Our rating: On the record. Confirmed by released government records or official investigations. Not a theory any more, though the theories around it may go further than the files do. How we rate.

01 What the theory says
The theory: the FBI didn't just watch political movements, it secretly worked to destroy them. That meant spreading lies, setting groups against each other, getting people fired, and trying to break the spirits of leaders such as Martin Luther King Jr.
02 Why people believe it
Because it's documented in the FBI's own files, released after burglars stole them in 1971 and confirmed by a Senate investigation. It's also why many people still assume intelligence agencies are working behind the scenes on today's movements.
03 What's on the record
Each point links to a primary source or official report.
- On March 8, 1971, a group calling itself the Citizens' Commission to Investigate the FBI broke into the FBI's field office in Media, Pennsylvania, took files and sent them to news organizations, exposing the program. (FBI Vault: COINTELPRO)
- The Senate's Church Committee found that from 1956 to 1971 the FBI ran covert programs aimed at groups including the Communist Party, Socialist Workers Party, "White Hate" groups, "Black Nationalist" groups and the New Left. Tactics included anonymous letters, planted press stories and attempts to provoke conflict within and between groups. (Church Committee, Book III (PDF))
- The Church Committee documented an FBI campaign against Martin Luther King Jr., including wiretaps and bugging, and an anonymous letter mailed to him in 1964 with recordings, which King read as urging him to kill himself. (Church Committee, Book III)
- FBI records on the program are posted in the Bureau's own FOIA library. (FBI Vault)
04 What's unproven or disputed
- That COINTELPRO-style operations never stopped. The FBI said the programs ended in 1971. Claims that the same tactics continued under other names come up often; specific cases have to be judged on their own evidence.
- FBI responsibility for specific deaths. Some cases, such as the 1969 police raid in which Black Panther leader Fred Hampton was killed, involved FBI informants and remain bitterly disputed. Claims that the FBI orchestrated particular killings go beyond what the Church Committee concluded.
05 Open questions
- How many COINTELPRO files were never released or were destroyed?
- Who were all the informants, and what did they do?
- What safeguards actually changed after the Church Committee, and do they work?
