Following the attacks of 9/11, the NYPD Intelligence Division developed a surveillance program that mapped, monitored, and profiled Muslim communities in New York City and nearby states. In August 2011, the extent of the covert program was disclosed in a series of Pulitzer-Prize winning investigative reports by the Associated Press (AP). The reports revealed that the NYPD was spying on mosques as well as Muslim student groups, businesses, and community organizations, undercutting claims that “its officers only follow leads when investigating terrorism.” This factsheet summarizes the implementation of this program and its effects on the community.
