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.
No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offence to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.
In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the State and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the Assistance of Counsel for his defense.
That the Fourth Amendment was intended to protect against arbitrary arrests as well as against unreasonable searches was early assumed by Chief Justice Marshall and is now established law. At the common law, it was proper to arrest one who had committed a breach of the peace or a felony without a warrant, and this history is reflected in the fact that the Fourth Amendment is satisfied if the arrest is made in a public place on probable cause, regardless of whether a warrant has been obtained. However, in order to effectuate an arrest in the home, absent consent or exigent circumstances, police officers must have a warrant. The Fourth Amendment applies to ‘‘seizures’‘ and it is not necessary that a detention be a formal arrest in order to bring to bear the requirements of warrants or probable cause in instances in which warrants may be forgone. Some objective justification must be shown to validate all seizures of the person, including seizures that involve only a brief detention short of arrest, although the nature of the detention will determine whether probable cause or some reasonable and articulable suspicion is necessary.
Until relatively recently, the legality of arrests was seldom litigated in the Supreme Court because of the rule that a person detained pursuant to an arbitrary seizure—unlike evidence obtained as a result of an unlawful search—remains subject to custody and presentation to court. But the application of self-incrimination and other exclusionary rules to the States and the heightening of their scope in state and federal cases alike brought forth the rule that verbal evidence, confessions, and other admissions, like all derivative evidence obtained as a result of unlawful seizures, could be excluded. Thus, a confession made by one illegally in custody must be suppressed, unless the causal connection between the illegal arrest and the confession had become so attenuated that the latter should not be deemed ‘‘tainted’‘ by the former. Similarly, fingerprints and other physical evidence obtained as a result of an unlawful arrest must be suppressed.
- The provisions of the 4th Amendment to the United States Constitution are applicable to any detention of a person for investigation of suspected criminal conduct irrespective of whether or not the detention amounts to an arrest or not; however, such a temporary detention is not a violation of the 4th Amendment if the officers acted upon specific and articulable facts which would “warrant a man of reasonable caution in the belief that the action taken was appropriate”; in other words, the officers may act on something less than “probable cause,” but they may not act simply on the basis of good faith based upon nothing more substantial than “inarticulate hunches.”
- A police officer who has temporarily detained a person for investigation of suspected criminal conduct without making a formal arrest is not required to warn the detained person of his constitutional rights under Miranda v. Arizona, 384 U.S. 486, 16 L.Ed. 2d 694, 86 S.Ct. 1602 (1966), until the initial suspicions which led the officer to make the “stop” are transformed into “probable cause” to believe the person confronted has committed an offense or until the suspect has a reasonable basis, in fact, to believe that he is under arrest (i.e., in custody of the police and not free to leave); at either of these points, the required warnings must be given in order to ensure the admissibility in evidence of any incriminating statements thereafter made by the suspect.
