That's because location, Mackinblack007.
La Eme started from mexican gangs in L.A then spread its membership and network throughout SoCal. BGF started in the Bay Area , Crips/Bloods/Hoovers in the L.A metro. There's a difference in criminal culture of NorCal & SoCal. Most from my understanding is that major cities (not all of course) don't care for crips/bloods and instead you have local crews/gangs.
I have no clue on this but you may; what would be the best example of blacks organizing in the criminal world---in the last 50 years or so? I mean what scale and scope? What would be the crowning achievement in terms of taking on Whitey...or whatever. Not talking shit I'm serious.
I don't follow black gang culture.
