>> the sound is good. >> we weren't rolling. damn it! >> we're good, we're good. never again. >> are you tired? >> this is helping. due to mature subject matter, viewer discretion is advised. msnbc takes you behind the walls of america's most notorious prisons to a world of chaos and danger. now, the scenes you've never seen. "lockup: raw." the day we arrived at colorado state penitentiary, a super max prison at the base of the rocky mountains, we found a sterile austere environment. steel doors behind which inmates are locked up 23 hours a day.

but despite his surroundings, inmate shawn shields was in high spirits. when he sat down with us, he was eager to help our producer get the interview under way. >> quiet on the set, you boneheads. >> it's a prison, you know. >> all right. let's roll tape. >> then he calmly told us how he got 16 years added to his original sentence of 12 for robbery. >> me and another inmate had an altercation, i manipulated the door so that it wouldn't latch completely. and when he came out to walk, i came down after him and proceeded to stab him. >> why? was it because you guys weren't getting along. >> it was just a verbal altercation. >> does that happen a lot in

here? >> um, there is a lot of verbal altercations between people. you've got to understand, there's 16 men living together behind closed doors with stress, animosity towards one another in some cases. and it's not always a pleasant place to be. >> when inmates erupt, no one is safe. including correctional staff. >> we had an inmate that was on his way to the rec yard and came behind an officer and used a derogatory statement toward him. i immediately told him that his recreation was being taken for that comment. he decided to lean forward as if he was going to brace himself and he just bit right into my left arm. this is my left arm the day that the bite occurred. he bit in so fast and so hard, that i didn't even feel him biting in. and he severed the nerve in my arm where i now have permanent damage. >> call right now. 209. >> while officer mills' bite wound was severe, his ordeal wasn't nearly as terrifying as the nightmare one of his fellow officers experienced.

in this previously unaired footage provided to "lockup" by the prison, hostage negotiators are outside the cell of inmate willie hill. moments earlier, hill overpowered a female correctional officer, shackled her with her own restraints, and was now holding her at knifepoint in his cell. >> she's keeping him distracted. >> meanwhile, riverbend's emergency response team suits up for action. while the negotiator speaks with hill, the team quietly assembles undetected outside the cell door. >> here we go. coming in. >> at a precise moment, the door is opened and the team rushes the cell, setting off a flash-bang grenade. [ screaming ] >> stop!

>> the team uses pepper spray to subdue the inmate. [ yelling ] >> within seconds, the still-shackled officer is pulled to safety. >> get the door. >> a short time later, hill is also removed from his cell. though dazed by the effects of the pepper spray, hill is uninjured.

he had assaulted two officers. >> coming up on "locked up raw." >> he raises the stakes.

>> i'm asking one more time and that's it. t only pay three quarters of what it takes to replace it. what are you supposed to do? drive three quarters of a car? now if you had liberty mutual new car replacement, you'd get your whole car back. i guess they don't want you driving around on three wheels. smart. with liberty mutual new car replacement, we'll replace the full value of your car. see car insurance in a whole new light. liberty mutual insurance. ...one of many pieces in my i havlife.hma... so when my asthma symptoms kept coming back on my long-term control medicine. i talked to my doctor and found a missing piece in my asthma treatment with breo. once-daily breo prevents asthma symptoms. breo is for adults with asthma not well controlled on a long-term asthma control medicine, like an inhaled corticosteroid. breo won't replace a rescue inhaler for sudden breathing problems. breo opens up airways to help improve breathing for a full 24 hours. breo contains a type of medicine that increases the risk of death from asthma problems and may increase the risk of hospitalization in children and adolescents.
