I was a teenager when the Manson murders went down, in the autumn of 1969 of course, the cruel and inexplicable murder of a movie star and several of her friends made all the headlines, and had lots of law-abiding citizens looking over their shoulders and being very careful about locking the doors and windows of their homes at night. It wasn’t until some time later that the associated murders of an elderly retired couple also hit the headlines of the LA Times, and other national newspapers. A blood-drenched, hippy cult with a weirdly charismatic leader had committed those murders in order so they claimed to trigger a devastating racial war, which they termed ‘helter-skelter’ from a Beatles song moderately popular at the time.
