Nation of Islam: Cult of the Black Muslims/Chapter 1
CONFIDENTIAL
I. ROLE OF FBI
One of the FBI's many responsibilities is that of investigating members of "basic revolutionary organizations or groups" who are dangerous or potentially dangerous to the internal security of the United States.
Persons included under this responsibility are leading functionaries and active, militant members of the Nation of Islam (NOI), who because of their fanatical antiwhite and anti-United States Government teachings and beliefs would be potentially dangerous and likely to seize upon the opportunity presented by a national emergency to endanger the public safety and welfare.
Therefore, the FBI must determine the identities, whereabouts, and activities of these individuals constituting a threat to the internal security, and must develop sufficient information and evidence to sustain appropriate action against such individuals or to control their movements and activities in the event of a national emergency.
