The Ohio National Guard opened fire on unarmed college students during a war protest at Kent State University on May 4, 1970. Four students were killed, and nine others were injured. Not all of those hurt or killed were involved in the demonstration, which opposed the U.S. bombing of neutral Cambodia during the Vietnam War. (AP Photo/Tony Dejak)
