What did the declassified documents reveal?

COINTELPRO – New Left Chicago Division, a memorandum from the Federal Bureau of Investigation dated thirty December, nineteen seventy, and related field reports, released through The Black Vault’s online archive. The document offers a rare glimpse into the bureau’s internal assessment of the Worker Student Alliance, the Progressive Labor Party, and the Weatherman organization during a period of intense campus activism. The file was made public under a Freedom of Information Act request filed by a private researcher, released on the archive’s website in early twenty twenty‑two. The declassification authority is listed as the bureau’s Office of the General Counsel, and the material is reproduced as the best copies available from the original files.

Should they attempt to secure space, recommendations will be made, such as advising reliable sources at Illinois Bell Telephone Company of the poor credit rating of this group, anonymous mailings to property owners in the area, etc., in an effort to disrupt their efforts to establish a headquarters in Chicago.” A second memorandum, dated twenty two January, nineteen seventy‑one, reports on a fugitive investigation targeting members of the Weatherman group. It notes that numerous contacts have been made among all elements in the Chicago area, emphasizing the dangerousness of the extremists and indicating that the pressure of the investigation has made it difficult for them to organize major disruptive actions.
