"The present case begins where our prior cases left off. Here there is no question that the initial stop was based on reasonable suspicion, satisfying the Fourth Amendment requirements noted in "Brown". Further, the petitioner has not alleged that the statute is unconstitutionally vague, as in "Kolender". Here the Nevada statute is narrower and precise." The Nevada Supreme Court had held that the Nevada statute required only that the suspect divulge his name; presumably, he could do so without handing over any documents whatsoever. As long as the suspect tells the officer his name, he has satisfied the dictates of the Nevada stop-and-identify law.
