Lynette "Squeaky" Fromme is unrepentant and still worships Charles Manson. She escaped once and used her two days of freedom to try to visit Charlie in prison.
She's even got here own website.
Manson's crowd were early Animal Rights activists - crazy Charlie said he did it all for "ATWA" (air, trees, water, animals). He convinced Fromme that because she had red hair, she was to save the redwoods of California. Fortunately, the idiot had two empty chambers in the gun and the gun didn't go off.
The were all vegans and/or vegetarians back then too.
