It most certainly does. The Mexican Mafia (La Eme) is a prison gang that controls the southern California street gangs under the "Sureno" or "Southern" umbrella.
They are still very much a thing and separate but affiliated with Mara Salvatrucha (MS-13), which is mostly comprised of foriegners from central and south America. The 13 (M) is a giveaway as to their affiliation with La Eme.
p.s. The Mexican gangs in northern California are called Nortenos and the prison gang that controls them is "Nuestra Familia" or NF. N for Northern. (derogatory: "farmeros" or "farmers" and/or "busters." Call them that and see what happens. Call the surenos "scraps or scrapas" and see what happens.
In Fresno, which is in the middle, we have independent gang bangers called "Bulldogs." They are neither north or south.

And then there are the Sons of Anarchy.
Thanks for your boots on the ground info.
Thanks for the info on gangs. It should make it easier to take them out when their turn comes. Centrally controlled organizations are always easier to take out.
