Read that weeks ago.
The part of him not wanting to roll with the Blacks against Whites, and Southsiders... and paying the consequences for it doesn't surprise me. In California at least, if you don't stick with your "own" things could get really ugly for you. The thing I don't understand if he was in PC, why did they bunk him with a known gang member? It's almost like the prison officials were ordered by whoever the Black rep there is to give him a "buddy."
He seemed like he changed a lot from his young L.A. days. Sad story.
