Wow. Just how many of these Intelligence agencies were associated with the FBI? Here’s another one and it was gathering information on ‘domestic subversives’
https://en.wikipedia.org/wiki/COINTELPRO
COINTELPRO (acronym for COunter INTELligence PROgram) (1956-1971) was a series of covert, and at times illegal,[1][2] projects conducted by the United States Federal Bureau of Investigation (FBI) aimed at surveilling, infiltrating, discrediting, and disrupting domestic political organizations.[3][4] FBI records show that COINTELPRO resources targeted groups and individuals that the FBI deemed subversive,[5] including the Communist Party USA,[6] anti-Vietnam War organizers, activists of the civil rights movement or Black Power movement (e.g., Martin Luther King Jr. and the Black Panther Party), feminist organizations,[7] independence movements (such as Puerto Rican independence groups like the Young Lords), , and a variety of organizations that were part of the broader New Left. The program also targeted white supremacist groups including the Ku Klux Klan. Nationalist groups including Irish Republicans and Cuban exiles were also targeted.[8]
