1950: FBI Begins to Build Database to Track Suspect US Citizens

The FBI, led by director J. Edgar Hoover, begins to “accumulate the names, identities, and activities” of American citizens who are regarded as suspect. The information is gathered in a “security index,” which rapidly expands. In a letter to the White House during the Truman administration, Hoover will state that in the event of certain emergency situations, suspect individuals would be held in detention camps overseen by “the National Military Establishment.” By 1960, a congressional investigation will later reveal, the FBI list of suspicious persons will include “professors, teachers, and educators; labor-union organizers and leaders; writers, lecturers, newsmen, and others in the mass-media field; lawyers, doctors, and scientists; other potentially influential persons on a local or national level; [and] individuals who could potentially furnish financial or material aid” to unnamed “subversive elements.” [Radar, 5/2008]
