Crips bloods origins from children of black southern migrating farmer smaller gangs that formed to protect themselves against attacks from racist whites.
Black Panthers were a major influence in the community for a few years and of course cointelpro took them down. However crips and bloods took their place and allowed to morph into entities that destroyed their communities.
Superfly and other blackploitation movies having negative influence on the kids of that period.
14 year olds being allowed to buy guns from the gunshop
Gang members having morals.
Armory trucks dropping off military grade weapons in black LA neighborhoods.
Everything going on now is by design not no accident.
