Last week was the 40th anniversary of the Kent State shooting. But there was another campus shooting in May 1970 that has been largely forgotten by history: the shootings at Jackson State University in Mississippi. James "Lap" Baker was a student at the historically black university. He had endured brutal racism all his life, but he never expected that white police would open fire on unarmed black students. Lap tells Dick Gordon about what happened that warm May night, and how those thirty seconds of gunfire changed his life.
