United States v. Watson, 423 U.S. 411 (1976)

Syllabus

A postal inspector received from an informant of known reliability a stolen credit card that respondent had given the informant to be used for their mutual advantage, and the inspector was told by the informant that respondent had agreed to furnish additional cards. At the inspector’s suggestion, a meeting was arranged between the informant and respondent for a few days later, which took place at a restaurant. Upon a prearranged signal from the informant that respondent had the additional cards, postal officers made a warrantless arrest of respondent, removed him from the restaurant, and gave him Miranda warnings. When a search of respondent’s person revealed no cards, a consented search of his nearby car (after respondent had been cautioned that the results could be used against him) revealed two additional cards in the names of other persons. Following an unsuccessful motion to suppress, these cards were used as evidence in respondent’s trial, which resulted in his conviction of possessing stolen mail. The Court of Appeals reversed, ruling that the Fourth Amendment prohibited use of that evidence because (1) notwithstanding probable cause for respondent’s arrest, the arrest was unconstitutional because the postal inspector had failed to secure an arrest warrant though he had time to do so, and (2) based on the totality of the circumstances (including the illegality of the arrest), respondent’s consent to the car search was coerced and thus, invalid.

Held:

1. The arrest of respondent, having been based on probable cause and made by postal officers acting in strict compliance with the governing statute and regulations, did not violate the Fourth Amendment. Pp.  423 U. S. 414-424.

2. Since the arrest comported with the Fourth Amendment, respondent’s consent to the car search was not, contrary to the holding of the Court of Appeals, the product of an illegal arrest, nor were there any other circumstances indicating that respondent’s consent was not his own “essentially free and unconstrained

United States v Sokolow, 490 U.S. 1 (1989)

Syllabus

Drug Enforcement Administration (DEA) agents stopped respondent upon his arrival at Honolulu International Airport. The agents found 1,063 grams of cocaine in his carry-on luggage. When respondent was stopped, the agents knew, inter alia, that (1) he paid $2,100 for two round-trip plane tickets from a roll of $20 bills; (2) he traveled under a name that did not match the name under which his telephone number was listed; (3) his original destination was Miami, a source city for illicit drugs; (4) he stayed in Miami for only 48 hours, even though a round-trip flight from Honolulu to Miami takes 20 hours; (5) he appeared nervous during his trip; and (6) he checked none of his luggage. Respondent was indicted for possession with intent to distribute cocaine. The District Court denied his motion to suppress the evidence, finding that the stop was justified by a reasonable suspicion that he was engaged in criminal activity, as required by the Fourth Amendment. The Court of Appeals disagreed and reversed respondent’s conviction, applying a two-part test for determining reasonable suspicion. First, ruled the court, at least one fact describing “ongoing criminal activity” — such as the use of an alias or evasive movement through an airport — was always necessary to support a reasonable suspicion finding. Second, “probabilistic” facts describing “personal characteristics” of drug couriers — such as the cash payment for tickets, a short trip to a major source city for drugs, nervousness, type of attire, and unchecked luggage — were only relevant if there was evidence of “ongoing criminal activity” and the Government 

Page 490 U. S. 2

offered “[e]mpirical documentation” that the combination of facts at issue did not describe the behavior of “significant numbers of innocent persons.” The Court of Appeals held the agents’ stop impermissible, because there was no evidence of ongoing criminal behavior in this case.

Held: On the facts of this case, the DEA agents had a reasonable suspicion that respondent was transporting illegal drugs when they stopped him. Pp.  490 U. S. 7-11.

(a) Under Terry v. Ohio, 392 U. S. 1,  392 U. S. 30, the police can stop and briefly detain a person for investigative purposes if they have a reasonable suspicion supported by articulable facts that criminal activity “may be afoot,” even if they lack probable cause under the Fourth Amendment. Reasonable suspicion entails some minimal level of objective justification for making a stop — that is, something more than an inchoate and unparticularized suspicion or “hunch,” but less than the level of suspicion required for probable cause. P.  490 U. S. 7.

(b) The Court of Appeals’ two-part test creates unnecessary difficulty in dealing with one of the relatively simple concepts embodied in the Fourth Amendment. Under this Court’s decisions, the totality of the circumstances must be evaluated to determine the probability, rather than the certainty, of criminal conduct.  United States v. Cortez, 449 U. S. 411,  449 U. S. 417. The Court of Appeals’ test draws an unnecessarily sharp line between types of evidence, the probative value of which varies only in degree. While traveling under an alias or taking an evasive path through an airport may be highly probative, neither type of evidence has the sort of ironclad significance attributed to it by the Court of Appeals, because there are instances in which neither factor would reflect ongoing criminal activity. On the other hand, the test’s “probabilistic” factors also have probative significance. Paying $2,100 in cash for airline tickets from a roll of $20 bills containing nearly twice that amount is not ordinary conduct for most business travelers or vacationers. The evidence that respondent was traveling under an alias, although not conclusive, was sufficient to warrant consideration. Of similar effect is the probability that few Honolulu residents travel for 20 hours to spend 48 hours in Miami during July. Thus, although each of these factors is not, by itself, proof of illegal conduct, and is quite consistent with innocent travel, taken together, they amount to reasonable suspicion that criminal conduct was afoot. Pp.  490 U. S. 7-10.

(c) The fact that the agents believed that respondent’s behavior was consistent with one of the DEA’s “drug courier profiles” does not alter this analysis, because the factors in question have evidentiary significance regardless of whether they are set forth in a “profile.” P.  490 U. S. 10.

(d) The reasonableness of the decision to stop does not, as respondent contends, turn upon whether the police used the least intrusive means 

Page 490 U. S. 3

available to verify or dispel their suspicions. Such a rule would unduly hamper the officers’ ability to make on-the-spot decisions — here, respondent was about to enter a taxicab — and would require courts to indulge in unrealistic second-guessing.  Florida v. Royer, 460 U. S. 491,  460 U. S. 495, distinguished. Pp.  490 U. S. 10-11.

United States v. Sharpe, 470 U.S. 675 (1985)

Syllabus

A Drug Enforcement Administration (DEA) agent, while patrolling a highway in an area under surveillance for suspected drug trafficking, noticed an apparently overloaded pickup truck with an attached camper traveling in tandem with a Pontiac. Respondent Savage was driving the truck, and respondent Sharpe was driving the Pontiac. After following the two vehicles for about 20 miles, the agent decided to make an “investigative stop,” and radioed the South Carolina State Highway Patrol for assistance. An officer responded, and he and the DEA agent continued to follow the two vehicles. When they attempted to stop the vehicles, the Pontiac pulled over to the side of the road, but the truck continued on, pursued by the state officer. After identifying himself and obtaining identification from Sharpe, the DEA agent attempted to radio the State Highway Patrol officer. The DEA agent was unable to contact the state officer to see if he had stopped the truck, so he radioed the local police for help. In the meantime, the state officer had stopped the truck, questioned Savage, and told him that he would be held until the DEA agent arrived. The agent, who had left the local police with the Pontiac, arrived at the scene approximately 15 minutes after the truck had been stopped. After confirming his suspicion that the truck was overloaded and upon smelling marihuana, the agent opened the rear of the camper without Savage’s permission and observed a number of burlap-wrapped bales resembling bales of marihuana that the agent had seen in previous investigations. The agent then placed Savage under arrest and, returning to the Pontiac, also arrested Sharpe. Chemical tests later showed that the bales contained marihuana. Respondents were charged with federal drug offenses, and, after the District Court denied their motion to suppress the contraband, were convicted. The Court of Appeals reversed, holding that, because the investigative stops failed to meet the Fourth Amendment’s requirement of brevity governing detentions on less than probable cause, the marihuana should have been suppressed as the fruit of unlawful seizures.

Held: The detention of Savage clearly met the Fourth Amendment’s standard of reasonableness. Pp.  470 U. S. 682-688.

(a) In evaluating the reasonableness of an investigative stop, this Court examines

“whether the officer’s action was justified at its inception, and whether it was reasonably related in scope to the circumstances 

Page 470 U. S. 676

which justified the interference in the first place.”

Terry v. Ohio, 392 U. S. 1,  392 U. S. 20. As to the first part of the inquiry, the Court of Appeals assumed that the officers had an articulable and reasonable suspicion that respondents were engaged in marihuana trafficking, and the record abundantly supports that assumption, given the circumstances when the officers attempted to stop the Pontiac and the truck. As to the second part of the inquiry, while the brevity of an investigative detention is an important factor in determining whether the detention is unreasonable, courts must also consider the purposes to be served by the stop, as well as the time reasonably needed to effectuate those purposes. The Court of Appeals’ decision would effectively establish a per se rule that a 20-minute detention is too long to be justified under the Terry doctrine. Such a result is clearly and fundamentally at odds with this Court’s approach in this area. Pp. 682-686.

(b) In assessing whether a detention is too long in duration to be justified as an investigative stop, it is appropriate to examine whether the police diligently pursued a means of investigation that was likely to confirm or dispel their suspicions quickly, during which time it was necessary to detain the defendant. Here, the DEA agent diligently pursued his investigation, and clearly no delay unnecessary to the investigation was involved. Pp.  470 U. S. 686-688.

United States v. Santana, 427 U.S. 38 (1976)

Syllabus

On the basis of information that respondent Santana had in her possession marked money used to make a heroin “buy” arranged by an undercover agent, police officers went to Santana’s house where she was standing in the doorway holding a paper bag, but, as the officers approached, she retreated into the vestibule of her house, where they caught her. When she tried to escape, envelopes containing what was later determined to be heroin fell to the floor from the paper bag, and she was found to have been carrying some of the marked money on her person. Respondent Alejandro, who had been sitting on the front steps, was caught when he tried to make off with the dropped envelopes of heroin. After their indictment for possessing heroin with intent to distribute, respondents moved to suppress the heroin and marked money. The District Court granted the motion on the ground that, although the officers had probable cause to make the arrests, Santana’s retreat into the vestibule did not justify a warrantless entry into the house on the ground of “hot pursuit.” The Court of Appeals affirmed.

Held:

1. Santana, while standing in the doorway of her house, was in a “public place” for purposes of the Fourth Amendment, since she was not in an area where she had any expectation of privacy, and was not merely visible to the public, but was exposed to public view, speech, hearing, and touch as if she had been standing completely outside her house. Thus, when the police, who concededly had probable cause to do so, sought to arrest her, they merely intended to make a warrantless arrest in a public place upon probable cause, and did not violate the Fourth Amendment.  United States v. Watson, 423 U. S. 411 . P.  427 U. S. 42

2. By retreating into a private place, Santana could not defeat an otherwise proper arrest that had been set in motion in a public place. Since there was a need to act quickly to prevent destruction of evidence, there was a true “hot pursuit,” which need not be an extended hue and cry “in and about [the] public streets,” and thus a warrantless entry to make the arrest was 

Page 427 U. S. 39

justified, Warden v. Hayden, 387 U. S. 294, as was the search incident to that arrest. Pp.  427 U. S. 42-43.

United States v. Ross, 456 U.S. 798 (1982)

Syllabus

Acting on information from an informant that a described individual was selling narcotics kept in the trunk of a certain car parked at a specified location, District of Columbia police officers immediately drove to the location, found the car there, and, a short while later, stopped the car and arrested the driver (respondent), who matched the informant’s description. One of the officers opened the car’s trunk, found a closed brown paper bag, and after opening the bag, discovered glassine bags containing white powder (later determined to be heroin). The officer then drove the car to headquarters, where another warrantless search of the trunk revealed a zippered leather pouch containing cash. Respondent was subsequently convicted of possession of heroin with intent to distribute — the heroin and currency found in the searches having been introduced in evidence after respondent’s pretrial motion to suppress the evidence had been denied. The Court of Appeals reversed, holding that, while the officers had probable cause to stop and search respondent’s car — including its trunk — without a warrant, they should not have opened either the paper bag or the leather pouch found in the trunk without first obtaining a warrant.

Held: Police officers who have legitimately stopped an automobile and who have probable cause to believe that contraband is concealed somewhere within it may conduct a warrantless search of the vehicle that is as thorough as a magistrate could authorize by warrant. Pp.  456 U. S. 804-825.

(a) The “automobile exception” to the Fourth Amendment’s warrant requirement established in Carroll v. United States, 267 U. S. 132, applies to searches of vehicles that are supported by probable cause to believe that the vehicle contains contraband. In this class of cases, a search is not unreasonable if based on objective facts that would justify the issuance of a warrant, even though a warrant has not actually been obtained. Pp.  456 U. S. 804-809.

(b) However, the rationale justifying the automobile exception does not apply so as to permit a warrantless search of any movable container that is believed to be carrying an illicit substance and that is found in a public place even when the container is placed in a vehicle (not otherwise believed to be carrying contraband).  United States v. Chadwick, 433 U. S. 1; Arkansas v. Sanders, 442 U. S. 753. Pp.  456 U. S. 809-814. 

Page 456 U. S. 799

(c) Where police officers have probable cause to search an entire vehicle, they may conduct a warrantless search of every part of the vehicle and its contents, including all containers and packages, that may conceal the object of the search. The scope of the search is not defined by the nature of the container in which the contraband is secreted. Rather, it is defined by the object of the search and the places in which there is probable cause to believe that it may be found. For example, probable cause to believe that undocumented aliens are being transported in a van will not justify a warrantless search of a suitcase. Pp.  456 U. S. 817-824.

(d) The doctrine of stare decisis does not preclude rejection here of the holding in Robbins v. California, 453 U. S. 420, and some of the reasoning in Arkansas v. Sanders, supra. Pp.  456 U. S. 824-825.

United States v. Robinson, 414 U.S. 218 (1973)

Syllabus

Having, as a result of a previous check of respondent’s operator’s permit, probable cause to arrest respondent for driving while his license was revoked, a police officer made a full custody arrest of respondent for such offense. In accordance with prescribed procedures, the officer made a search of respondent’s person, in the course of which he found in a coat pocket a cigarette package containing heroin. The heroin was admitted into evidence at the District Court trial, which resulted in respondent’s conviction for a drug offense. The Court of Appeals reversed on the ground that the heroin had been obtained as a result of a search in violation of the Fourth Amendment.

Held: In the case of a lawful custodial arrest, a full search of the person is not only an exception to the warrant requirement of the Fourth Amendment, but is also a “reasonable” search under that Amendment. Pp.  414 U. S. 224-237.

(a) A search incident to a valid arrest is not limited to a frisk of the suspect’s outer clothing and removal of such weapons as the arresting officer may, as a result of such frisk, reasonably believe and ascertain that the suspect has in his possession, and the absence of probable fruits or further evidence of the particular crime for which the arrest is made does not narrow the standards applicable to such a search.  Terry v. Ohio,392 U. S. 1, distinguished. Pp.  414 U. S. 227-229; 23235.

(b) A custodial arrest of a suspect based on probable cause is a reasonable intrusion under the Fourth Amendment and, a search incident to the arrest requires no additional justification, such as the probability in a particular arrest situation that weapons or evidence would, in fact, be found upon the suspect’s person; and whether or not there was present one of the reasons supporting the authority for a search of the person incident to a lawful arrest need not be litigated in each case. P.  414 U. S. 235.

(c) Since the custodial arrest here gave rise to the authority 

Page 414 U. S. 219

to search, it is immaterial that the arresting officer did not fear the respondent or suspect that he was armed. Pp.  414 U. S. 236-237.

United States v. Place, 462 U.S. 696 (1983)

Syllabus

When respondent’s behavior aroused the suspicion of law enforcement officers as he waited in line at the Miami International Airport to purchase a ticket to New York’s La Guardia Airport, the officers approached respondent and requested and received identification. Respondent consented to a search of the two suitcases he had checked, but, because his flight was about to depart, the officers decided not to search the luggage. The officers then found some discrepancies in the address tags on the luggage and called Drug Enforcement Administration (DEA) authorities in New York to relay this information. Upon respondent’s arrival at La Guardia Airport, two DEA agents approached him, said that they believed he might be carrying narcotics, and asked for and received identification. When respondent refused to consent to a search of his luggage, one of the agents told him that they were going to take it to a federal judge to obtain a search warrant. The agents then took the luggage to Kennedy Airport where it was subjected to a “sniff test” by a trained narcotics detection dog which reacted positively to one of the suitcases. At this point, 90 minutes had elapsed since the seizure of the luggage. Thereafter, the agents obtained a search warrant for that suitcase and, upon opening it, discovered cocaine. Respondent was indicted for possession of cocaine with intent to distribute, and the District Court denied his motion to suppress the contents of the suitcase. He pleaded guilty to the charge and was convicted, but reserved the right to appeal the denial of his motion to suppress. The Court of Appeals reversed, holding that the prolonged seizure of respondent’s luggage exceeded the limits of the type of investigative stop permitted by Terry v. Ohio, 392 U. S. 1, and hence amounted to a seizure without probable cause in violation of the Fourth Amendment.

Held: Under the circumstances, the seizure of respondent’s luggage violated the Fourth Amendment. Accordingly, the evidence obtained from the subsequent search of the luggage was inadmissible, and respondent’s conviction must be reversed. Pp.  462 U. S. 700-710.

(a) 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 permit the officer to detain the luggage temporarily to investigate the circumstances that aroused the officer’s suspicion, 

Page 462 U. S. 697

provided that the investigative detention is properly limited in scope. Pp.  462 U. S. 700-706.

(b) The investigative procedure of subjecting luggage to a “sniff test” by a well-trained narcotics detection dog does not constitute a “search” within the meaning of the Fourth Amendment. Pp.  462 U. S. 706-707.

(c) When the police seize luggage from the suspect’s custody, the limitations applicable to investigative detentions of the person should define the permissible scope of an investigative detention of the luggage on less than probable cause. Under this standard, 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. This Fourth Amendment violation was exacerbated by the DEA agents’ failure to inform respondent accurately 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. Pp.  462 U. S. 707-710.

United States v. Mendenhall, 446 U.S. 544 (1980)

Syllabus

Respondent, prior to trial in Federal District Court on a charge of possessing heroin with intent to distribute it, moved to suppress the introduction in evidence of the heroin on the ground that it had been acquired through an unconstitutional search and seizure by Drug Enforcement Administration (DEA) agents. At the hearing on the motion, it was established that, when respondent arrived at the Detroit Metropolitan Airport on a flight from Los Angeles, two DEA agents, observing that her conduct appeared to be characteristic of persons unlawfully carrying narcotics, approached her as she was walking through the concourse, identified themselves as federal agents, and asked to see her identification and airline ticket. After respondent produced her driver’s license, which was in her name, and her ticket, which was issued in another name, the agents questioned her briefly as to the discrepancy and as to how long she had been in California. After returning the ticket and driver’s license to her, one of the agents asked respondent if she would accompany him to the airport DEA office for further questions, and respondent did so. At the office, the agent asked respondent if she would allow a search of her person and handbag and told her that she had the right to decline the search if she desired. She responded: “Go ahead,” and handed her purse to the agent. A female police officer, who arrived to conduct the search of respondent’s person, also asked respondent if she consented to the search, and respondent replied that she did. When the policewoman explained that respondent would have to remove her clothing, respondent stated that she had a plane to catch, and was assured that, if she was carrying no narcotics, there would be no problem. Respondent began to disrobe without further comment, and took from her undergarments two packages, one of which appeared to contain heroin, and handed them to the policewoman. Respondent was then arrested for possessing heroin. The District Court denied the motion to suppress, concluding that the agents’ conduct in initially approaching the respondent and asking to see her ticket and identification was a permissible investigative stop, based on facts justifying a suspicion of criminal activity, that respondent had accompanied the agents to the DEA office voluntarily, and that respondent voluntarily consented to the 

Page 446 U. S. 545

search in the DEA office. Respondent was convicted after trial, but the Court of Appeals reversed, finding that respondent had not validly consented to the search.

Held: The judgment is reversed and the case is remanded. Pp.  446 U. S. 550-560;  446 U. S. 560-566.

596 F.2d 706, reversed and remanded.

MR. JUSTICE STEWART delivered the opinion of the Court with respect to parts I, II-B, II-C, and III, concluding:

1. Respondent’s Fourth Amendment rights were not violated when she went with the agents from the concourse to the DEA office. Whether her consent to accompany the agents was in fact voluntary or was the product of duress or coercion is to be determined by the totality of all the circumstances. Under this test, the evidence — including evidence that respondent was not told that she had to go to the office, but was simply asked if she would accompany the officers, and that there were neither threats nor any show of force — was plainly adequate to support the District Court’s finding that respondent voluntarily consented to accompany the officers. The facts that the respondent was 22 years old, had not been graduated from high school, and was a Negro accosted by white officers, while not irrelevant, were not decisive.  Cf. Schneckloth v. Bustamonte, 412 U. S. 218. Pp.  446 U. S. 557-558.

2. The evidence also clearly supported the District Court’s view that respondent’s consent to the search of her person at the DEA office was freely and voluntarily given. She was plainly capable of a knowing consent, and she was twice expressly told by the officers that she was free to withhold consent, and only thereafter explicitly consented to the search. The trial court was entitled to view her statement, made when she was told that the search would require the removal of her clothing, that “she had a plane to catch” as simply an expression of concern that the search be conducted quickly, not as indicating resistance to the search. Pp. 446 U. S. 558-559.

MR. JUSTICE STEWART, joined by MR. JUSTICE REHNQUIST, concluded in Part II-A, that no “seizure” of respondent, requiring objective justification, occurred when the agents approached her on the concourse and asked questions of her. A person has been “seized” within the meaning of the Fourth Amendment only if, in view of all of the circumstances surrounding the incident, a reasonable person would have believed that he was not free to leave, and as long as the person to whom questions are put remains free to disregard the questions and walk away, there has been no intrusion upon that person’s liberty or privacy as would require some particularized and objective justification. Nothing in the record suggests that respondent had any objective reason to believe that 

Page 446 U. S. 546

she was not free to end the conversation in the concourse and proceed on her way. Pp.  446 U. S. 551-557.

MR. JUSTICE POWELL, joined by THE CHIEF JUSTICE and MR. JUSTICE BLACKMUN, concluded that the question whether the DEA agents “seized” respondent within the meaning of the Fourth Amendment should not be reached, because neither of the courts below considered the question; and that, assuming that the stop did constitute a seizure, the federal agents, in light of all the circumstances, had reasonable suspicion that respondent was engaging in criminal activity and, therefore, did not violate the Fourth Amendment by stopping her for routine questioning. Pp.  446 U. S. 560-566.

United States v. Matlock, 415 U.S. 164 (1974)

Syllabus

Respondent was arrested in the front yard of a house in which he lived along with a Mrs. Graff (daughter of the lessees) and others. The arresting officers, who did not ask him which room he occupied or whether he would consent to a search, were then admitted to the house by Mrs. Graff and, with her consent but without a warrant, searched the house, including a bedroom, which Mrs. Graff told them was jointly occupied by respondent and herself, and in a closet of which the officers found and seized money. Respondent was indicted for bank robbery, and moved to suppress the seized money as evidence. The District Court held that, where consent by a third person is relied upon as justification for a search, the Government must show, inter alia, not only that it reasonably appeared to the officers that the person had authority to consent, but also that the person had actual authority to permit the search, and that the Government had not satisfactorily proved that Mrs. Graff had such authority. Although Mrs. Graff’s statements to the officers that she and respondent occupied the same bedroom were deemed admissible to prove the officers’ good faith belief, they were held to be inadmissible extrajudicial statements to prove the truth of the facts therein averred, and the same was held to be true of statements by both Mrs. Graff and respondent that they were married, which was not the case. The Court of Appeals affirmed.

Held:

1. When the prosecution seeks to justify a warrantless search by proof of voluntary consent, it is not limited to proof that consent was given by the defendant, but may show that permission to search was obtained from a third party who possessed common authority over or other sufficient relationship to the premises or effects sought to be inspected. Pp.  415 U. S. 169-172.

2. It was error to exclude from evidence at the suppression hearings Mrs. Graff’s out-of-court statements respecting the joint occupancy of the bedroom, as well as the evidence that both respondent and Mrs. Graff had represented themselves as husband and wife. Pp.  415 U. S. 172-177. 

Page 415 U. S. 165

(a) There is no automatic rule against receiving hearsay evidence in suppression hearings (where the trial court itself can accord such evidence such weight as it deems desirable), and under the circumstances here, where the District Court as satisfied that Mrs. Graff’s out-of-court statements had, in fact, been made and nothing in the record raised doubts about their truthfulness, there was no apparent reason to exclude the declarations in the course of resolving the issues raised at the suppression hearings. Pp.  415 U. S. 172-176.

(b) Mrs. Graff’s statements were against her penal interest, since extramarital cohabitation is a state crime. Thus, they carried their own indicia of reliability and should have been admitted as evidence at the suppression hearings, even if they would not have been admissible at respondent’s trial. Pp.  415 U. S. 176-177.

3. Although, given the admissibility of the excluded statements, the Government apparently sustained its burden of proof as to Mrs. Graff’s authority to consent to the search, the District Court should reconsider the sufficiency of the evidence in light of this Court’s opinion. Pp.  415 U. S. 177-178.

United States v. Johns, 469 U.S. 478 (1985)

CERTIORARI TO THE UNITED STATES COURT OF APPEALS

FOR THE NINTH CIRCUIT

Syllabus

Pursuant to an investigation of a suspected drug smuggling operation, United States Customs officers, by ground and air surveillance, observed two pickup trucks as they traveled to a remote private airstrip in Arizona and the arrival and departure there of two small airplanes. The officers smelled the odor of marihuana as they approached the trucks and saw in the back of the trucks packages wrapped in dark green plastic and sealed with tape, a common method of packaging marihuana. After arresting certain of the respondents at the airstrip, the officers took the trucks back to Drug Enforcement Administration (DEA) headquarters, and the packages were then placed in a DEA warehouse. Three days after the packages were seized from the trucks, Government agents, without obtaining a search warrant, opened some of the packages and took samples that later proved to be marihuana. Before trial on federal drug charges, the District Court granted the respondents’ motion to suppress the marihuana, and the Court of Appeals affirmed, concluding, inter alia, that United States v. Ross, 456 U. S. 798 — which held that, if police officers have probable cause to search a lawfully stopped vehicle, they may conduct a warrantless search of any containers found inside that may conceal the object of the search — did not authorize the warrantless search of the packages three days after they were removed from the trucks.

United States v. Chadwick, 433 U.S. 1 (1977)

Syllabus

When respondents arrived by train in Boston from San Diego, they were arrested at their waiting automobile by federal narcotics agents, who had been alerted that respondents were possible drug traffickers. A double-locked footlocker, which respondents had transported on the train and which the agents had probable cause to believe contained narcotics, had been loaded in the trunk of the automobile. Respondents, together with the automobile and footlocker, which was admittedly under the agents’ exclusive control, were then taken to the Federal Building in Boston. An hour and a half after the arrests, the agents opened the footlocker without respondents’ consent or a search warrant, and found large amounts of marihuana in it. Respondents were subsequently indicted for possession of marihuana with intent to distribute it. The District Court granted their pretrial motion to suppress the marihuana obtained from the footlocker, holding that warrantless searches are per se unreasonable under the Fourth Amendment unless they fall within some established exception to the warrant requirement, and that the footlocker search was not justified under either the “automobile exception” or as a search incident to a lawful arrest; the Court of Appeals affirmed.

Held: Respondents were entitled to the protection of the Warrant Clause of the Fourth Amendment, with the evaluation 

Page 433 U. S. 2

of a neutral magistrate, before their privacy interests in the contents of the footlocker were invaded. Pp.  433 U. S. 6-16.

(a) A fundamental purpose of the Fourth Amendment is to safeguard individuals from unreasonable government invasions of legitimate privacy interests, and not simply those interests inside the four walls of the home. Pp.  433 U. S. 6-11.

(b) By placing personal effects inside a double-locked footlocker, respondents manifested an expectation that the contents would remain free from public examination, and, no less than one who locks the doors of his home against intruders, one who safeguards his personal possessions in this manner is due the protection of the Fourth Amendment’s Warrant Clause; since there was no exigency calling for an immediate search, it was unreasonable for the Government to conduct the search without the safeguards a judicial warrant provides. P.  433 U. S. 11.

(c) The footlocker search was not justified under the “automobile exception,” since a person’s expectations of privacy in personal luggage are substantially greater than in an automobile. In this connection, the footlocker’s mobility did not justify dispensing with a search warrant, because, once the federal agents had seized the footlocker at the railroad station and safely transferred it to the Federal Building under their exclusive control, there was not the slightest danger that it or its contents could have been removed before a valid search warrant could be obtained. Pp.  433 U. S. 11-13.

(d) Nor was the footlocker search justified as a search incident to a lawful arrest, where the search was remote in time or place from the arrest and no exigency existed, the search having been conducted more than an hour after the federal agents had gained exclusive control of the footlocker and long after respondents were securely in custody. Pp.  433 U. S. 14-16.

532 F.2d 773, affirmed.

Terry v. Ohio, 392 U.S. 1 (1968)

Syllabus

A Cleveland detective (McFadden), on a downtown beat which he had been patrolling for many years, observed two strangers (petitioner and another man, Chilton) on a street corner. He saw them proceed alternately back and forth along an identical route, pausing to stare in the same store window, which they did for a total of about 24 times. Each completion of the route was followed by a conference between the two on a corner, at one of which they were joined by a third man (Katz) who left swiftly. Suspecting the two men of “casing a job, a stick-up,” the officer followed them and saw them rejoin the third man a couple of blocks away in front of a store. The officer approached the three, identified himself as a policeman, and asked their names. The men “mumbled something,” whereupon McFadden spun petitioner around, patted down his outside clothing, and found in his overcoat pocket, but was unable to remove, a pistol. The officer ordered the three into the store. He removed petitioner’s overcoat, took out a revolver, and ordered the three to face the wall with their hands raised. He patted down the outer clothing of Chilton and Katz and seized a revolver from Chilton’s outside overcoat pocket. He did not put his hands under the outer garments of Katz (since he discovered nothing in his pat-down which might have been a weapon), or under petitioner’s or Chilton’s outer garments until he felt the guns. The three were taken to the police station. Petitioner and Chilton were charged with carrying 

Page 392 U. S. 2

concealed weapons. The defense moved to suppress the weapons. Though the trial court rejected the prosecution theory that the guns had been seized during a search incident to a lawful arrest, the court denied the motion to suppress and admitted the weapons into evidence on the ground that the officer had cause to believe that petitioner and Chilton were acting suspiciously, that their interrogation was warranted, and that the officer, for his own protection, had the right to pat down their outer clothing having reasonable cause to believe that they 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. Petitioner and Chilton were found guilty, an intermediate appellate court affirmed, and the State Supreme Court dismissed the appeal on the ground that “no substantial constitutional question” was involved.

Held:

1. The Fourth Amendment right against unreasonable searches and seizures, made applicable to the States by the Fourteenth Amendment, “protects people, not places,” and therefore applies as much to the citizen on the streets as well as at home or elsewhere. Pp.  392 U. S. 8-9.

2. The issue in this case is not the abstract propriety of the police conduct, but the admissibility against petitioner of the evidence uncovered by the search and seizure. P.  392 U. S. 12.

3. The exclusionary rule cannot properly be invoked to exclude the products of legitimate and restrained police investigative techniques, and this Court’s approval of such techniques should not discourage remedies other than the exclusionary rule to curtail police abuses for which that is not an effective sanction. Pp.  392 U.S. 13-15.

4. The Fourth Amendment applies to “stop and frisk” procedures such as those followed here. Pp.  392 U. S. 16-20.

(a) Whenever a police officer accosts an individual and restrains his freedom to walk away, he has “seized” that person within the meaning of the Fourth Amendment. P.  392 U. S. 16.

(b) A careful exploration of the outer surfaces of a person’s clothing in an attempt to find weapons is a “search” under that Amendment. P.  392 U. S. 16.

5. Where a reasonably prudent officer is warranted in the circumstances of a given case in believing that his safety or that of others is endangered, he may make a reasonable search for weapons of the person believed by him to be armed and dangerous 

Page 392 U. S. 3

regardless of whether he has probable cause to arrest that individual for crime or the absolute certainty that the individual is armed. Pp.  392 U. S. 20-27.

(a) Though the police must, whenever practicable, secure a warrant to make a search and seizure, that procedure cannot be followed where swift action based upon on-the-spot observations of the officer on the beat is required. P.  392 U. S. 20.

(b) The reasonableness of any particular search and seizure must be assessed in light of the particular circumstances against the standard of whether a man of reasonable caution is warranted in believing that the action taken was appropriate. Pp.  392 U. S. 21-22.

(c) The officer here was performing a legitimate function of investigating suspicious conduct when he decided to approach petitioner and his companions. P.  392 U. S. 22.

(d) An officer justified in believing that an individual whose suspicious behavior he is investigating at close range is armed may, to neutralize the threat of physical harm, take necessary measures to determine whether that person is carrying a weapon. P.  392 U. S. 24.

(e) A search for weapons in the absence of probable cause to arrest must be strictly circumscribed by the exigencies of the situation. Pp.  392 U. S. 25-26.

(f) An officer may make an intrusion short of arrest where he has reasonable apprehension of danger before being possessed of information justifying arrest. Pp.  392 U. S. 26-27.

6. The officer’s protective seizure of petitioner and his companions and the limited search which he made were reasonable, both at their inception and as conducted. Pp.  392 U. S. 27-30.

(a) The actions of petitioner and his companions were consistent with the officer’s hypothesis that they were contemplating a daylight robbery and were armed. P.  392 U. S. 28.

(b) The officer’s search was confined to what was minimally necessary to determine whether the men were armed, and the intrusion, which was made for the sole purpose of protecting himself and others nearby, was confined to ascertaining the presence of weapons. Pp.  392 U. S. 29-30.

7. The revolver seized from petitioner was properly admitted into evidence against him, since the search which led to its seizure was reasonable under the Fourth Amendment. Pp.  392 U. S. 30-31.

Affirmed.
