The insanity ruling that sent President Ronald Reagan's would-be assassin, John Hinckley Jr., to a government psychiatric hospital rather than prison was handed down 34 years ago, but its repercussions still affect hundreds, if not thousands, of people who commit a crime and also have mental illness. These consequences and the insanity defense itself were forced into the national spotlight again on Wednesday, when a federal judge said Hinckley would be released to live with his elderly mother in Williamsburg, Va.

For some people, the attack on police officers by a gunman in Dallas this summer brought to mind another attack by a sniper in Austin 50 years ago – on Aug. 1, 1966. That's when student Charles Whitman stuck his rifle over the edge of the clock tower at the University of Texas at Austin and started shooting. Ultimately, he killed 16 people — and wounded more than 30 others. For decades, people have struggled to figure out why. There have been theories about abuse, a brain tumor and, of course, mental illness. (Silverman, 7/29)
