reason for their visit. Id., at 73–74.
After Mrs. Huff declined Sergeant Ryburn’s request tocontinue the discussion inside, Sergeant Ryburn asked her if there were any guns in the house. Mrs. Huff responded by “immediately turn[ing] around and r[unning] into the house.” Id., at 3. Sergeant Ryburn, who was “scared because [he] didn’t know what was in that house” and had “seen too many officers killed,” entered the house behindher. Id., at 75. Vincent entered the house behind Sergeant Ryburn, and Officer Zepeda entered after Vincent.Officer Zepeda was concerned about “officer safety” and did not want Sergeant Ryburn to enter the house alone. Id., at 3. The two remaining officers, who had been standing out of earshot while Sergeant Ryburn and Officer Zepeda talked to Vincent and Mrs. Huff, entered the houselast, on the assumption that Mrs. Huff had given Sergeant Ryburn and Officer Zepeda permission to enter. Id., at 3–4.
Upon entering the house, the officers remained in theliving room with Mrs. Huff and Vincent. Eventually,Vincent’s father entered the room and challenged theofficers’ authority to be there. The officers remained inside the house for a total of 5 to 10 minutes. During thattime, the officers talked to Mr. Huff and Vincent. Theydid not conduct any search of Mr. Huff, Mrs. Huff, orVincent, or any of their property. The officers ultimatelyconcluded that the rumor about Vincent was false, and they reported their conclusion to the school. Id., at 4.
The Huffs brought this action against the officers underRev. Stat. §1979, 42 U. S. C. §1983. The complaint allegesthat the officers violated the Huffs’ Fourth Amendment rights by entering their home without a warrant. Following a 2-day bench trial, the District Court entered judgment in favor of the officers. The District Court resolved conflicting testimony regarding Mrs. Huff’s response to Sergeant Ryburn’s inquiry about guns by finding that Mrs. Huff “immediately turned around and ran into the house.” App. to Pet. for Cert. 3. The District Court concluded that the officers were entitled to qualified immunity because Mrs. Huff’s odd behavior, combined with the information the officers gathered at the school, could have led reasonable officers to believe “that there could be weapons insidethe house, and that family members or the officers themselves were in danger.” Id., at 6. The District Court noted that “[w]ithin a very short period of time, the officers were confronted with facts and circumstances giving rise to grave concern about the nature of the danger they were confronting.” Id., at 6–7. With respect to this kind of“rapidly evolving incident,” the District Court explained,courts should be especially reluctant “to fault the police fornot obtaining a warrant.” Id., at 7.
A divided panel of the Ninth Circuit affirmed the District Court as to the two officers who entered the house on the assumption that Mrs. Huff had consented, but reversed as to petitioners. The majority upheld the DistrictCourt’s findings of fact, but disagreed with the DistrictCourt’s conclusion that petitioners were entitled to qualified immunity. The majority acknowledged that policeofficers are allowed to enter a home without a warrant if they reasonably believe that immediate entry is necessaryto protect themselves or others from serious harm, even if the officers lack probable cause to believe that a crime hasbeen or is about to be committed. Id., at 24. But the majority determined that, in this case, “any belief thatthe officers or other family members were in serious, imminent harm would have been objectively unreasonable” given that “[Mrs. Huff] merely asserted her right to endher conversation with the officers and returned to her home.” Id., at 25.
Judge Rawlinson dissented. She explained that “thediscrete incident that precipitated the entry in this case was Mrs. Huff’s response to the question regarding whether there were guns in the house.” Id., at 31. She faulted the majority for “recit[ing] a sanitized account of this event” that differed markedly from the District Court’s findings of fact, which the majority had conceded must becredited. Judge Rawlinson looked to “cases that specifi-cally address the scenario where officer safety concernsprompted the entry” and concluded that, under the rationale articulated in those cases, “a police officer couldhave reasonably believed that he was justified in making a warrantless entry to ensure that no one inside the househad a gun after Mrs. Huff ran into the house without answering the question of whether anyone had a weapon.” Id., at 31, 33, 37.
Judge Rawlinson’s analysis of the qualified immunity issue was correct. No decision of this Court has found a Fourth Amendment violation on facts even roughly comparable to those present in this case. On the contrary,some of our opinions may be read as pointing in the opposition direction.
In Brigham City v. Stuart, 547 U. S. 398, 400 (2006), we held that officers may enter a residence without a warrant when they have “an objectively reasonable basis for believing that an occupant is . . . imminently threatened with [serious injury].” We explained that “‘[t]he need to protect or preserve life or avoid serious injury is justificationfor what would be otherwise illegal absent an exigency or emergency.’” Id., at 403 (quoting Mincey v. Arizona, 437 U. S. 385, 392 (1978)). In addition, in Georgia v. Randolph, 547 U. S. 103, 118 (2006), the Court stated that “it would be silly to suggest that the police would commit a tort by entering [a residence] . . . to determine whetherviolence . . . is about to (or soon will) occur.”
A reasonable police officer could read these decisions to mean that the Fourth Amendment permits an officer to en- ter a residence if the officer has a reasonable basis for concluding that there is an imminent threat of violence.In this case, the District Court concluded that petitioners had such an objectively reasonable basis for reaching sucha conclusion. The District Court wrote:
“[T]he officers testified that a number of factors ledthem to be concerned for their own safety and for thesafety of other persons in the residence: the unusual behavior of the parents in not answering the door orthe telephone; the fact that Mrs. Huff did not inquire about the reason for their visit or express concern thatthey were investigating her son; the fact that shehung up the telephone on the officer; the fact that she refused to tell them whether there were guns in the house; and finally, the fact that she ran back into the house while being questioned. That behavior, combined with the information obtained at the school—that Vincent was a student who was a victim of bullying, who had been absent from school for twodays, and who had threatened to ‘shoot up’ theschool—led the officers to believe that there could be weapons inside the house, and that family membersor the officers themselves were in danger.” App. toPet. for Cert. 6.
This belief, the District Court held, was “objectively reasonable,” particularly since the situation was “rapidly evolving” and the officers had to make quick decisions. Id., at 6–7.
The panel majority—far removed from the scene and with the opportunity to dissect the elements of the situation—confidently concluded that the officers really had no reason to fear for their safety or that of anyone else. As the panel majority saw things, it was irrelevant that the Huffs did not respond when the officers knocked on the door and announced their presence and when they called the home phone because the Huffs had no legal obligationto respond to a knock on the door or to answer the phone. The majority attributed no significance to the fact that, when the officers finally reached Mrs. Huff on her cell phone, she abruptly hung up in the middle of their conversation. And, according to the majority, the officers shouldnot have been concerned by Mrs. Huff’s reaction whenthey asked her if there were any guns in the house because Mrs. Huff “merely asserted her right to end herconversation with the officers and returned to her home.”
Id., at 25.
Confronted with the facts found by the District Court,reasonable officers in the position of petitioners could havecome to the conclusion that there was an imminent threat to their safety and to the safety of others. The Ninth Circuit’s contrary conclusion was flawed for numerous reasons.
First, although the panel majority purported to acceptthe findings of the District Court, it changed those findings in several key respects. As Judge Rawlinson correctlyobserved, “the discrete incident that precipitated the entryin this case was Mrs. Huff’s response to the question regarding whether there were guns in the house.” Id., at
31. The District Court’s finding that Mrs. Huff “immediately turned around and ran into the house” implicitly rejected Mrs. Huff’s contrary testimony that she walkedinto the house after telling the officers that she was going to get her husband. Id., at 3. The panel majority upheldthe District Court’s findings of fact and acknowledged thatit could not reverse the District Court simply because it“may have weighed the testimony of the witnesses andother evidence in another manner.” Id., at 15. But the panel majority’s determination that petitioners were not entitled to qualified immunity rested on an account of the facts that differed markedly from the District Court’s finding. According to the panel majority, Mrs. Huff “merely asserted her right to end her conversation with theofficers and returned to her home” after telling the officers“that she would go get her husband.” Id., at 12, 25.
Second, the panel majority appears to have taken theview that conduct cannot be regarded as a matter of concern so long as it is lawful. Accordingly, the panel ma-jority concluded that Mrs. Huff’s response to the question whether there were any guns in the house (immediately turning around and running inside) was not a reason for alarm because she was under no legal obligation to continue her conversation with the police. It should go without saying, however, that there are many circumstances in which lawful conduct may portend imminent violence.
Third, the panel majority’s method of analyzing thestring of events that unfolded at the Huff residence was entirely unrealistic. The majority looked at each separateevent in isolation and concluded that each, in itself, did not give cause for concern. But it is a matter of common sense that a combination of events each of which is mundane when viewed in isolation may paint an alarming picture.
Fourth, the panel majority did not heed the DistrictCourt’s wise admonition that judges should be cautious about second-guessing a police officer’s assessment, made on the scene, of the danger presented by a particular situation. With the benefit of hindsight and calm deliberation, the panel majority concluded that it was unreasonable for petitioners to fear that violence was imminent.But we have instructed that reasonableness “must be judged from the perspective of a reasonable officer on thescene, rather than with the 20/20 vision of hindsight” and that “[t]he calculus of reasonableness must embody allowance for the fact that police officers are often forced to make split-second judgments—in circumstances that aretense, uncertain, and rapidly evolving.” Graham v. Connor, 490 U. S. 386, 396–397 (1989). Judged from theproper perspective of a reasonable officer forced to make asplit-second decision in response to a rapidly unfoldingchain of events that culminated with Mrs. Huff turning and running into the house after refusing to answer a question about guns, petitioners’ belief that entry was necessary to avoid injury to themselves or others was im- minently reasonable.
In sum, reasonable police officers in petitioners’ positioncould have come to the conclusion that the Fourth Amendment permitted them to enter the Huff residence if
Per Curiam
there was an objectively reasonable basis for fearing thatviolence was imminent. And a reasonable officer could have come to such a conclusion based on the facts as found by the District Court.
The petition for certiorari is granted, the judgment ofthe Ninth Circuit is reversed, and the case is remanded for the entry of judgment in favor of petitioners.
It is so ordered.
