Texas Syndicate are some scary dudes. They run the Texas prisons, as well as the illicit drug trade on the streets of most cities throughout Texas. The last two top leaders of this gang both resided in Austin until they were brought up on RICO charges.
I'm not racist. I just like the name. Better than "Aryan Nation", better than "La Eme", etc. I'm a t shirt prison gang member.
I talked to a guy a while back who is a cop from a gang squad. He said that there is a prison gang called the Tango Blasters which looks like it is taking over the Texas prisons.
IIRC, the Tango Blast works more like a biker gang; not quite as organized as the other prison gangs. Membership is pretty much related to fighting and stuff. members keep there own profits from criminal activities rather than giving them to the gang.
