Here's an excellent, recent vid on COINTELPRO. It covers it's inception with the civil rights movement, up through Hal Turner being exposed as being on the FBI payroll. Also, provocateurs at protests and within the 9/11 truth movement and former MI5 agent David Shayler, mind controlled, transvestite, doomsday, religionist.
Cointelpro, Provacateurs,Disinfo Agents.
