<P> "Stop and identify" statutes are statutory laws in the United States that authorize police to legally obtain the identification of someone whom they reasonably suspect of having committed a crime . If there is no reasonable suspicion that a crime has been committed, is being committed, or is about to be committed, an individual is not required to provide identification, even in "Stop and ID" states . In the case of Utah v. Strieff (2016), the U.S. Supreme Court ruled that an officer's stop of Edward Strieff and his demand for identification from Strieff was unlawful under Utah state law, but that the evidence collected pursuant to the stop was admissible due to the determination that Strieff was subject to a pre-existing arrest warrant . Therefore, the pre-existing warrant "attenuated" the unlawful stop - and - identify . </P> <P> The Fourth Amendment to the United States Constitution prohibits unreasonable searches and seizures and requires any warrant to be judicially sanctioned and supported by probable cause . Terry v. Ohio, 392 U.S. 1 (1968) established that it is constitutionally permissible for police to temporarily detain a person based on an articulable reasonable suspicion that a crime has been committed, and to conduct a search for weapons based on a reasonable belief that the person is armed . The question whether it is constitutionally permissible for the police to demand that a detainee provide his or her name was considered by the U.S. Supreme Court in Hiibel v. Sixth Judicial District Court of Nevada, 542 U.S. 177 (2004), which held that the name disclosure did not violate the Fourth Amendment prohibition on unreasonable searches and seizures . The Hiibel case also held that, because Hiibel had no reasonable belief that his name would be used to incriminate him, the name disclosure did not violate the Fifth Amendment right against self - incrimination; however, the Court left open the possibility that Fifth Amendment right might apply in situations where there was a reasonable belief that giving a name could be incriminating . The Court accepted the Nevada supreme court interpretation of the Nevada statute that a detained person could satisfy the Nevada law by simply stating his name . The Court did not rule on whether particular identification cards could be required, though it did mention one state law requiring "credible and reliable" identification had been struck down for vagueness . </P>
