Those were crazy days to be in LA.
For want of much else on TV right now I'm watching the series Aquarius, the fictional account of a detective in LA (David Duchovny) during the days when the Manson Family is on the rise...It's not great. The writers strain themselves to make sure we all get that blacks, Hispanics, women and Gays are all treated terribly, thus justifying all the whining and marching around since. So I'm not recommending it.
But there are some parts that aren't bad. The guy playing Manson does a decent job of almost making you feel he's a human broken by his terrible upbringing, just before he does something like viciously punching out his mother and turning her over to a biker gang as a toy.
