this was the aryan brotherhood. i covered this up two years ago. came into prison august 17th of 2006. i covered this up september of the same year. three weeks after me being in prison. i had a case with another aryan, which they say i told on them. so i get down here and the same guys i supposedly told on are here in this prison. >> at the prison we've had a lot of problems with an aryan organization. the big problem is instead of fighting between each other, the whites and the blacks, what's been happening more recently is problems with the aryans going after each other. and a lot of it is because there's been influx with the organization, and their leadership, and there's a struggle for control. >> since dropping out of the aryan brotherhood, nick compton says being attacked is only one problem. >> i'm being extorted for money. my mother and sister sent me over $500 since i've been here. >> can you identify? >> yeah, no problem. >> compton is due to be released from prison in three months, but risks putting himself in greater danger with the ar

we have a mexican mafia, we have nf, northern familia, the northern structure, the aryan brotherhood and nazi low rider. these guys are here because of their criminal activity. it's either drug related, assaults on staff assaults on other inmates. we do house the worst of the worst here, therefore, security is paramount. while you've been validated as a gang member, you're going to remain in shu. >> one of the most dangerous inmates in the shu is a gang member, whose goal from childhood was to become a made m man in the mexican mafia. he is shackled by two officers, they insisted our staff wear puncture resistant masks when interviewing him. heart's always been brown. i was in l.a. county jail for 3.5 years. they put me on trial for murder/robbery and possession of heroin. whether i was innocent or not, just by looking at me, i was guilty. and i was pissed. there was no way i was going to let the system give me life in prison unless it was on my terms and i earned it. so -- oh, i owned it all right. >> we listened to tapes of a jailhouse admission to a murder to become a made man in

member, and that began my life in a prison gang. >> the aryan brotherhood exploited his violent natureusing him to carry out their dirty work. >> prison gangs involved everything from stabbings, killings, drugs, weapons, whatever needed to be done, i did it. >> we warn you, the detailing of his violent acts is extremely graphic. >> there was an inmate that came up to the tier. efs accused of raping a woman out on the streets. because i was up and coming in the gang at that time, it fell to me to either make another inmate kill him or i myself kill him. i chose to kill him myself. if i didn't kill this guy or if i didn't have this guy killed, then i myself would be killed. that's how the prison gang system works. so me and two friends of mine, fellow gang members, went into his cell to play cards with him. the plan was for his partner in pinochle lose on purpose and to do push-ups. and when he got down to do push-ups, i got down on his back and applied a little pressure. that was my excuse to get up next to him. at which time, i put my arm around his throat, kind of choked him out a lit

. >> he transitioned from a drug user on the streets to an enforcer for the aryan brotherhood in prison, responsible for collecting drug debts. >> my policy was if one of pie people got in a drug debt i would pull them up and say you're done, cut up their credit card, get together with white, pay their debt and he's done. if he gets drugs again then we'll stab him because he violated and i agree with that. there is drugs in prison, obviously. you get on a phone and cry to mom, i need $100 i broke a tv, whatever lie you want to tell. you get it to the street to the connection their old lady brings the dope and bring it back in. somebody will come to visit and they'll have their little balloons and they stick them up their ass, when they come back they [ bleep ] them out and clean them up, paper it up and cell it. >> coming up, tim's drinking is about to get worse. >> a slight hint of alcohol smell, so -- >> and, they've hit inmates at the job site. now the isu team is targeting their home. >> get to the door. pop them. >>> plus -- >> urine analysis. >> last-minute drug test could end the
