Louis Jolyon West, Jolly, the psychiatrist who visited Ruby in prison just before Ruby went stark raving mad and could not testify at his trial, was also involved in the CIA's MK-Ultra program and ran a free clinic in San Francisco's Haight-Ashbury district where Charles Manson and his "family" were frequent visitors. All the details are in Tom O'Neill's book, Chaos: Charles Manson, the CIA, and the secret history of the sixties with sixty-three pages of footnotes. Although the book is thorough, it is not the most scintillating of books but is essential if you are writing a doctoral thesis.
