The "white gang" that GmanJoe is referring to from Las Vegas are known as the "311 Boys". 311 is a reference for KKK (3, 11th letter of alphabet, really stupid).
They came from a snobby suburbanite area of Las Vegas, and were nothing more than rebellious rich white boys.
By the way, the woman in this video died from this beating. Don\'t bother asking for proof, I\'m not sifting through Offtopic.com archives.
