ID

When do I have to show police my ID?

This is a tricky issue. As a general principle, citizens who are minding their own business are not obligated to "show their papers" to police. In fact, there is no law requiring citizens to carry identification of any kind.

Nonetheless, carrying an ID is generally required if you’re driving a vehicle or a passenger on a commercial airline. These requirements have been upheld on the premise that individuals who prefer not to carry ID can choose not to drive or fly.

From here, ID laws only get more complicated. In Hiibel v. Sixth Judicial District Court of Nevada, the Supreme Court upheld state laws requiring citizens to disclose their identity to police when officers have reasonable suspicion to believe criminal activity may be taking place. Commonly known as "stop-and-identify" statutes, these laws permit police to arrest criminal suspects who refuse to identify themselves.
