Given the deeply-intertwined relationship of the CIA and the New York Police Department, it just makes sense that the CIA would need to periodically remind its personnel that the NYPD isn't the sort of intelligence agency they can share US persons information with.
This comes from a CIA quiz obtained by the ACLU as part of an FOIA lawsuit. That the CIA would single out the NYPD on its test is significant. The NYPD likes to believe it's an intelligence agency on par with the FBI and CIA. Despite having zero reason to do so, the NYPD sends its officers all over the world to gather intelligence after terrorist attacks. No one has ever asked the NYPD to do this, but it continues to invite itself to various ground zeroes, where it is usually greeted with a mixture of befuddlement and anger.
The CIA, however, remains inextricably (and perhaps, willfully) entangled with the Little Intelligence Agency That Isn't. Two former CIA employees were instrumental in setting up its "Demographics Group," which engaged in pervasive surveillance of New York City Muslims. The privacy and civil liberties violations this group engaged in made the "intelligence" gleaned so toxic not even the FBI would touch it.
