Hour 1: In the 1950s and ’60s, Mississippi developed a secret spy agency charged with preserving segregation. We’ll talk this hour about the impact of the Mississippi State Sovereignty Commission with Rick Bowers, author of Spies of Mississippi: The True Story of the Spy Network that Tried to Destroy the Civil Rights Movement (National Geographic). Bowers’ book is the source material for an Independent Lens film airing Feb. 11 on KERA.
