In early 1942, FBI Director J. Edgar Hoover wrote to Joseph Roos that the Bureau is "exerting every possible effort under the existing national defense statutes to protect the internal security of our nation against all subversive elements..." Hoover is explaining to Roos why stricter action cannot be taken against extemist groups and individuals, mentioning Robert Noble by name. (Noble was a known fascist who would, two years later, be among the defendants in the Sedition Trial.) Hoover states: "We are... a fact finding agency and we could not play the role of a censor." He invites Roos to provide any information he may acquire about subversive activities to the Special Agent in Los Angeles. 9.25 x 7 in.
