Chaos: Charles Manson, the CIA, and the Secret History of the Sixties

by Tom O'Neill

A longtime lieutenant with the LAPD, Herrmann had an unusual background for law enforcement. He had a doctorate in psychology; he specialized in quelling insurgencies; he’d developed one of the first computer systems to track criminals and predict violent outbreaks in cities. Daryl Gates, the head of the LAPD from 1978 to 1992, hailed him as a “genius,” praising his technical aptitude in particular. But Herrmann’s work wasn’t limited to Los Angeles, or even to the United States. My FOIA request to the FBI yielded a collection of redacted documents detailing his extensive employment history. Concurrent with his time in the LAPD, he’d worked under contract for a dizzying list of American intelligence and military agencies: the air force, the Secret Service, the Treasury Department, the President’s Office of Science and Technology, the Institute for Defense Analysis, the Defense Industrial Security Clearance Office, and the Defense Department’s Advanced Research Projects Agency. Most of his work for these groups remains classified.
