I assume there was a continuum of "investigative" activity by J.E.Hoover between Garvey and the death of M.L.King (and beyond?). What were some of the high(low) points? Where can I learn more?
Answered by Robin Kelley:
Yes there was a continuum. Theodore Kornweibel, who is interviewed in the film, wrote a very fine book about FBI surveillance and harassment of black activists called Seeing Red, which covers the early 1920s. Kenneth O'Reilly published a general book called Racial Matters: The FBI's Secret File on Black America, 1960-1972. There is not a lot written about the period in between, however, except in the context of histories of radical movements. Also, it is important to pay attention to local police activities in addition to the FBI. A fine book on this subject is Frank Donner, Protectors of Privilege: Red Squads and Police Repression in Urban America.
