On the other hand I really believe that prison gangs are becoming a major force in organized crime. They have extended their reach to their communities. La Eme has influence in the Mexican and Central American communities throughout California. Black Guerilla Family has spread its tentacles from the California prisons to the African-American communities in San Francisco, Oakland,...even as far as Baltimore. While I don't think the California Aryan Brotherhood is nearly as powerful as they once were, the Aryan Brotherhood of Texas on the other hand has influence not only in Texan communities, but also in Mississippi, Alabama, Oklahoma, Indiana,...and other Southern communities.
What the Cosa Nostra does for the Northeast and parts of the Midwest, prison-and street gangs are doing for the (South)west and the deep South.
It will only be a matter of time before the Southeast Asians will form a prison gang...
