due to mature subject matter, viewer discretion is advised. msnbc takes you behind the walls of america's most notorious prisons into a world of chaos and danger. now, the scenes you've never seen. "lockup raw." >> it's a world where the threat of danger dictates every action and every decision. >> i have seen stabbings over drugs. i've seen stabbings over money owed for canteen. >> i was holding his head on the ground digging one of his eyeballs out. having technical difficulties with that. >> i have seen child molesters get stabbed.

>> i hit the inmate. i grabbed him by his arm. i slipped. i didn't realize when i slipped. it was all blood. >> a world that "lockup" producers and camera crews explore on a regular basis. >> when we walk into prison with our camera crews, inevitably we attract attention. but sometimes it's not the kind of attention you want to attract. [ bleep ], and we don't need you around anymore. >> shooting in prison is very controlled for the most part until all hell breaks loose. >> a world where even the most heinous violations are common place. >> shot urine into my eye and mouth area. >> advising staff he has prepared feces and urine for us. when our producers traveled to alaska, they quickly realized they were about to enter a

prison unlike any other. >> i would argue, spring creek correctional center is probably the most beautiful prison in the united states. we're located adjacent to resurrection bay. we have mountains. we have a river behind us. we have a glacier above us. the setting is just perfection. >> but inside the walls of spring creek, natural beauty gives way to the harsh reality of a maximum security penitentiary. >> we're at the end of the road for the state of alaska department of corrections the worst behaved prisoners end up here. >> those who pose the greatest threat to other inmates and staff are segregated in house one, the lockdown unit. >> basically, minimum rights. minimum, they're in their cells for 23 hours a day. >> on the day we wanted to interview him, house one inmate, antonio robertson was in an especially foul mood. >> [ bleep ], [ bleep ]. [ bleep ]. >> calm down.

>> every one of you [ bleep ], [ bleep ], i'm going to start with -- [ bleep ]. we need more. what do you want to know? >> robertson, serving a 60-year sentence for murder has spent most of the last two years in house one. >> why are you in here? >> in house one. it's a long story. i been being assaulted so i assault people back. i'm about my stuff. i refuse to let myself be assaulted and not fight back. >> robertson not only fights with other inmates. he fights with staff as well. >> i was disrespected. i decided to make the guys do a cell extraction. >> days before our interview, the prison's correctional emergency response team had to forcibly remove robertson from his cell for refusing to follow orders. these cell extractions are videotaped by the prison for legal reasons.

>> this use of force was authorized. >> extraction team officers always prepare for anything the inmate might have in store for them. >> advise house staff he has prepared feces and urine for us. >> because they disrespected me, all this cuff up, they want to talk all that mess and all of a sudden in front of all these prisoners and it made me a little -- they say do you want to cuff up? >> no i'm not going to cuff up. you disrespected me. we're going to do this. >> cuff up. >> with robertson still refusing orders, the extraction team disperses pepper spray into his cell. >> but it appears to have little effect. >> they used the cayenne pepper stuff. it does burn.

i've gotten used to it already. i knew it was going to hurt. i did it anyway. i'm doing a life sentence and there is no way i'm going to let an officer disrespect me in front of another prisoner. >> a second round of pepper spray floods the cell. robertson, however, stands firm. moments later, the team rushes the cell. the lead officer activates an electronic stun shield capable of delivering a 50,000-volt shock. temporarily incapacitated, robertson is finally removed from his cell and cuffed.

robertson is then taken to a holding area to rinse the pepper spray from his eyes and face. >> are you guys going to leave me here forever? you could at least be proud i fought back. >> nobody really got hurt. well, i didn't get hurt. because i -- i'm not trying to really get hurt until i'm ready to get hurt. but if i do get hurt, well -- that's just one of the consequences of doing battle. not far from robertson's cell is an inmate also known to treat prison like a war zone.

>> most of my interests are like firearms and stuff, so this is one of my doodles. >> that's a pretty detailed doodle. >> well, i have plenty of time on my hands. >> for inmate john bright, plenty of time means a 99-year sentence for murder. >> i got in trouble for being a -- a -- a hitman for organized crime. i thought that organized crime was cool. i thought drug dealers were cool. i watched "scarface" 20 times, bought the video when it cost $100. 1984 when it came out. i watched it 100 times over and over again. >> he claims to be wrongfully convicted but doesn't deny his taste for violence. >> i never killed anyone. i'm a fighter. i'm not a hitman. i'm not a murderer. i'm not a back stabber. i am a fighter. i have been in a fight. i've been in a fight on charlie mod. i've been in a fight on the yard. >> at this point in time he is one of our extreme management

problems. he doesn't play well with others. and so he stays here. >> i don't go, hey, i'm looking for somebody to get in a fight with. this guy looks like a good candidate. i will be watching tv one day trying to be nonaggressive, nonconfrontational, here comes mr. idiot inmate. crack-smoking child molester and changes the tv channel. well if i get in an argument with the guy he is going to want to fight. we get in a fight he is going to providence hospital. i'm going to house one. >> and bright has sent fellow inmates to the hospital. >> he got in a fight with a prisoner. he bit his finger off. >> i got ahold of one of his fingers, when i seen i could crush through the bone. i got a better grip. and bit a third of his right index finger off. he started screaming. he got up. it was bleeding all over and i spit his finger on the floor. >> he bit off his finger. he didn't succeed in what he was

trying to do. >> holding him on the ground. digging one of his eyeballs out. i've had technical difficulties with that. i've been trying that the last couple times. >> what? >> popping their eye out. i beat on them and broke them. so i decided to try blinding one seeing if that makes them understand to leave me alone. >> during our interview, bright indicated he still maintains hope in prison and if he ever loses it, there could be real trouble. >> if i woke up tomorrow and decided i'm going to live here and never go home, never have a life, i would be killing people. if i decided this is what i got coming and there is nothing to live for and they're not going to let me out of the hole they would have to weld my door shut forever. >> though he is an intimidating presence, bright maintains he is really nothing to worry about. >> the littlest guy here is not scared of me. i don't intimidate anybody. i am a gummy bear, a marshmallow. >> you are a marshmallow. >> marshmallow.

i'm a combat marshmallow but i'm a marshmallow. coming up on "lockup raw: ever present danger." the ghastly results when inmates unleash their rage on correctional staff. >> i broke my tv, made a couple shanks and assaulted him. the employee of the month is... spark card from capital one. spark cash gives me the most rewards of any small business credit card. it's hard for my crew to keep up with 2% cash back on every purchase, every day. 2% cash back. that's setting the bar pretty high. thanks to spark, owning my own business has never been more rewarding.

this guy's amazing. when you pour chunky beef with country vegetables soup over it... you can do dinner. four minutes, around four bucks. campbell's chunky. it's amazing what soup can do.

in a prison is a totally unique experience. but things can go to hell real fast. you sort of have to be on your toes. >> i haven't met a correctional officer who hadn't been involved in an altercation or hadn't been stabbed or beat up by an inmate. it's part of the job. >> in the blink of an eye something can go wrong. blink of an eye you can lose your life or be crippled for life. >> you don't know, when you come in here, if you are going home when your shift is over. >> don't trust any of them. none whatsoever.

they're not here for singing too loud in church. >> it really shocked me how cruel and emotionless these people can be. they're human but real hard inside. >> at the holman correctional facility in alabama, we met inmate kenny wilson. he was housed in the prison's administration segregation unit. >> i had about five or six charges. my most biggest charge is dealing with a teenager which i was 16 and she was like 15 i believe. i was dealing with both of them, the mom and the daughter you know what i'm saying? came in 15 years, and i got 15 more. >> originally convicted of rape

and theft, wilson earned his second 15-year sentence while behind bars after he brutally beat a corrections officer. >> ended up, cracked his ribs, his jaw. gave him early retirement. think i did something to his hip and broke his collarbone too. to me it was no thing, it was prison. you don't come here and work here and think it's cake. >> do you regret what happened? >> no. he didn't die. he just won't be a correctional officer no more. >> despite his attitude, some at holman are trying to help wilson turn his life around. >> i have known him several years. he's a young man with a lot of anger problems. he acts out through his anger. that's what we're trying to deal with now. >> i have a bad anger problem, you know what i'm saying? i'm angry because i ain't with my family. i'm angry because of the way they treat you, the things they

do to you. it ain't never a happy day in prison. >> at the time of our visit wilson had just completed an anger management program, that deputy warden patterson arranged for him to take in his cell. >> he needs to grow up. immaturity. he's working on it. >> i got kids, man. everybody going to change one day. >> for wilson, change is essential. since most of his sentence for assaulting the officer will overlap with his original sentence and he is scheduled to complete his prison term and be released in about 18 months. but just a day after we interviewed him, wilson's anger surfaced again. he greeted our crew with an obscene gesture. >> one [ bleep ], y'all, two, retired. we don't need y'all around here anymore. >> some days they like us. some days they don't want to see us.

i think that's kind of a function of being in prison. you are mostly pissed off all the time, anyways. if you can take it out on the film crew, why not. >> though wilson may enjoy his freedom again, it's too late for one other inmate. whose anger has had disastrous consequences. >> my name is jesus garcia, i have been incarcerated for nearly 12 1/2 years. i'm incarcerated for first degree murder and i have life plus 26 years to serve. >> when we met jesus garcia at penitentiary of new mexico he had recently been involved in the bloody assault of two officers. >> leading up to that day there had been incidents where they messed with me. that was the third time. i said, that was it. that's enough. i broke my tv, made a couple shanks and assaulted them. assaulted one of them. i got him, and then another officer came to his rescue and obviously trying to defend myself, i assaulted him, too. >> they were slashed around the

head, neck, came very close to the jugular on one of the officers. >> i remember running into the pod. there was an inmate between both of them and they were both being stabbed. >> aaron bell rushed to aid his fellow officers moments after the assault began. >> i hit the inmate, tried to grab him by the arm and i slipped. and i didn't realize what i slipped on was all blood. >> it took a couple of minutes before we got other officers in there to respond, pull jesus off and get medical attention to the officers. >> i was covered, basically, my neck down, with blood. it wasn't the inmate's blood, it was my fellow officer's blood. >> had that guy not been there to save them. i probably would have killed them. who is to say? if he would have died would i have felt bad or had remorse? maybe. maybe. >> the matter of fact way that he talked about attacking the officers, was really scary.

it made you realize what a -- what a dangerous place a prison is. >> garcia went on to give us a chilling insight into the mind of an inmate bent on spilling the blood of prison staff. >> actually i don't regret my actions that day. it was all to make a point. i mean i could be the nice guy i try to be for all these years or i can be that kind of person. i look at it like this. those guys i did that to, they're people that just don't get it. i mean, there are some people that you can reprimand by words, some people you can encourage. there are other people that you have to beat to death. >> as an inmate, an officer. that's what inmates do. but as a job, and what i want to do for the department of corrections, is to come to work every day. be fair and consistent. and if i were to retaliate against him, obviously i wouldn't have a job anymore. so in hindsight, you have to hold your tongue and go home every night.

next, on "lockup raw: ever present danger." >> when you step out of bounds and disrespect somebody, you better expect that same disrespect back to you. >> cellmates in one of america's toughest prisons, school a "lockup" producer on the art of survival. >> step on a man's foot. may very well go back and show up with a knife and come in and decapitate you. hi, i'm cashing in my points... peggy? no more points - coupons now. coupons? coupons. coupons? next, you convert coupons to tokens. tokens? then you trade tokens for credits. and then i get the cash? then you call back. bye bye.

it was built to handle the toughest of all criminals. its inmate population includes charles manson, robert kennedy's assassin sirhan sirhan and some of the nation's most violent prison gangs. lockup crews have also been frequent guests at california's state prison corcoran.

>> you might have to fight. you might have to stab. you never know. depends on the situation. >> a lot of times it is fist fights out here. but i would say maybe every other month we get a righteous stabbing. when they do stab each other they go for the kill. they don't just stab each other to play around. >> every morning you wake up you are dealing with 1,000 different attitudes. you never know what can happen on that certain day. all you can do is think the worst, hope for the best. >> we met two inmates on the yard at corcoran who are much more pro-active when it comes to surviving life in this powder keg. they gave our crew a tutorial on how they do it. >> the rules you want to live by behind the walls you want to give everybody the same respect that you expect to receive from them. >> without order we have anarchy. when we have anarchy we have people die here. >> robert morales serving 30 years to life for burglary under california's three strikes law.

his cellmate has a 16-year sentence on several burglary and drug related charges. >> you step out of bounds. you disrespect somebody. you better expect the disrespect back to you. you don't know in what amount that disrespect is going to be. you can have words with somebody. you better clean it up later. >> if you step on a man's foot, for instance, this man is doing [ bleep ] the sun doesn't shine, you apologize. he may well go back and show up with a knife and come and decapitate you. it's happen. it's happened. it's happened in prison. i have seen it dozens of times over the 30 years i've been incarcerated. >> they warn that in this yard, jogging around the track can have fatal results if you don't know the rules. >> if you get too close to somebody on the track, you talk, let them know you're there, if you are running and there is a man walking in front of you, you want to yell out "track." he could perceive you as a threat. and turn around and nail you. every man that runs up to me

even my friends i look at their hands the first thing. i don't know if they're going to kill me. i don't trust anybody in here. i don't know if i offended anybody. even my own people. i see two, three of my own people together. i think they're talking about me. what this place breeds, conducive to paranoia. always looking at people's hand. this is prison. you can't trust anybody here. >> can you even trust your own cellmate? >> yeah. because when you live with a person, 24 hours a day, you build up a brotherhood in the sense of, you build up a rapport that you didn't have with your family. and you, you both are dependent on each other for survival. and you have -- there is an unwritten code that if your celly is attacked, then you are attacked. the honor of one is the honor of all. if he is touched then i am involved. and so we are a team. we're a team. we're a force to be reckoned with. so you choose your cellies carefully. >> as their survival depends on their bond, the two men must be

extremely sensitive of each other while living together in a tiny cell. >> the space here is kind of small. no real room to exercise. i come off my bed. i got to step on his stuff in order to get down. so i have to ask him politely to move his stuff if i want to come down off the rack in the morning time. >> we use this privacy curtain that gives you the illusion of being in another room when you have to use the rest room. >> these are not allowed. we make this on our own. >> morales had a final message for those on the outside. he wanted them to know that the danger lurking behind the walls could someday strike close to home. >> society doesn't understand the suffering that goes on behind these walls. i think that the greatest fear that the public should have is that some of these people are going home and if they go home and they're angry young men they have been traumatized, they have been brutalized, they've been desensitized, dehumanized have

no regard for life and when they get out there you are going to meet the guys in an alley one day. if he asks you for your wallet and you don't give it to him he is going to callously pull out a gun and shoot you dead because he's been taught that in here. that, that to be sensitive is to be weak. coming up on "lockup raw: ever present danger." >> i've had serious incidents of fecal matter and urine to where i was placed on aids inhibitor medication. i've been expose today hepatitis. >> an inmate's most vile weapon. portable navigation. a bluetooth connection. a stolen vehicle locator. roadside assistance. and something that could help save your life - automatic help in a crash. it's the technology of five devices in one hard-working mirror. because life happens while you drive.

escaped. no word if ransom was paid. l.a. police have identified the shooter who opened fire in traffic on sunset boulevard this week. they say 26-year-old tyler brem shot and wounded one person before police killed him. more news later. now back to "lockup." due to mature subject matter, viewer discretion is advised. >> 90% of prison life is boring. it is that other 10% that we worry about as producers, the safety of the crew. we take great precaution to make sure we can do everything possible to protect our crews. sometimes they're going to wear stab vests. other times they're followed by a group of correctional officers for protection. >> but there are some things you can't protect against. there's a particular type of prison assault described to lockup crews over and over again. the nature of this assault is not only disturbing, it's disgusting.

we warn you, what you are about to hear is extremely graphic. >> the common way the inmates assault staff now is, what we call gassing. where the inmate will throw a liquid substance on an officer, usually, what the inmates use is a combination of urine and feces. what they do is they will urinate or defecate in a cup, and they'll stir the two human excrements together and they'll let it rot and when staff walks by they throw it in our face. i would say, a gassing assault happens at least once a day here at san quentin. >> seemingly, at almost every other prison we visited. i've had serious incidents with fecal matter and urine to where i was placed on ace inhibitors medication. and i've had hepatitis-infected blood spit in my face. >> they get as creative as

putting feces and urine in a toothpaste tube and squirting it through their door or under their door. those kind of things. >> about 5:45 at night, feeding chow, i was carrying an inmate tray, to feed them. inmate had his flap down, feeding his tray. at that time the inmate had a squirt bottle, water bottle they use on the recommend yard. it was filled with a substance. and when i was carrying trays back down, he squeezed urine into my eye and mouth area. i was checked out, had a tetanus shot done by urgent care in nashville, had a blood sample drawn from me. to see if i had anything or contracted anything from the inmate. i'm worried. i do have a wife at home. my fear is taking something home to my wife and kids down the road. >> this vile form of assault isn't limited only to correctional staff. this inmate works as a rock man,

prison slang for a janitor at the brushy mountain correctional complex in tennessee. >> i work and so i have to deal with individuals who, who have been in a lot of trouble or, i may have to deal with the ones, that is out of their mind a little bit. so some days they may feel like, they want to throw it on me that day or urine. this is what we've got to deal with. even they may feel like they may want to throw it on me that day. so, it's things you got to deal with. >> lockup crews also stay constantly aware knowing all too well they could wind up in the line of fire. >> in my mind that is one of the worst things that could happen. we were shooting san quentin, alpine section, down on the ground floor. and, suddenly i felt something hit me on the top of my head. and i had the worst thought, oh,

my god i had just been gassed. luckily it turned out to be a banana peel. >> when we visited the stateville correctional center in illinois, we encountered another bizarre practice involving human waste. >> feces, spreads it on everything. clean it off every day. every day he puts it right back on. >> in the segregation unit at the stateville correctional facility. basically this is where they have people, being extra bad in the facility come and be locked up. they urinate, bowel movement everywhere, i think they just kind of have gone crazy, prison life is probably getting to them. >> but we have never seen a more bizarre display of the gut churning activity than at california state prison corcoran. it happened during a routine shoot at the prison hospital. >> we were there for like ten minutes. did a couple interviews with a couple doctors. initially it seemed like it was

going to be mundane and going through the process. so we decided to leave. we were all packed up ready to go back into the other section of the prison when all hell broke loose. >> we have four inmates in four different cells that are holding food trays, some have started flooding the tier which means causing the toilets to back up and causing water to come out onto the floor. i'll first go out, try to talk to the inmates and trying to get them into compliance. if the inmates fail to comply we'll probably have to extract them. >> one by one the cells just started popping off. you know, one guy is just started throwing feces, the other guy was covering up his cell. i was like, wow, this isn't boring. this is pretty intense. >> i am going to talk to them. want to make sure we get that on video. at that time, if the inmate doesn't comply we are going to go and use the gas masks. i want everything ready to go in

no more than five minutes. everything ready to go in five minutes. >> knowing they might be exposed to human waste, correctional staff suit up in plastic cover alls to protect their clothing >> they don't make them big will secure any inmate who staff's

it's probably the most common of all emotions inside prison. and fear comes in many forms. as a group of inmates at kentucky state penitentiary explain to us. >> i don't fear none of these guys out here. the one i fear the worst is probably -- it's not a clique, my friends that i hang with, these 10, 15 people. i probably fear them most. because i know who they are. the rest of these guys i don't fear none of them. i hope they watch this. they all know the ones that don't.

they all know they probably do anyway. >> only thing i fear is the end, i believe that's what's going to get me in life. this old cigarette, catching cancer and kicking the bucket. >> just because i don't fear doesn't mean they can take me out. if he fears you that's when you got to worry. in here especially because they'll sneak up on you with a knife, a rock, a choke, whatever they want to do. they will get you because they fear you. >> to me, he's more dangerous than a stone cold killer. you know, he is scared. you know put himself in a situation where he is in the corner. >> that's his only way out. >> and no group of inmates feels more cornered than sex offenders. rapists and child molesters are the pariahs of the prison yard. >> as far as i'm concerned they can die. when they get around me and start talking and think it's okay to reveal they're child molesters every time they say that i am going to smash them.

>> most sex offenders choose between a life of constant threats or to serve their time in highly restrictive protective custody units. but mark higgins takes a different approach. >> my crime is -- is a serial rapist. i was convicted of several different charges of rape, attempted rape, nine assorted counts in all for a total of 35 years. >> we met higgins at riverbend maximum security institution in tennessee. on the outside, he had a professional career and lived in a wealthy nashville suburb with his wife and four children. but he lived a secretive double life, and as he carried out his string of attacks against women between 1990 and 1995, the media dubbed him the gentleman rapist. >> the feeling we had on the crew was, wow, that guy is really scary. he certainly is not, you know, didn't appear dangerous or, your

stereotypical inmate, but, you know, i think that's what made him really scary was that he was like your neighbor. the president of your city council or your best friend. i think that made it all the more creepy. >> rapists such as myself, pedophiles, people that murder children or women, they're at the bottom of that pecking order, okay? and there's a lot of men that will take advantage of your crime to try to manipulate you into doing something you don't want to do, be that giving them sexual favors, food from the commissary that you buy, different things like that. at the end of the day we're all wearing blue jeans with a white strip on them. we're all in prison for a law we've broken. >> unlike most other sex offenders, higgins has stood up for himself. >> if someone wants to make a big deal about my crime, i'll turn to them and look them in the face and ask them, what exactly do you want to know

about it? if this person thinks he's going to try to control me by holding that over my head, he's just made a terrible mistake. because i will absolutely confront him on that. and, oh, by the way, what's your crime? is that really better than -- do you have less of a victim than what i had? you're in here for murder. at least my victim is still walking around, living and breathing. >> one reason higgins can get away from defending himself is because he's housed in a minimum inmates have similar charges. iowa's anamosis state

correctional officers are well aware that some inmates pose a near constant threat and that many of them will be incarcerated until the day they die. but "lockup" crews have found that it might take more than death to keep some inmates down. >> i love a good ghost story.

and anywhere i go that it looks like it has the potential, i'll always ask, do you have any ghosts around? in new mexico they had a lot at the old prison. >> when we shot at the penitentiary of new mexico, major dean lopez took us to the old main. a now abandoned building that used to be the heart of the prison before it was replaced with a state-of-the-art facility. >> this is where most of the murders from the riot took place, was this cell block right here. >> this was the site of a 1980 riot. they slaughtered 33 of their own. reminders are everywhere. >> an inmate got chopped up with an ax. what you see here on the floor is indentures and ligature marks where the ax went through the body and carved into the floor. >> one other remnant of the riot is just as grisly but has also been the source of an unexplainable phenomenon.

>> they burned a guy to a crisp down here. it doesn't matter what we've done to try to cover that up. we've tried industrial gray paint, floor wax, stripper, everything. we paint it. within a month and a half, this whole burn mark would be back on the surface of the paint again. >> some people would look at this and say that's the ghost coming up through the floor. >> there's been a lot of things that certain people have seen in the old main from the time that it was open, i mean, at one point in time we had no electricity in this place and we'd find lights on. then we'd get to the facility and the lights would be off again. no explanation for why they'd be on. you'd hear noises that people would say were people screaming. i'm not very much of a superstitious person and i believe that everything has an explanation. as a matter of fact, i was one

of the people they'd send down to investigate those noises. there are some things i've seen here that i've not been able to if somebody else can, i'd be are unexplainable. >> the specter of inmates refusing to leave prison, even after death. "lockup" crews have found that at other prisons, too. built in 1852, california's san quentin is one of the oldest prisons we visited. >> approximately 1985 brand new correctional officer here at san quentin, i was working graveyard in a section called donnor. >> officer feudler is a member of san quentin's investigative services unit, an elite team of cos that track gang activity and other threats to the institution. >> one night my partner and i were working graveyard. i was sitting with my back to a file cabinet just like this. there were a row of padlocks on the top handle.

my partner and i were talking. all of a sudden, the locks started rattling back and forth together. clacking. he looked at it. i looked at it. see, i'm getting goose bumps just thinking about it. we both ran out of the office. and we had no explanation as to what that was. we asked some other officers and they said that, you know, the unit's probably haunted. never can tell. there was no explanation for it. no earthquake. the inmates weren't complaining in the unit about the ground moving. there were no wild animals in there. i didn't bump it, he didn't bump it. no telling. >> there's been a history of other strange phenomena here as well. >> this is the san quentin dental clinic. back in approximately 1984 there was an inmate murdered here in this corner. late at night, our officers working in here have heard the

same thing i've heard, footsteps walking in the floors above me right here. and i keep telling them that the guy that was killed here, the inmate, that's him still walking in this building. >> how do people react? how did you react when you first heard it? did you go up and look? >> absolutely. i thought somebody was in the building. so whether or not i didn't know whether or not it was an inmate or another officer. when i walked upstairs, everything was locked up, i no longer heard the footsteps. came back down, continued my work. got quiet again. heard the footsteps once again. and everybody in this unit has heard them late at night. >> with so many inmates bent on destructive behavior, it's no wonder that some would, if they could, carry on, even after death. because in prison, danger never dies.
