New York Magazine has an epic report on the secret unit built by the NYPD to infiltrate and monitor the city’s various communities for un-American sentiment:
The activities Kelly set in motion after 9/11 pushed deeply into the private lives of New Yorkers, surveilling Muslims in their mosques, their sporting fields, their businesses, their social clubs, even their homes in a way not seen in America since the FBI and CIA monitored antiwar activists during the Nixon administration.
Putting a CIA officer inside a police department was unprecedented. The CIA, by its very charter, was prohibited from having any “police, subpoena, or law enforcement powers or internal security functions.” But 9/11 had changed the equation.
To the extent Sanchez had an official title, it was the CIA director’s counterterrorism liaison to the state of New York. In reality, he was Cohen’s personal CIA representative, with an office at the CIA station in Manhattan and another at NYPD.
