Amdt4.4.4.1.1 Terry Stop and Frisks: Doctrine and Practice

Fourth Amendment:

The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.

Arrests are subject to the requirements of the Fourth Amendment, but the courts have followed the common law in upholding the right of police officers to take a person into custody without a warrant if they have probable cause to believe that the person to be arrested has committed a felony or a misdemeanor in their presence.1 Probable cause is, of course, the same standard required to be met in the issuance of an arrest warrant, and must be satisfied by conditions existing prior to the police officer’s stop, what is discovered thereafter not sufficing to establish probable cause retroactively.2 There are, however, instances when a police officer’s suspicions will have been aroused by someone’s conduct or manner, but probable cause for placing such a person under arrest will be lacking.3 In Terry v. Ohio,4 the Court, with only Justice Douglas dissenting, approved an on-the-street investigation by a police officer that involved patting down the subject of the investigation for weapons.

Terry arose when a police officer observed three individuals engaging in conduct which appeared to him, on the basis of training and experience, to be the casing of a store for a likely armed robbery. Upon approaching the men, identifying himself, and not receiving prompt identification, the officer seized one of the men, patted the exterior of his clothes, and discovered a gun. Chief Justice Warren for the Court wrote that the Fourth Amendment was applicable whenever a police officer accosts an individual and restrains his freedom to walk away.5 Because the warrant clause is necessarily and practically of no application to the type of on-the-street encounter present in Terry, the Chief Justice continued, the question was whether the policeman’s actions were reasonable. The test of reasonableness in this sort of situation is whether the police officer can point to specific and articulable facts which, taken together with rational inferences from those facts, would lead a neutral magistrate on review to conclude that a man of reasonable caution would be warranted in believing that possible criminal behavior was at hand and that both an investigative stop and a frisk was required.6 Because the conduct witnessed by the police officer reasonably led him to believe that an armed robbery was in prospect, he was as reasonably led to believe that the men were armed and probably dangerous and that his safety required a frisk. Because the object of the frisk is the discovery of dangerous weapons, 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.7

In a later case, the Court held that an officer may seize an object if, in the course of a weapons frisk, plain touch reveals the presence of the object, and the officer has probable cause to believe it is contraband.8 The Court viewed the situation as analogous to that covered by the plain view doctrine: obvious contraband may be seized, but a search may not be expanded to determine whether an object is contraband.9 Also impermissible is physical manipulation, without reasonable suspicion, of a bus passenger’s carry-on luggage stored in an overhead compartment.10

Terry did not rule on a host of problems, including the grounds that could permissibly lead an officer to momentarily stop a person on the street or elsewhere in order to ask questions rather than frisk for weapons, the right of the stopped individual to refuse to cooperate, and the permissible response of the police to that refusal. The Court provided a partial answer in 2004, when it upheld a state law that required a suspect to disclose his name in the course of a valid Terry stop.11 Questions about a suspect's identity are a routine and accepted part of many Terry stops, the Court explained.12

After Terry, the standard for stops for investigative purposes evolved into one of reasonable suspicion of criminal activity. That test permits some stops and questioning without probable cause in order to allow police officers to explore the foundations of their suspicions.13 Although it did not elaborate a set of rules to govern the application of the tests, the Court was initially restrictive in recognizing permissible bases for reasonable suspicion.14 Extensive intrusions on individual privacy, e.g., transportation to the station house for interrogation and fingerprinting, were invalidated in the absence of probable cause,15 although the Court has held that an uncorroborated, anonymous tip is insufficient basis for a Terry stop, and that there is no firearms exception to the reasonable suspicion requirement.16 More recently, however, the Court has taken less restrictive approaches.17

It took the Court some time to settle on a test for when a seizure has occurred, and the Court has recently modified its approach. The issue is of some importance, since it is at this point that Fourth Amendment protections take hold. The Terry Court recognized in dictum that not all personal intercourse between policemen and citizens involves ‘seizures’ of persons, and suggested that [o]nly when the officer, by means of physical force or show of authority, has in some way restrained the liberty of a citizen may we conclude that a ‘seizure’ has occurred.18 Years later Justice Stewart proposed a similar standard – that a person has been seized 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.19 A majority of the Justices subsequently endorsed this reasonable perception standard20 and applied it in several cases in which admissibility of evidence turned on whether a seizure of the person not justified by probable cause or reasonable suspicion had occurred prior to the uncovering of the evidence. No seizure occurred, for example, when INS agents seeking to identify unlawfully present aliens conducted workforce surveys within a garment factory; while some agents were positioned at exits, others systematically moved through the factory and questioned employees.21 This brief questioning, even with blocked exits, amounted to classic consensual encounters rather than Fourth Amendment seizures.22 The Court also ruled that no seizure had occurred when police in a squad car drove alongside a suspect who had turned and run down the sidewalk when he saw the squad car approach. Under the circumstances (no siren, flashing lights, display of a weapon, or blocking of the suspect’s path), the Court concluded, the police conduct would not have communicated to the reasonable person an attempt to capture or otherwise intrude upon [one’s] freedom of movement.23

Soon after, however, the Court departed from the Mendenhall reasonable-perception standard and adopted a more formalistic approach, holding that an actual chase with evident intent to capture did not amount to a seizure because the suspect had not complied with the officer’s order to halt. The Court in California v. Hodari D. wrote that Mendenhall stated a necessary but not a sufficient condition for a seizure of the person through show of authority.24 A Fourth Amendment seizure of the person, the Court determined, is the same as a common law arrest; there must be either application of physical force (or the laying on of hands), or submission to the assertion of authority.25 Indications are, however, that Hodari D. did not signal the end of the reasonable perception standard, but merely carved an exception applicable to chases and perhaps other encounters between suspects and police.

Later in the same term the Court ruled that the Mendenhall free-to-leave inquiry was misplaced in the context of a police sweep of a bus, but that a modified reasonable perception approach still governed.26 In conducting a bus sweep, aimed at detecting illegal drugs and their couriers, police officers typically board a bus during a stopover at a terminal and ask to inspect tickets, identification, and sometimes luggage of selected passengers. The Court did not focus on whether an arrest had taken place, as adherence to the Hodari D. approach would have required, but instead suggested that the appropriate inquiry is whether a reasonable person would feel free to decline the officers’ requests or otherwise terminate the encounter.27 When the person is seated on a bus and has no desire to leave, the Court explained, the degree to which a reasonable person would feel that he or she could leave is not an accurate measure of the coercive effect of the encounter.28

Officers must have articulable reasons or founded suspicions, derived from the totality of the circumstances. Based upon that whole picture the detaining officer must have a particularized and objective basis for suspecting the particular person stopped of criminal activity. Id. at 417–18. The inquiry is thus quite fact-specific. In the anonymous tip context, the same basic approach requiring some corroboration applies regardless of whether the standard is probable cause or reasonable suspicion; the difference is that less information, or less reliable information, can satisfy the lower standard.

Like the workers in that case [subjected to the INS ‘survey’ at their workplace], Bostick’s freedom of movement was restricted by a factor independent of police conduct – i.e., by his being a passenger on a bus. Id. See also United States v. Drayton, 536 U.S. 194 (2002), applying Bostick to uphold a bus search in which one officer stationed himself in the front of the bus and one in the rear, while a third officer worked his way from rear to front, questioning passengers individually. Under these circumstances, and following the arrest of his traveling companion, the defendant had consented to the search of his person.
