Maryland v. Buie/Opinion of the Court

A "protective sweep" is a quick and limited search of premises, incident to an arrest and conducted to protect the safety of police officers or others. It is narrowly confined to a cursory visual inspection of those places in which a person might be hiding. In this case we must decide what level of justification is required by the Fourth and Fourteenth Amendments before police officers, while effecting the arrest of a suspect in his home pursuant to an arrest warrant, may conduct a warrantless protective sweep of all or part of the premises. The Court of Appeals of Maryland held that a running suit seized in plain view during such a protective sweep should have been suppressed at respondent's armed robbery trial because the officer who conducted the sweep did not have probable cause to believe that a serious and demonstrable potentiality for danger existed. 314 Md. 151, 166, 550 A.2d 79, 86 (1988). We conclude that the Fourth Amendment would permit the protective sweep undertaken here if the searching officer "possesse[d] a reasonable belief based on 'specific and articulable facts which, taken together with the rational inferences from those facts, reasonably warrant[ed]' the officer in believing," Michigan v. Long, 463 U.S. 1032, 1049-1050, 103 S.Ct. 3469, 3480-3481, 77 L.Ed.2d 1201 (1983) (quoting Terry v. Ohio, 392 U.S. 1, 21, 88 S.Ct. 1868, 1880, 20 L.Ed.2d 889 (1968)), that the area swept harbored an individual posing a danger to the officer or others. We accordingly vacate the judgment below and remand for application of this standard.

* On February 3, 1986, two men committed an armed robbery of a Godfather's Pizza restaurant in Prince George's County, Maryland. One of the robbers was wearing a red running suit. That same day, Prince George's County police obtained arrest warrants for respondent Jerome Edward Buie and his suspected accomplice in the robbery, Lloyd Allen. Buie's house was placed under police surveillance.

On February 5, the police executed the arrest warrant for Buie. They first had a police department secretary telephone Buie's house to verify that he was home. The secretary spoke to a female first, then to Buie himself. Six or seven officers proceeded to Buie's house. Once inside, the officers fanned out through the first and second floors. Corporal James Rozar announced that he would "freeze" the basement so that no one could come up and surprise the officers. With his service revolver drawn, Rozar twice shouted into the basement, ordering anyone down there to come out. When a voice asked who was calling, Rozar announced three times: "this is the police, show me your hands." App. 5. Eventually, a pair of hands appeared around the bottom of the stairwell and Buie emerged from the basement. He was arrested, searched, and handcuffed by Rozar. Thereafter, Detective Joseph Frolich entered the basement "in case there was someone else" down there. Id., at 14. He noticed a red running suit lying in plain view on a stack of clothing and seized it.

The trial court denied Buie's motion to suppress the running suit, stating in part: "The man comes out from a basement, the police don't know how many other people are down there.  He is charged with a serious offense." Id., at 19. The State introduced the running suit into evidence at Buie's trial. A jury convicted Buie of robbery with a deadly weapon and using a handgun in the commission of a felony.

The Court of Special Appeals of Maryland affirmed the trial court's denial of the suppression motion. The court stated that Detective Frolich did not go into the basement to search for evidence, but to look for the suspected accomplice or anyone else who might pose a threat to the officers on the scene. 72 Md.App. 562, 571-572, 531 A.2d 1290, 1295 (1987).

"Traditionally, the sanctity of a person's home-his castle     requires that the police may not invade it without a warrant      except under the most exigent of circumstances.  But once the      police are lawfully within the home, their conduct is      measured by a standard of reasonableness. . . .  [I]f there      is reason to believe that the arrestee had accomplices who      are still at large, something less than probable cause      reasonable suspicion-should be sufficient to justify a      limited additional intrusion to investigate the possibility      of their presence." Id., at 575-576, 531 A.2d, at 1297     (emphasis in original).

The Court of Appeals of Maryland reversed by a 4-to-3 vote. 314 Md. 151, 550 A.2d 79 (1988). The court acknowledged that "when the intrusion is slight, as in the case of a brief stop and frisk on a public street, and the public interest in prevention of crime is substantial, reasonable articulable suspicion may be enough to pass constitutional muster," id., at 159, 550 A.2d, at 83. The court, however, stated that when the sanctity of the home is involved, the exceptions to the warrant requirement are few, and held: "[T]o justify a protective sweep of a home, the government must show that there is probable cause to believe that ' "a serious and demonstrable potentiality for danger" ' exists." Id., at 159-160, 550 A.2d, at 83 (citation omitted). The court went on to find that the State had not satisfied that probable-cause requirement. Id., at 165-166, 550 A.2d, at 86. We granted certiorari, 490 U.S. 1097, 109 S.Ct. 2447, 104 L.Ed.2d 1001 (1989). II

It is not disputed that until the point of Buie's arrest the police had the right, based on the authority of the arrest warrant, to search anywhere in the house that Buie might have been found, including the basement. "If there is sufficient evidence of a citizen's participation in a felony to persuade a judicial officer that his arrest is justified, it is constitutionally reasonable to require him to open his doors to the officers of the law." Payton v. New York, 445 U.S. 573, 602-603, 100 S.Ct. 1371, 1388-1389, 63 L.Ed.2d 639 (1980). There is also no dispute that if Detective Frolich's entry into the basement was lawful, the seizure of the red running suit, which was in plain view and which the officer had probable cause to believe was evidence of a crime, was also lawful under the Fourth Amendment. See Arizona v. Hicks, 480 U.S. 321, 326, 107 S.Ct. 1149, 1153, 94 L.Ed.2d 347 (1987). The issue in this case is what level of justification the Fourth Amendment required before Detective Frolich could legally enter the basement to see if someone else was there.

Petitioner, the State of Maryland, argues that, under a general reasonableness balancing test, police should be permitted to conduct a protective sweep whenever they make an in-home arrest for a violent crime. As an alternative to this suggested bright-line rule, the State contends that protective sweeps fall within the ambit of the doctrine announced in Terry v. Ohio, 392 U.S. 1, 88 S.Ct. 1868, 20 L.Ed.2d 889 (1968), and that such sweeps may be conducted in conjunction with a valid in-home arrest whenever the police reasonably suspect a risk of danger to the officers or others at the arrest scene. The United States, as amicus curiae supporting the State, also argues for a Terry-type standard of reasonable, articulable suspicion of risk to the officer, and contends that that standard is met here. Respondent argues that a protective sweep may not be undertaken without a warrant unless the exigencies of the situation render such warrantless search objectively reasonable. According to Buie, because the State has shown neither exigent circumstances to immediately enter Buie's house nor an unforeseen danger that arose once the officers were in the house, there is no excuse for the failure to obtain a search warrant to search for dangerous persons believed to be on the premises. Buie further contends that, even if the warrant requirement is inapplicable, there is no justification for relaxing the probable-cause standard. If something less than probable cause is sufficient, respondent argues that it is no less than individualized suspicion-specific, articulable facts supporting a reasonable belief that there are persons on the premises who are a threat to the officers. According to Buie, there were no such specific, articulable facts to justify the search of his basement.

It goes without saying that the Fourth Amendment bars only unreasonable searches and seizures, Skinner v. Railway Labor Executives' Assn., 489 U.S. 602, 109 S.Ct. 1402, 103 L.Ed.2d 639 (1989). Our cases show that in determining reasonableness, we have balanced the intrusion on the individual's Fourth Amendment interests against its promotion of legitimate governmental interests. United States v. Villamonte-Marquez, 462 U.S. 579, 588, 103 S.Ct. 2573, 2579, 77 L.Ed.2d 22 (1983); Delaware v. Prouse, 440 U.S. 648, 654, 99 S.Ct. 1391, 1396, 59 L.Ed.2d 660 (1979). Under this test, a search of the house or office is generally not reasonable without a warrant issued on probable cause. There are other contexts, however, where the public interest is such that neither a warrant nor probable cause is required. Skinner, supra, 489 U.S., at 619-620, 109 S.Ct., at 1414; Griffin v. Wisconsin, 483 U.S. 868, 873, 107 S.Ct. 3164, 3167, 97 L.Ed.2d 709 (1987); New Jersey v. T.L.O., 469 U.S. 325, 340-341, 105 S.Ct. 733, 742-743, 83 L.Ed.2d 720 (1985); Terry v. Ohio, 392 U.S., at 20, 88 S.Ct., at 1879.

The Terry case is most instructive for present purposes. There we held that an on-the-street "frisk" for weapons must be tested by the Fourth Amendment's general proscription against unreasonable searches because such a frisk involves "an entire rubric of police conduct-necessarily swift action predicated upon the on-the-spot observations of the officer on the beat-which historically has not been, and as a practical matter could not be, subjected to the warrant procedure." Ibid. We stated that there is " 'no ready test for determining reasonableness other than by balancing the need to search . . . against the invasion which the search . . . entails.' " Id., at 21, 88 S.Ct., at 1879 (quoting Camara v. Municipal Court of San Francisco, 387 U.S. 523, 536-537, 87 S.Ct. 1727, 1734-1735, 18 L.Ed.2d 930 (1967)). Applying that balancing test, it was held that although a frisk for weapons "constitutes a severe, though brief, intrusion upon cherished personal security," 392 U.S., at 24-25, 88 S.Ct., at 1881-1882, such a frisk is reasonable when weighed against the "need for law enforcement officers to protect themselves and other prospective victims of violence in situations where they may lack probable cause for an arrest." Id., at 24, 88 S.Ct., at 1881. We therefore authorized a limited patdown for weapons where a reasonably prudent officer would be warranted in the belief, based on "specific and articulable facts," id., at 21, 88 S.Ct., at 1880, and not on a mere "inchoate and unparticularized suspicion or 'hunch,' " id., at 27, 88 S.Ct., at 1883, "that he is dealing with an armed and dangerous individual," ibid.

In Michigan v. Long, 463 U.S. 1032, 103 S.Ct. 3469, 77 L.Ed.2d 1201 (1983), the principles of Terry were applied in the context of a roadside encounter: "[T]he search of the passenger compartment of an automobile, limited to those areas in which a weapon may be placed or hidden, is permissible if the police officer possesses a reasonable belief based on 'specific and articulable facts which, taken together with the rational inferences from those facts, reasonably warrant' the officer in believing that the suspect is dangerous and the suspect may gain immediate control of weapons." Id., at 1049-1050, 103 S.Ct., at 3480-3481 (quoting Terry, supra, 392 U.S., at 21, 88 S.Ct., at 1880). The Long Court expressly rejected the contention that Terry restricted preventative searches to the person of a detained suspect. 463 U.S., at 1047, 103 S.Ct., at 3479. In a sense, Long authorized a "frisk" of an automobile for weapons.

The ingredients to apply the balance struck in Terry and Long are present in this case. Possessing an arrest warrant and probable cause to believe Buie was in his home, the officers were entitled to enter and to search anywhere in the house in which Buie might be found. Once he was found, however, the search for him was over, and there was no longer that particular justification for entering any rooms that had not yet been searched.

That Buie had an expectation of privacy in those remaining areas of his house, however, does not mean such rooms were immune from entry. In Terry and Long we were concerned with the immediate interest of the police officers in taking steps to assure themselves that the persons with whom they were dealing were not armed with, or able to gain immediate control of, a weapon that could unexpectedly and fatally be used against them. In the instant case, there is an analogous interest of the officers in taking steps to assure themselves that the house in which a suspect is being, or has just been, arrested is not harboring other persons who are dangerous and who could unexpectedly launch an attack. The risk of danger in the context of an arrest in the home is as great as, if not greater than, it is in an on-the-street or roadside investigatory encounter. A Terry or Long frisk occurs before a police-citizen confrontation has escalated to the point of arrest. A protective sweep, in contrast, occurs as an adjunct to the serious step of taking a person into custody for the purpose of prosecuting him for a crime. Moreover, unlike an encounter on the street or along a highway, an in-home arrest puts the officer at the disadvantage of being on his adversary's "turf." An ambush in a confined setting of unknown configuration is more to be feared than it is in open, more familiar surroundings.

We recognized in Terry that "[e]ven a limited search of the outer clothing for weapons constitutes a severe, though brief, intrusion upon cherished personal security, and it must surely be an annoying, frightening, and perhaps humiliating experience." Terry, supra, 392 U.S., at 24-25, 88 S.Ct., at 1881-1882. But we permitted the intrusion, which was no more than necessary to protect the officer from harm. Nor do we here suggest, as the State does, that entering rooms not examined prior to the arrest is a de minimis intrusion that may be disregarded. We are quite sure, however, that the arresting officers are permitted in such circumstances to take reasonable steps to ensure their safety after, and while making, the arrest. That interest is sufficient to outweigh the intrusion such procedures may entail.

We agree with the State, as did the court below, that a warrant was not required. We also hold that as an incident to the arrest the officers could, as a precautionary matter and without probable cause or reasonable suspicion, look in closets and other spaces immediately adjoining the place of arrest from which an attack could be immediately launched. Beyond that, however, we hold that there must be articulable facts which, taken together with the rational inferences from those facts, would warrant a reasonably prudent officer in believing that the area to be swept harbors an individual posing a danger to those on the arrest scene. This is no more and no less than was required in Terry and Long, and as in those cases, we think this balance is the proper one. We should emphasize that such a protective sweep, aimed at protecting the arresting officers, if justified by the circumstances, is nevertheless not a full search of the premises, but may extend only to a cursory inspection of those spaces where a person may be found. The sweep lasts no longer than is necessary to dispel the reasonable suspicion of danger and in any event no longer than it takes to complete the arrest and depart the premises.

Affirmance is not required by Chimel v. California, 395 U.S. 752, 89 S.Ct. 2034, 23 L.Ed.2d 685 (1969), where it was held that in the absence of a search warrant, the justifiable search incident to an in-home arrest could not extend beyond the arrestee's person and the area from within which the arrestee might have obtained a weapon. First, Chimel was concerned with a full-blown search of the entire house for evidence of the crime for which the arrest was made, see id., at 754, 763, 89 S.Ct., at 2035, 2040, not the more limited intrusion contemplated by a protective sweep. Second, the justification for the search incident to arrest considered in Chimel was the threat posed by the arrestee, not the safety threat posed by the house, or more properly by unseen third parties in the house. To reach our conclusion today, therefore, we need not disagree with the Court's statement in Chimel, id., at 766-767, n. 12, 89 S.Ct., at 2041-2042, n. 12, that "the invasion of privacy that results from a top-to-bottom search of a man's house [cannot be characterized] as 'minor,' " nor hold that "simply because some interference with an individual's privacy and freedom of movement has lawfully taken place, further intrusions should automatically be allowed despite the absence of a warrant that the Fourth Amendment would otherwise require," ibid. The type of search we authorize today is far removed from the "top-to-bottom" search involved in Chimel; moreover, it is decidedly not "automati[c]," but may be conducted only when justified by a reasonable, articulable suspicion that the house is harboring a person posing a danger to those on the arrest scene.

We conclude that by requiring a protective sweep to be justified by probable cause to believe that a serious and demonstrable potentiality for danger existed, the Court of Appeals of Maryland applied an unnecessarily strict Fourth Amendment standard. The Fourth Amendment permits a properly limited protective sweep in conjunction with an in-home arrest when the searching officer possesses a reasonable belief based on specific and articulable facts that the area to be swept harbors an individual posing a danger to those on the arrest scene. We therefore vacate the judgment below and remand this case to the Court of Appeals of Maryland for further proceedings not inconsistent with this opinion.

It is so ordered.
