Federal Surveillance of African Americans, 1920-1984
Between the early 1920s and early 1980s, the Justice Department and its Federal Bureau of Investigation engaged in widespread investigation of those deemed politically suspect. Prominent among the targets of this sometimes coordinated, sometimes independent surveillance were aliens, members of various protest groups, Socialists, Communists, pacifists, militant labor unionists, ethnic or racial nationalists, and outspoken opponents of the policies of the incumbent presidents.
