Cointelpro Burglars Used Brilliant Trick In Previous Robbery


In 1971, a group of burglars broke in to an FBI office in Pennsylvania, stole reams of documents, and uncovered a vast intelligence program known as Cointelpro. The covert spying operation had for years targeted politicians, anti-war advocates, and civil rights leaders like Martin Luther King Jr., among others -- all under the watchful eye of FBI Director J.
