A new documentary film, MLK/FBI, is about how the FBI sought someone close to King to watch and report on him. The film from director Sam Pollard shows how its two title subjects came to be enemies. Pollard shows how FBI chief J. Edgar Hoover used the full force of the law enforcement agency to attack the nonviolent movement for civil rights in the 1960s. Wiretaps, blackmail and informants were all used in the operations to find legal or moral wrongdoing by King. The spying was part of a wider government campaign to find and destroy suspected communist influences in the U.S. The activity against King represents the darkest part of the Bureau’s history, former FBI Director James Comey says in the film.
