Questions continue to linger about the role of a clandestine CIA operative within the New York City Police Department. The unnamed agent, who arrived in July, serves as assistant to the deputy commissioner of intelligence, but his specific responsibilities are not clear. The AP revealed the existence of the agent in August and detailed how the CIA helped the NYPD develop a so-called “Demographics Unit” that used informants, known as “mosque crawlers,” to monitor sermons without any evidence of wrongdoing and spy on people carrying out jobs typically done by Muslims. Senior U.S. officials have offered differing accounts on the operative’s place in the department. NYPD Commissioner Ray Kelly claims he provides officers with information “usually coming from perhaps overseas,” but “doesn’t have access to any of our investigative files.” David Petraeus, director of the CIA, meanwhile, says the agent is an adviser, despite the fact that the agency already has someone doing that job. The possibility that the agent is wearing two hats in his roles within the spy agency and the world’s largest police department has raised concerns among many.
