Police officers in various jurisdictions have power to search members of the public, for example, for weapons, drugs and stolen property. [1] This article concerns searches of members of the public who have not been arrested and who are not held in detention. For search powers in relation to those persons see Search on arrest and Searches in detention. For searches of property, rather than people, see search and seizure.
Police powers in England and Wales, allowing police officers to search members of the public for weapons, drugs, stolen property, terrorism-related evidence or evidence of other crimes are known as stop and search powers. [2]
Searches in the United States are governed by the Fourth Amendment to the U.S. Constitution, which generally requires that the police obtain a warrant before a search is legally permissible. However, certain exceptions to the warrant requirement exist.
After stopping a person based upon the reasonable belief that the person might be engaged in unlawful activity, or following a routine encounter such as a traffic stop, the police in the United States may perform a cursory search of the persons outer clothing for their own safety. Terry v. Ohio. [3] However, unless the object is reasonably identified by feel as a possible weapon or contraband, they may not remove objects from pockets, as that would constitute a search. Minnesota v. Dickerson. [4] When performing a pat-down following a Terry stop that results in the officer identifying a weapon by feel, a police officer is allowed to remove the weapon from the person's clothing. [3]
The Fourth Amendment to the United States Constitution is part of the Bill of Rights. It prohibits unreasonable searches and seizures. In addition, it sets requirements for issuing warrants: warrants must be issued by a judge or magistrate, justified by probable cause, supported by oath or affirmation, and must particularly describe the place to be searched and the persons or things to be seized.
A search warrant is a court order that a magistrate or judge issues to authorize law enforcement officers to conduct a search of a person, location, or vehicle for evidence of a crime and to confiscate any evidence they find. In most countries, a search warrant cannot be issued in aid of civil process.
In United States criminal law, probable cause is the standard by which police authorities have reason to obtain a warrant for the arrest of a suspected criminal or the issuing of a search warrant. There is no universally accepted definition or formulation for probable cause. One traditional definition, which comes from the U.S. Supreme Court's 1964 decision Beck v. Ohio, is when "whether at [the moment of arrest] the facts and circumstances within [an officer's] knowledge and of which they had reasonably trustworthy information [are] sufficient to warrant a prudent [person] in believing that [a suspect] had committed or was committing an offense."
An arrest is the act of apprehending and taking a person into custody, usually because the person has been suspected of or observed committing a crime. After being taken into custody, the person can be questioned further and/or charged. An arrest is a procedure in a criminal justice system, sometimes it is also done after a court warrant for the arrest.
Search and seizure is a procedure used in many civil law and common law legal systems by which police or other authorities and their agents, who, suspecting that a crime has been committed, commence a search of a person's property and confiscate any relevant evidence found in connection to the crime.
Terry v. Ohio, 392 U.S. 1 (1968), was a landmark U.S. Supreme Court decision in which the Court ruled that it is constitutional for American police to "stop and frisk" a person they reasonably suspect to be armed and involved in a crime. Specifically, the decision held that a police officer does not violate the Fourth Amendment to the U.S. Constitution's prohibition on unreasonable searches and seizures when questioning someone even though the officer lacks probable cause to arrest the person, so long as the police officer has a reasonable suspicion that the person has committed, is committing, or is about to commit a crime. The Court also ruled that the police officer may perform a quick surface search of the person's outer clothing for weapons if they have reasonable suspicion that the person stopped is "armed and presently dangerous." This reasonable suspicion must be based on "specific and articulable facts," and not merely upon an officer's hunch.
A Terry stop in the United States allows the police to briefly detain a person based on reasonable suspicion of involvement in criminal activity. Reasonable suspicion is a lower standard than probable cause which is needed for arrest. When police stop and search a pedestrian, this is commonly known as a stop and frisk. When police stop an automobile, this is known as a traffic stop. If the police stop a motor vehicle on minor infringements in order to investigate other suspected criminal activity, this is known as a pretextual stop. Additional rules apply to stops that occur on a bus.
A traffic stop, commonly referred to as being pulled over, is a temporary detention of a driver of a vehicle and its occupants by police to investigate a possible crime or minor violation of law.
United States v. Place, 462 U.S. 696 (1983), was a decision by the Supreme Court of the United States in which the Court held, 9–0, that the sniff of one's personal property in a public place by a specially trained police dog was not a "search" under the meaning of the Fourth Amendment. In the case, suspected drug trafficker Raymond Place had his luggage seized at LaGuardia Airport by agents with the Drug Enforcement Administration, which they exposed to a drug-sniffing dog and held onto for several days without a search warrant. Justice Sandra Day O'Connor wrote for the unanimous Court that the sniff of a dog is sui generis, or "uniquely pervasive", and thus police do not need probable cause for their dogs to sniff a person's belongings in a public place. The Court did rule, however, that detaining a person's belongings while waiting for a police dog to arrive did constitute a "seizure" under the Fourth Amendment.
Reasonable suspicion is a legal standard of proof in United States law that is less than probable cause, the legal standard for arrests and warrants, but more than an "inchoate and unparticularized suspicion or 'hunch'"; it must be based on "specific and articulable facts", "taken together with rational inferences from those facts", and the suspicion must be associated with the specific individual. If police additionally have reasonable suspicion that a person so detained is armed and dangerous, they may "frisk" the person for weapons, but not for contraband like drugs. However, if the police develop probable cause during a weapons frisk, they may then conduct a full search. Reasonable suspicion is evaluated using the "reasonable person" or "reasonable officer" standard, in which said person in the same circumstances could reasonably suspect a person has been, is, or is about to be engaged in criminal activity; it depends upon the totality of circumstances, and can result from a combination of particular facts, even if each is individually innocuous.
In the United States, the plain view doctrine is an exception to the Fourth Amendment's warrant requirement that allows an officer to seize evidence and contraband that are found in plain view during a lawful observation. The doctrine is also regularly used by Transportation Security Administration (TSA) officers while screening persons and property at U.S. airports.
The Police and Criminal Evidence Act 1984 (PACE) is an Act of Parliament which instituted a legislative framework for the powers of police officers in England and Wales to combat crime, and provided codes of practice for the exercise of those powers. Part VI of PACE required the Home Secretary to issue Codes of Practice governing police powers. The aim of PACE is to establish a balance between the powers of the police in England and Wales and the rights and freedoms of the public. Equivalent provision is made for Northern Ireland by the Police and Criminal Evidence Order 1989 (SI 1989/1341). The equivalent in Scots Law is the Criminal Procedure (Scotland) Act 1995.
"Stop and identify" statutes are laws in several U.S. states that authorize police to lawfully order people whom they reasonably suspect of a crime to state their name. If there is not reasonable suspicion that a crime has been committed, is being committed, or is about to be committed, an individual is not required to identify themselves, even in these states.
Frisking is a search of a person's outer clothing wherein a person runs their hands along the outer garments of another to detect any concealed weapons or objects.
Minnesota v. Dickerson, 508 U.S. 366 (1993), was a decision by the Supreme Court of the United States. The Court unanimously held that, when a police officer who is conducting a lawful patdown search for weapons feels something that plainly is contraband, the object may be seized even though it is not a weapon. By a 6-to-3 vote, however, the court held that the officer in this case had gone beyond the limits of a lawful patdown search before he could determine that the object was contraband, making the search and the subsequent seizure unlawful under the Fourth Amendment.
The powers of the police in Scotland, as with much of Scots law, are based on mixed elements of statute law and common law.
The powers of the police in England and Wales are defined largely by statute law, with the main sources of power being the Police and Criminal Evidence Act 1984 and the Police Act 1996. This article covers the powers of police officers of territorial police forces only, but a police officer in one of the UK's special police forces can utilise extended jurisdiction powers outside of their normal jurisdiction in certain defined situations as set out in statute. In law, police powers are given to constables. All police officers in England and Wales are "constables" in law whatever their rank. Certain police powers are also available to a limited extent to police community support officers and other non warranted positions such as police civilian investigators or designated detention officers employed by some police forces even though they are not constables.
Immigration and Naturalization Service v. Delgado, 466 U.S. 210 (1984), was a United States Supreme Court decision on the limits of worksite enforcement by immigration agents. Specifically, the Court ruled that factory raids by the Immigration and Naturalization Service (INS) were not illegal seizures under the Fourth Amendment to the U.S. Constitution.
Bailey v. United States, 568 U.S. 186 (2013), was a United States Supreme Court case concerning search and seizure. A 6–3 decision reversed the weapons conviction of a Long Island man who had been detained when police followed his vehicle after he left his apartment just before it was to be searched. Justice Anthony Kennedy wrote the majority opinion, and Antonin Scalia filed a concurrence. Stephen Breyer dissented.
United States v. Drayton, 536 U.S. 194 (2002), was a case in which the United States Supreme Court clarified the applicability of Fourth Amendment protections to searches and seizures that occur on buses, as well as the function of consent during searches by law enforcement. During a scheduled stop in Tallahassee, Florida, police officers boarded a Greyhound bus as part of a drug interdiction effort and interviewed passengers. After talking to two of the passengers and asking if they could "check [their] person", officers discovered the two passengers had taped several packages of cocaine to their legs. At trial, the passengers argued that officers violated their Fourth Amendment rights against unreasonable searches and seizures because the police engaged in coercive behavior and never informed them that their participation in the drug interdiction efforts was voluntary.
