The Federal Bureau of Investigation used counterterrorism agents to investigate the Occupy Wall Street movement, including its communications and planning, according to newly disclosed agency records. The F.B.I. records show that as early as September 2011, an agent from a counterterrorism task force in New York notified officials of two landmarks in Lower Manhattan - Federal Hall and the Museum of American Finance - that their building was identified as a point of interest for the Occupy Wall Street." In the following months, F.B.I. personnel around the country were routinely involved in exchanging information about the movement with businesses, local law-enforcement agencies and universities. An October 2011 memo from the bureau's Jacksonville, Fla., field office was titled Domain Program Management Domestic Terrorist. The memo said agents discussed "past and upcoming meetings" of the movement, and its spread. It said agents should contact Occupy Wall Street activists to ascertain whether people who attended their events had "violent tendencies." Since the Sept. 11, 2001, attacks, the F.B.I. has come under criticism for deploying counterterrorism agents to conduct surveillance and gather intelligence on organizations active in environmental, animal-cruelty and poverty issues. The records were obtained by the Partnership for Civil Justice Fund, a civil-rights organization in Washington, through a Freedom of Information request to the F.B.I.
