The Associated Press published a report today detailing, for the first time, a unit within the CIA, referring to itself as the vengeful librarians, that is responsible for monitoring the vast and various social networks, local and international news, radio, and television, Internet chat rooms, and pretty much anything from which they can procure intelligence. The report is the first public admission by the CIA that yes spooks are eyeballing your Tweets and Facebook Wall posts for valuable information.
