The narrow requirements of Nevada's stop-and-identify law meant that it did not run afoul of the Fourth Amendment. "In the ordinary course a police officer is free to ask a person for identification without implicating the Fourth Amendment." Since "Terry", it has been clear that a police officer who reasonably suspects that a person is involved in criminal activity may detain a person long enough to dispel that suspicion. Questions related to a person's identity are a "routine and accepted part of many "Terry" stops." Knowing a person's identity may, of course, help to clear a suspect and divert the attention of the police to another suspect. On the other hand, knowing the suspect's name may just as quickly confirm to the officer that the person is wanted for another, unrelated crime. In cases such as this, where the police are investigating a domestic dispute, officers "need to know whom they are dealing with in order to assess the situation, the threat to their own safety, and possible danger to the potential victim." "The request for identity has an immediate relation to the purpose, rationale, and practical demands of a "Terry" stop. The threat of criminal sanction helps ensure that the request for identity does not become a legal nullity." Balancing the intrusion into the individual's privacy against the extent to which the stop-and-identify law promotes legitimate government interests, the Court concluded that the Fourth Amendment did not prohibit Nevada from making it a crime for a person detained under conditions of "Terry" to refuse to disclose his name to a police officer upon request.
