There's a book/documentary/soundtrack coming out about SF hunters point gangs 'big block' and 'westmob'. The audio book is narrated by joe blows sister who was involved with one of the gangs and the story is San Fransisco history that's never been told. They say they're telling the story not to glorify but to horify I think there was 20 killings in one month from the 2 gangs. The book/soundtrack is called 'let the record reflect'.
