# Terry v. Ohio *Terry v. Ohio*, which sets forth the doctrine permitting “stop and frisk” in some circumstances and which has given its name to the practice. Before diving into the court's decision, here is a video preview: {% embed url="" %} *** [392 U.S. 1](https://scholar.google.com/scholar_case?case=17773604035873288886\&q=392+U.S.+1\&hl=en\&as_sdt=6,50) (1968) Supreme Court of the United States **Terry v. Ohio** Mr. Chief Justice WARREN delivered the opinion of the Court. This case presents serious questions concerning the role of the Fourth Amendment in the confrontation on the street between the citizen and the policeman investigating suspicious circumstances. Petitioner Terry was convicted of carrying a concealed weapon and sentenced to the statutorily prescribed term of one to three years in the penitentiary. Following the denial of a pretrial motion to suppress, the prosecution introduced in evidence two revolvers and a number of bullets seized from Terry and a codefendant, Richard Chilton, by Cleveland Police Detective Martin McFadden. At the hearing on the motion to suppress this evidence, Officer McFadden testified that while he was patrolling in plain clothes in downtown Cleveland at approximately 2:30 in the afternoon of October 31, 1963, his attention was attracted by two men, Chilton and Terry, standing on the corner of Huron Road and Euclid Avenue. He had never seen the two men before, and he was unable to say precisely what first drew his eye to them. However, he testified that he had been a policeman for 39 years and a detective for 35 and that he had been assigned to patrol this vicinity of downtown Cleveland for shoplifters and pickpockets for 30 years. He explained that he had developed routine habits of observation over the years and that he would “stand and watch people or walk and watch people at many intervals of the day.” He added: “Now, in this case when I looked over they didn’t look right to me at the time.” His interest aroused, Officer McFadden took up a post of observation in the entrance to a store 300 to 400 feet away from the two men. “I get more purpose to watch them when I seen their movements,” he testified. He saw one of the men leave the other one and walk southwest on Huron Road, past some stores. The man paused for a moment and looked in a store window, then walked on a short distance, turned around and walked back toward the corner, pausing once again to look in the same store window. He rejoined his companion at the corner, and the two conferred briefly. Then the second man went through the same series of motions, strolling down Huron Road, looking in the same window, walking on a short distance, turning back, peering in the store window again, and returning to confer with the first man at the corner. The two men repeated this ritual alternately between five and six times apiece—in all, roughly a dozen trips. At one point, while the two were standing together on the corner, a third man approached them and engaged them briefly in conversation. This man then left the two others and walked west on Euclid Avenue. Chilton and Terry resumed their measured pacing, peering and conferring. After this had gone on for 10 to 12 minutes, the two men walked off together, heading west on Euclid Avenue, following the path taken earlier by the third man. By this time Officer McFadden had become thoroughly suspicious. He testified that after observing their elaborately casual and oft-repeated reconnaissance of the store window on Huron Road, he suspected the two men of “casing a job, a stick-up,” and that he considered it his duty as a police officer to investigate further. He added that he feared “they may have a gun.” Thus, Officer McFadden followed Chilton and Terry and saw them stop in front of Zucker’s store to talk to the same man who had conferred with them earlier on the street corner. Deciding that the situation was ripe for direct action, Officer McFadden approached the three men, identified himself as a police officer and asked for their names. At this point his knowledge was confined to what he had observed. He was not acquainted with any of the three men by name or by sight, and he had received no information concerning them from any other source. When the men “mumbled something” in response to his inquiries, Officer McFadden grabbed petitioner Terry, spun him around so that they were facing the other two, with Terry between McFadden and the others, and patted down the outside of his clothing. In the left breast pocket of Terry’s overcoat Officer McFadden felt a pistol. He reached inside the overcoat pocket, but was unable to remove the gun. At this point, keeping Terry between himself and the others, the officer ordered all three men to enter Zucker’s store. As they went in, he removed Terry’s overcoat completely, removed a .38-caliber revolver from the pocket and ordered all three men to face the wall with their hands raised. Officer McFadden proceeded to pat down the outer clothing of Chilton and the third man, Katz. He discovered another revolver in the outer pocket of Chilton’s overcoat, but no weapons were found on Katz. The officer testified that he only patted the men down to see whether they had weapons, and that he did not put his hands beneath the outer garments of either Terry or Chilton until he felt their guns. So far as appears from the record, he never placed his hands beneath Katz’ outer garments. Officer McFadden seized Chilton’s gun, asked the proprietor of the store to call a police wagon, and took all three men to the station, where Chilton and Terry were formally charged with carrying concealed weapons. On the motion to suppress the guns the prosecution took the position that they had been seized following a search incident to a lawful arrest. The trial court rejected this theory, stating that it “would be stretching the facts beyond reasonable comprehension” to find that Officer McFadden had had probable cause to arrest the men before he patted them down for weapons. However, the court denied the defendants’ motion on the ground that Officer McFadden, on the basis of his experience, “had reasonable cause to believe … that the defendants were conducting themselves suspiciously, and some interrogation should be made of their action.” Purely for his own protection, the court held, the officer had the right to pat down the outer clothing of these men, who he had reasonable cause to believe might be armed. The court distinguished between an investigatory “stop” and an arrest, and between a “frisk” of the outer clothing for weapons and a full-blown search for evidence of crime. The frisk, it held, was essential to the proper performance of the officer’s investigatory duties, for without it “the answer to the police officer may be a bullet, and a loaded pistol discovered during the frisk is admissible.” After the court denied their motion to suppress, Chilton and Terry waived jury trial and pleaded not guilty. The court adjudged them guilty, and the Court of Appeals for the Eighth Judicial District, Cuyahoga County, affirmed. The Supreme Court of Ohio dismissed their appeal. We granted certiorari. We affirm the conviction. **I** The question is whether in all the circumstances of this on-the-street encounter, \[Terry’s] right to personal security was violated by an unreasonable search and seizure. We would be less than candid if we did not acknowledge that this question thrusts to the fore difficult and troublesome issues regarding a sensitive area of police activity—issues which have never before been squarely presented to this Court. Reflective of the tensions involved are the practical and constitutional arguments pressed with great vigor on both sides of the public debate over the power of the police to “stop and frisk”—as it is sometimes euphemistically termed—suspicious persons. On the one hand, it is frequently argued that in dealing with the rapidly unfolding and often dangerous situations on city streets the police are in need of an escalating set of flexible responses, graduated in relation to the amount of information they possess. For this purpose it is urged that distinctions should be made between a “stop” and an “arrest” (or a “seizure” of a person), and between a “frisk” and a “search.” On the other side the argument is made that the authority of the police must be strictly circumscribed by the law of arrest and search. It is contended with some force that there is not—and cannot be—a variety of police activity which does not depend solely upon the voluntary cooperation of the citizen and yet which stops short of an arrest based upon probable cause to make such an arrest. In this context we approach the issues in this case mindful of the limitations of the judicial function in controlling the myriad daily situations in which policemen and citizens confront each other on the street. No judicial opinion can comprehend the protean variety of the street encounter, and we can only judge the facts of the case before us. Nothing we say today is to be taken as indicating approval of police conduct outside the legitimate investigative sphere. Under our decision, courts still retain their traditional responsibility to guard against police conduct which is over-bearing or harassing, or which trenches upon personal security without the objective evidentiary justification which the Constitution requires. Having thus roughly sketched the perimeters of the constitutional debate over the limits on police investigative conduct in general and the background against which this case presents itself, we turn our attention to the quite narrow question posed by the facts before us: whether it is always unreasonable for a policeman to seize a person and subject him to a limited search for weapons unless there is probable cause for an arrest. **II** Our first task is to establish at what point in this encounter the Fourth Amendment becomes relevant. That is, we must decide whether and when Officer McFadden “seized” Terry and whether and when he conducted a “search.” There is some suggestion in the use of such terms as “stop” and “frisk” that such police conduct is outside the purview of the Fourth Amendment because neither action rises to the level of a “search” or “seizure” within the meaning of the Constitution. We emphatically reject this notion. It is quite plain that the Fourth Amendment governs “seizures” of the person which do not eventuate in a trip to the station house and prosecution for crime—“arrests” in traditional terminology. It must be recognized that whenever a police officer accosts an individual and restrains his freedom to walk away, he has “seized” that person. And it is nothing less than sheer torture of the English language to suggest that a careful exploration of the outer surfaces of a person’s clothing all over his or her body in an attempt to find weapons is not a “search.” Moreover, it is simply fantastic to urge that such a procedure performed in public by a policeman while the citizen stands helpless, perhaps facing a wall with his hands raised, is a “petty indignity.” It is a serious intrusion upon the sanctity of the person, which may inflict great indignity and arouse strong resentment, and it is not to be undertaken lightly. The danger in the logic which proceeds upon distinctions between a “stop” and an “arrest,” or “seizure” of the person, and between a “frisk” and a “search” is twofold. It seeks to isolate from constitutional scrutiny the initial stages of the contact between the policeman and the citizen. And … it obscures the utility of limitations upon the scope, as well as the initiation, of police action as a means of constitutional regulation. This Court has held in the past that a search which is reasonable at its inception may violate the Fourth Amendment by virtue of its intolerable intensity and scope. The scope of the search must be “strictly tied to and justified by” the circumstances which rendered its initiation permissible. The distinctions of classical “stop-and-frisk” theory thus serve to divert attention from the central inquiry under the Fourth Amendment—the reasonableness in all the circumstances of the particular governmental invasion of a citizen’s personal security. “Search” and “seizure” are not talismans. We therefore reject the notions that the Fourth Amendment does not come into play at all as a limitation upon police conduct if the officers stop short of something called a “technical arrest” or a “full-blown search.” In this case there can be no question, then, that Officer McFadden “seized” petitioner and subjected him to a “search” when he took hold of him and patted down the outer surfaces of his clothing. We must decide whether at that point it was reasonable for Officer McFadden to have interfered with petitioner’s personal security as he did. And in determining whether the seizure and search were “unreasonable” our inquiry is a dual one—whether the officer’s action was justified at its inception, and whether it was reasonably related in scope to the circumstances which justified the interference in the first place. **III** If this case involved police conduct subject to the Warrant Clause of the Fourth Amendment, we would have to ascertain whether “probable cause” existed to justify the search and seizure which took place. However, that is not the case. \[W]e deal here with 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. Instead, the conduct involved in this case must be tested by the Fourth Amendment’s general proscription against unreasonable searches and seizures. In order to assess the reasonableness of Officer McFadden’s conduct as a general proposition, it is necessary “first to focus upon the governmental interest which allegedly justifies official intrusion upon the constitutionally protected interests of the private citizen,” for there is “no ready test for determining reasonableness other than by balancing the need to search (or seize) against the invasion which the search (or seizure) entails.” And in justifying the particular intrusion the police officer must be able to point to specific and articulable facts which, taken together with rational inferences from those facts, reasonably warrant that intrusion. \[I]t is imperative that the facts be judged against an objective standard: would the facts available to the officer at the moment of the seizure or the search “warrant a man of reasonable caution in the belief” that the action taken was appropriate? And simple “‘good faith on the part of the arresting officer is not enough.’ If subjective good faith alone were the test, the protections of the Fourth Amendment would evaporate, and the people would be ‘secure in their persons, houses, papers and effects,’ only in the discretion of the police.” Applying these principles to this case, we consider first the nature and extent of the governmental interests involved. One general interest is of course that of effective crime prevention and detection. It was this legitimate investigative function Officer McFadden was discharging when he decided to approach petitioner and his companions. He had observed Terry, Chilton, and Katz go through a series of acts, each of them perhaps innocent in itself, but which taken together warranted further investigation. The crux of this case, however, is not the propriety of Officer McFadden’s taking steps to investigate petitioner’s suspicious behavior, but rather, whether there was justification for McFadden’s invasion of Terry’s personal security by searching him for weapons in the course of that investigation. We are now concerned with more than the governmental interest in investigating crime; in addition, there is the more immediate interest of the police officer in taking steps to assure himself that the person with whom he is dealing is not armed with a weapon that could unexpectedly and fatally be used against him. Certainly it would be unreasonable to require that police officers take unnecessary risks in the performance of their duties. \[W]e cannot blind ourselves to 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. When an officer is justified in believing that the individual whose suspicious behavior he is investigating at close range is armed and presently dangerous to the officer or to others, it would appear to be clearly unreasonable to deny the officer the power to take necessary measures to determine whether the person is in fact carrying a weapon and to neutralize the threat of physical harm. We must still consider, however, the nature and quality of the intrusion on individual rights which must be accepted if police officers are to be conceded the right to search for weapons in situations where probable cause to arrest for crime is lacking. Even 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. Our evaluation of the proper balance that has to be struck in this type of case leads us to conclude that there must be a narrowly drawn authority to permit a reasonable search for weapons for the protection of the police officer, where he has reason to believe that he is dealing with an armed and dangerous individual, regardless of whether he has probable cause to arrest the individual for a crime. The officer need not be absolutely certain that the individual is armed; the issue is whether a reasonably prudent man in the circumstances would be warranted in the belief that his safety or that of others was in danger. And in determining whether the officer acted reasonably in such circumstances, due weight must be given, not to his inchoate and unparticularized suspicion or “hunch,” but to the specific reasonable inferences which he is entitled to draw from the facts in light of his experience. **IV** We must now examine the conduct of Officer McFadden in this case to determine whether his search and seizure of petitioner were reasonable, both at their inception and as conducted. He had observed Terry, together with Chilton and another man, acting in a manner he took to be preface to a “stick-up.” We think on the facts and circumstances Officer McFadden detailed before the trial judge a reasonably prudent man would have been warranted in believing petitioner was armed and thus presented a threat to the officer’s safety while he was investigating his suspicious behavior. The actions of Terry and Chilton were consistent with McFadden’s hypothesis that these men were contemplating a daylight robbery—which, it is reasonable to assume, would be likely to involve the use of weapons—and nothing in their conduct from the time he first noticed them until the time he confronted them and identified himself as a police officer gave him sufficient reason to negate that hypothesis. Thus, when Officer McFadden approached the three men gathered before the display window at Zucker’s store he had observed enough to make it quite reasonable to fear that they were armed; and nothing in their response to his hailing them, identifying himself as a police officer, and asking their names served to dispel that reasonable belief. We cannot say his decision at that point to seize Terry and pat his clothing for weapons was the product of a volatile or inventive imagination, or was undertaken simply as an act of harassment; the record evidences the tempered act of a policeman who in the course of an investigation had to make a quick decision as to how to protect himself and others from possible danger, and took limited steps to do so. We need not develop at length in this case, however, the limitations which the Fourth Amendment places upon a protective seizure and search for weapons. These limitations will have to be developed in the concrete factual circumstances of individual cases. Suffice it to note that such a search, unlike a search without a warrant incident to a lawful arrest, is not justified by any need to prevent the disappearance or destruction of evidence of crime. The sole justification of the search in the present situation is the protection of the police officer and others nearby, and it must therefore be confined in scope to an intrusion reasonably designed to discover guns, knives, clubs, or other hidden instruments for the assault of the police officer. The scope of the search in this case presents no serious problem in light of these standards. Officer McFadden patted down the outer clothing of petitioner and his two companions. He did not place his hands in their pockets or under the outer surface of their garments until he had felt weapons, and then he merely reached for and removed the guns. He never did invade Katz’ person beyond the outer surfaces of his clothes, since he discovered nothing in his patdown which might have been a weapon. Officer McFadden confined his search strictly to what was minimally necessary to learn whether the men were armed and to disarm them once he discovered the weapons. He did not conduct a general exploratory search for whatever evidence of criminal activity he might find. **V** We conclude that the revolver seized from Terry was properly admitted in evidence against him. At the time he seized petitioner and searched him for weapons, Officer McFadden had reasonable grounds to believe that petitioner was armed and dangerous, and it was necessary for the protection of himself and others to take swift measures to discover the true facts and neutralize the threat of harm if it materialized. The policeman carefully restricted his search to what was appropriate to the discovery of the particular items which he sought. Each case of this sort will, of course, have to be decided on its own facts. We merely hold today that where a police officer observes unusual conduct which leads him reasonably to conclude in light of his experience that criminal activity may be afoot and that the persons with whom he is dealing may be armed and presently dangerous, where in the course of investigating this behavior he identifies himself as a policeman and makes reasonable inquiries, and where nothing in the initial stages of the encounter serves to dispel his reasonable fear for his own or others’ safety, he is entitled for the protection of himself and others in the area to conduct a carefully limited search of the outer clothing of such persons in an attempt to discover weapons which might be used to assault him. Such a search is a reasonable search under the Fourth Amendment, and any weapons seized may properly be introduced in evidence against the person from whom they were taken. Mr. Justice DOUGLAS, dissenting. The opinion of the Court disclaims the existence of “probable cause.” If loitering were in issue and that was the offense charged, there would be “probable cause” shown. But the crime here is carrying concealed weapons; and there is no basis for concluding that the officer had “probable cause” for believing that that crime was being committed. Had a warrant been sought, a magistrate would, therefore, have been unauthorized to issue one, for he can act only if there is a showing of “probable cause.” We hold today that the police have greater authority to make a “seizure” and conduct a “search” than a judge has to authorize such action. We have said precisely the opposite over and over again. \[P]olice officers up to today have been permitted to effect arrests or searches without warrants only when the facts within their personal knowledge would satisfy the constitutional standard of probable cause. At the time of their “seizure” without a warrant they must possess facts concerning the person arrested that would have satisfied a magistrate that “probable cause” was indeed present. The term “probable cause” rings a bell of certainty that is not sounded by phrases such as “reasonable suspicion.” To give the police greater power than a magistrate is to take a long step down the totalitarian path. Perhaps such a step is desirable to cope with modern forms of lawlessness. But if it is taken, it should be the deliberate choice of the people through a constitutional amendment. There have been powerful hydraulic pressures throughout our history that bear heavily on the Court to water down constitutional guarantees and give the police the upper hand. That hydraulic pressure has probably never been greater than it is today. Yet if the individual is no longer to be sovereign, if the police can pick him up whenever they do not like the cut of his jib, if they can “seize” and “search” him in their discretion, we enter a new regime. The decision to enter it should be made only after a full debate by the people of this country. \* \* \* Selections from opinions in the next case, *United States v. Place*, were included in the assignment for Chapter 5. In that chapter, the case was presented to illustrate that dog sniffs in public places—in and of themselves—do not constitute searches. In this chapter, we return to the case to study what constitutes a permissible seizure of “effects.” Supreme Court of the United States **United States v. Raymond J. Place** Decided June 20, 1983 – [462 U.S. 696](https://supreme.justia.com/cases/federal/us/462/696/) Justice O’CONNOR delivered the opinion of the Court. This case presents the issue whether the Fourth Amendment prohibits law enforcement authorities from temporarily detaining personal luggage for exposure to a trained narcotics detection dog on the basis of reasonable suspicion that the luggage contains narcotics. Given the enforcement problems associated with the detection of narcotics trafficking and the minimal intrusion that a properly limited detention would entail, we conclude that the Fourth Amendment does not prohibit such a detention. On the facts of this case, however, we hold that the police conduct exceeded the bounds of a permissible investigative detention of the luggage. **I** Respondent Raymond J. Place’s behavior aroused the suspicions of law enforcement officers as he waited in line at the Miami International Airport to purchase a ticket to New York’s LaGuardia Airport. As Place proceeded to the gate for his flight, the agents approached him and requested his airline ticket and some identification. Place complied with the request and consented to a search of the two suitcases he had checked. Because his flight was about to depart, however, the agents decided not to search the luggage. Prompted by Place’s parting remark that he had recognized that they were police, the agents inspected the address tags on the checked luggage and noted discrepancies in the two street addresses. Further investigation revealed that neither address existed and that the telephone number Place had given the airline belonged to a third address on the same street. On the basis of their encounter with Place and this information, the Miami agents called Drug Enforcement Administration (DEA) authorities in New York to relay their information about Place. Two DEA agents waited for Place at the arrival gate at LaGuardia Airport in New York. There again, his behavior aroused the suspicion of the agents. After he had claimed his two bags and called a limousine, the agents decided to approach him. They identified themselves as federal narcotics agents, to which Place responded that he knew they were “cops” and had spotted them as soon as he had deplaned. One of the agents informed Place that, based on their own observations and information obtained from the Miami authorities, they believed that he might be carrying narcotics. After identifying the bags as belonging to him, Place stated that a number of police at the Miami Airport had surrounded him and searched his baggage. The agents responded that their information was to the contrary. The agents requested and received identification from Place—a New Jersey driver’s license, on which the agents later ran a computer check that disclosed no offenses, and his airline ticket receipt. When Place refused to consent to a search of his luggage, one of the agents told him that they were going to take the luggage to a federal judge to try to obtain a search warrant and that Place was free to accompany them. Place declined, but obtained from one of the agents telephone numbers at which the agents could be reached. The agents then took the bags to Kennedy Airport,1 where they subjected the bags to a “sniff test” by a trained narcotics detection dog. The dog reacted positively to the smaller of the two bags but ambiguously to the larger bag. Approximately 90 minutes had elapsed since the seizure of respondent’s luggage. Because it was late on a Friday afternoon, the agents retained the luggage until Monday morning, when they secured a search warrant from a magistrate for the smaller bag. Upon opening that bag, the agents discovered 1,125 grams of cocaine. Place was indicted for possession of cocaine with intent to distribute. In the District Court, Place moved to suppress the contents of the luggage seized from him at LaGuardia Airport. The District Court denied the motion. Place pleaded guilty to the possession charge, reserving the right to appeal the denial of his motion to suppress. On appeal of the conviction, the United States Court of Appeals for the Second Circuit reversed. We granted certiorari and now affirm. **II** In the ordinary case, the Court has viewed a seizure of personal property as *per se* unreasonable within the meaning of the Fourth Amendment unless it is accomplished pursuant to a judicial warrant issued upon probable cause and particularly describing the items to be seized. Where law enforcement authorities have probable cause to believe that a container holds contraband or evidence of a crime, but have not secured a warrant, the Court has interpreted the Amendment to permit seizure of the property, pending issuance of a warrant to examine its contents, if the exigencies of the circumstances demand it or some other recognized exception to the warrant requirement is present. In this case, the Government asks us to recognize the reasonableness under the Fourth Amendment of warrantless seizures of personal luggage from the custody of the owner on the basis of less than probable cause, for the purpose of pursuing a limited course of investigation, short of opening the luggage, that would quickly confirm or dispel the authorities’ suspicion. Specifically, we are asked to apply the principles of *Terry v. Ohio* to permit such seizures on the basis of reasonable, articulable suspicion, premised on objective facts, that the luggage contains contraband or evidence of a crime. In our view, such application is appropriate. The exception to the probable-cause requirement for limited seizures of the person recognized in *Terry* and its progeny rests on a balancing of the competing interests to determine the reasonableness of the type of seizure involved within the meaning of “the Fourth Amendment’s general proscription against unreasonable searches and seizures.” We must balance the nature and quality of the intrusion on the individual’s Fourth Amendment interests against the importance of the governmental interests alleged to justify the intrusion. When the nature and extent of the detention are minimally intrusive of the individual’s Fourth Amendment interests, the opposing law enforcement interests can support a seizure based on less than probable cause. We examine first the governmental interest offered as a justification for a brief seizure of luggage from the suspect’s custody for the purpose of pursuing a limited course of investigation. The Government contends that, where the authorities possess specific and articulable facts warranting a reasonable belief that a traveler’s luggage contains narcotics, the governmental interest in seizing the luggage briefly to pursue further investigation is substantial. We agree. Against this strong governmental interest, we must weigh the nature and extent of the intrusion upon the individual’s Fourth Amendment rights when the police briefly detain luggage for limited investigative purposes. On this point, respondent Place urges that the rationale for a *Terry* stop of the person is wholly inapplicable to investigative detentions of personality. Specifically, the *Terry* exception to the probable-cause requirement is premised on the notion that a *Terry*-type stop of the person is substantially less intrusive of a person’s liberty interests than a formal arrest. In the property context, however, Place urges, there are no degrees of intrusion. Once the owner’s property is seized, the dispossession is absolute. We disagree. The intrusion on possessory interests occasioned by a seizure of one’s personal effects can vary both in its nature and extent. The seizure may be made after the owner has relinquished control of the property to a third party or, as here, from the immediate custody and control of the owner. Moreover, the police may confine their investigation to an on-the-spot inquiry—for example, immediate exposure of the luggage to a trained narcotics detection dog—or transport the property to another location. Given the fact that seizures of property can vary in intrusiveness, some brief detentions of personal effects may be so minimally intrusive of Fourth Amendment interests that strong countervailing governmental interests will justify a seizure based only on specific articulable facts that the property contains contraband or evidence of a crime. In sum, we conclude that when an officer’s observations lead him reasonably to believe that a traveler is carrying luggage that contains narcotics, the principles of *Terry* and its progeny would permit the officer to detain the luggage briefly to investigate the circumstances that aroused his suspicion, provided that the investigative detention is properly limited in scope. The purpose for which respondent’s luggage was seized, of course, was to arrange its exposure to a narcotics detection dog. Obviously, if this investigative procedure is itself a search requiring probable cause, the initial seizure of respondent’s luggage for the purpose of subjecting it to the sniff test—no matter how brief—could not be justified on less than probable cause. \[The Court then held that “exposure of respondent’s luggage, which was located in a public place, to a trained canine—did not constitute a ‘search’ within the meaning of the Fourth Amendment.”] **III** We \[next] examine whether the agents’ conduct in this case was such as to place the seizure within the general rule requiring probable cause for a seizure or within *Terry’*s exception to that rule. The precise type of detention we confront here is seizure of personal luggage from the immediate possession of the suspect for the purpose of arranging exposure to a narcotics detection dog. Particularly in the case of detention of luggage within the traveler’s immediate possession, the police conduct intrudes on both the suspect’s possessory interest in his luggage as well as his liberty interest in proceeding with his itinerary. The person whose luggage is detained is technically still free to continue his travels or carry out other personal activities pending release of the luggage. Moreover, he is not subjected to the coercive atmosphere of a custodial confinement or to the public indignity of being personally detained. Nevertheless, such a seizure can effectively restrain the person since he is subjected to the possible disruption of his travel plans in order to remain with his luggage or to arrange for its return. Therefore, when the police seize luggage from the suspect’s custody, we think the limitations applicable to investigative detentions of the person should define the permissible scope of an investigative detention of the person’s luggage on less than probable cause. Under this standard, it is clear that the police conduct here exceeded the permissible limits of a *Terry*-type investigative stop. The length of the detention of respondent’s luggage alone precludes the conclusion that the seizure was reasonable in the absence of probable cause. \[I]n assessing the effect of the length of the detention, we take into account whether the police diligently pursue their investigation. We note that here the New York agents knew the time of Place’s scheduled arrival at LaGuardia, had ample time to arrange for their additional investigation at that location, and thereby could have minimized the intrusion on respondent’s Fourth Amendment interests. Thus, although we decline to adopt any outside time limitation for a permissible *Terry* stop, we have never approved a seizure of the person for the prolonged 90-minute period involved here and cannot do so on the facts presented by this case. Although the 90-minute detention of respondent’s luggage is sufficient to render the seizure unreasonable, the violation was exacerbated by the failure of the agents to accurately inform respondent of the place to which they were transporting his luggage, of the length of time he might be dispossessed, and of what arrangements would be made for return of the luggage if the investigation dispelled the suspicion. In short, we hold that the detention of respondent’s luggage in this case went beyond the narrow authority possessed by police to detain briefly luggage reasonably suspected to contain narcotics. **IV** We conclude that, under all of the circumstances of this case, the seizure of respondent’s luggage was unreasonable under the Fourth Amendment. Consequently, the evidence obtained from the subsequent search of his luggage was inadmissible, and Place’s conviction must be reversed. The judgment of the Court of Appeals, accordingly, is affirmed.
