40th Anniversary of Kent State Shootings

Today marks the 40th anniversary of the Kent State Shootings. On May 4th, 1970, National Guardsmen opened fire on hundreds of unarmed students at an antiwar rally at Kent State University in Ohio. The guardsmen fired off at least 67 shots in roughly 13 seconds. Four students were killed and nine others wounded. We hear from some of the survivors and we speak with Laurel Krause, the sister of Allison Krause, one of the four students killed, who is directing the Kent State Truth Tribunal.
