The Justice Department is refusing to reopen an investigation into the Kent State shootings just weeks ahead of its 42nd anniversary. On May 4th, 1970, National Guardsmen opened fire on hundreds of unarmed students at an antiwar rally at Ohio’s Kent State University. Four students were killed, and nine others wounded. Survivors of the massacre had called for a new federal probe two years ago following the discovery of an audiotape from the day of the shootings. The survivors say a National Guard officer can be heard issuing a command to fire followed by gunshots. But on Tuesday, the Justice Department rejected the request, saying the new audiotape is inconclusive. A group of Kent State survivors say they plan to respond by bringing the case to an international court.
