At Kent State University in Ohio, student protesters torched the ROTC building on campus and Ohio Governor James Rhodes responded by calling on the National Guard to restore order. Under harassment from the demonstrators, the Guardsmen fired into the crowd, killing four and wounding 11. The Guardsmen were later brought to trial for the shootings, but found not guilty.
President Nixon issued a statement deploring the Kent State deaths, but said that the incident should serve as a reminder that, "When dissent turns to violence it invites tragedy." The shooting sparked hundreds of protests and college shutdowns, as well as a march on Washington, D.C., by 100,000 people. The National Student Association and former Vietnam Moratorium Committee leaders called for a national university strike of indefinite duration, beginning immediately, to protest the war. At least 100 colleges and universities pledged to strike. The presidents of 37 universities signed a letter urging President Nixon to show more clearly his determination to end the war.
