One of America's more famous documentarians, Errol Morris, was intrigued by Tom O'Neill's Chaos, a 2019 book delving into the mysteries around the murders committed in 1969 by people associated with the hippie cult leader Charles Manson.
In a new Netflix feature documentary exploring O'Neill's theories and findings, Morris shows his work, and we hear him telling O'Neill on camera he isn't quite buying the story O'Neill is selling.
Partly because of his connections to the Haight Ashbury Free Medical Clinic, which was haunted by CIA-associated mind control researcher Louis Jolyon West, and partly because of the mysterious leniency in how the legal system treated Manson before he was eventually arrested for the murders, O'Neill thinks it likely Manson was either a confidential informant and thus under the law's protection to some extent, or carrying out a CIA-planned experiment using something like West's techniques to turn his "Family" into mind-controlled murderers.
