<P> Police may question a person detained in a Terry stop, but in general, the detainee is not required to answer . However, many states have "stop and identify" laws that explicitly require a person detained under the conditions of Terry to identify himself to police, and in some cases, provide additional information . </P> <P> Before Hiibel, it was unresolved whether a detainee could be arrested and prosecuted for refusing to disclose his name . Authority on this issue was split among the federal circuit courts of appeal, and the U.S. Supreme Court twice expressly refused to address the question . In Hiibel, the Court held, in a 5--4 decision, that a Nevada "stop and identify" law did not violate the United States Constitution . The Court opinion implied that a detainee was not required to produce written identification, but could satisfy the requirement merely by stating his name . Some "stop and identify" laws do not require that a detainee identify himself, but allow refusal to do so to be considered along with other factors in determining whether there is probable cause to arrest . In some states, providing a false name is an offense . </P> <P> As of February 2011, the Supreme Court has not addressed the validity of requirements that a detainee provide information other than his name, however some states such as Arizona have specifically codified that a detained person is not required to provide any information aside from their full name . </P> <P> A detention requires only that police have reasonable suspicion that a person is involved in criminal activity . However, to make an arrest, an officer must have probable cause to believe that the person has committed a crime . Some states require police to inform the person of the intent to make the arrest and the cause for the arrest . But it is not always obvious when a detention becomes an arrest . After making an arrest, police may search a person, his or her belongings, and his or her immediate surroundings . </P>
