The John Lennon FBI files

"FROM: DIRECTOR, CENTRAL INTELLIGENCE AGENCY"
CIA Director Richard Helms sent this coded teletype to Hoover on February 10, 1972 (CIA-4 page 1). The subject is "JohnLennon and Project 'Yes'." Here, the CIA reports that Lennon is involved in a project "which will include the use of video tapes, films, and special articles" - not exactly a crime in America - and participation by "a caravan of entertainers." It's hard to see why any law enforcement agency, much less the CIA hada legitimate reason for monitoring "a caravan of entertainers."
