A resent U.S. Supreme Court ruling on a Nevada rancher held that a police officer can arrest someone if they will not produce a ID. Reason: For the safety of the officer. Forgot what year it was, somewhere around 2000-2004. The incident happen in the late 90's.
Edward C. Lawson is an African American civil rights activist, who was the pro se defendant in the case of Kolender v. Lawson (461 U.S. 352, 1983)
in which the United States Supreme Court ruled that a police officer could not arrest a citizen merely for refusing to present identification.
