(b) The officer’s conduct did not violate Hiibel’s Fourth Amendment rights. Ordinarily, an investigating officer is free to ask a person for identification without implicating the Amendment. INS v. Delgado, 466 U.S. 210, 216. Beginning with Terry v. Ohio, 392 U.S. 1, the Court has recognized that an officer’s reasonable suspicion that a person may be involved in criminal activity permits the officer to stop the person for a brief time and take additional steps to investigate further. Although it is well established that an officer may ask a suspect to identify himself during a Terry stop, see, e.g., United States v. Hensley, 469 U.S. 221, 229, it has been an open question whether the suspect can be arrested and prosecuted for refusal to answer, see Brown, supra, at 53, n. 3. The Court is now of the view that Terry principles permit a State to require a suspect to disclose his name in the course of a Terry stop. Terry, supra, at 34. The Nevada statute is consistent with Fourth Amendment prohibitions against unreasonable searches and seizures because it properly balances the intrusion on the individual’s interests against the promotion of legitimate government interests. See Delaware v. Prouse, 440 U.S. 648, 654. An identity request has an immediate relation to the Terry stop’s purpose, rationale, and practical demands, and the threat of criminal sanction helps ensure that the request does not become a legal nullity. On the other hand, the statute does not alter the nature of the stop itself, changing neither its duration nor its location. Hiibel argues unpersuasively that the statute circumvents the probable-cause requirement by allowing an officer to arrest a person for being suspicious, thereby creating an impermissible risk of arbitrary police conduct. These familiar concerns underlay Kolender, Brown, and Papachristou. They are met by the requirement that a Terry stop be justified at its inception and be “reasonably related in scope to the circumstances which justified” the initial stop. Terry, 392 U.S., at 20. Under those principles, an officer may not arrest a suspect for failure to identify himself if the identification request is not reasonably related to the circumstances justifying the stop. Cf. Hayes v. Florida, 470 U.S. 811, 817. The request in this case was a commonsense inquiry, not an effort to obtain an arrest for failure to identify after a Terry stop yielded insufficient evidence. The stop, the request, and the State’s requirement of a response did not contravene the Fourth Amendment. Pp. 6—10.
