For 20 years, journalist Tom O'Neill immersed himself in an investigation of one of the most bizarre and gruesome crimes in America, the Manson Murders. Seven people, including director Roman Polanski's pregnant wife, were stabbed to death by followers of Charles Manson in California in 1969. O'Neill started looking into the murders on assignment for a magazine. He ended up spending two decades asking the question that's never been answered to anyone's satisfaction; why. He explains why he thinks much of what we accept as fact is fiction in his book, Chaos: Charles Manson, the CIA, and the Secret History of the Sixties.
