they've all encountered one absolute certainty. >> we film in extreme environments. most people would never want to step inside a maximum security prison and yet we send our crews inside some. most dangerous facilities in america. >> you can't let your guard down, you have to keep your eyes open in the back of your head. the hairs are constantly up on the back of your neck because they're violent places and violence can and does break out at any time. >> our cameras have been there to capture the dramatic life-and-death contacts.

>> california state prison corcoran, home to hundreds of the state's most violent and infamous offenders, host the lockup crew in 2000 and 2005. >> right before i walked in, i had to sign a document that made me think twice and it basically said that in an event that there is a hostage situation inside the prison walls, they will not negotiate for your life because you know the risk that you're taking when you walk in. while at corcoran, you constantly hear has to alarms going off. you're never sure what's going to happen in this place. but then when up hear those alarms and everyone dropping down the ground and you got those rifles peering out of the towers, it takes your breath away for a second.

>> those the incidents are oushl brought to a stop in minutes, they always pose serious dangerous to the officers and our crews. >> we were doing a pretty much routine cell search. it was a very controlled environment. then right in the middle of it, we heard the alarm and we just saw the guards. the guards didn't even save anything to us, the c.o.s. they just started sprinting. so i'm like, i'm going.

>> inmates know when the alarm sounds, they're required to lie on the ground. otherwise officers might see them as combatants. >> a whole yard of about 600 inmates were completely down on the ground. >> what just happened just now? >> two guys westbouanted to hor and get a little bit heavy. if we let that happen, there's a possibility they'll stop fighting and other people could get involved. >> our encountered a different situation in pelican bay. >> having a routine guard release. >> our producer was conducting an interview with lieutenant ben

grundy while a second camera unit was down below. then suddenly -- >> there's an alarm in that building right there. we need to leave. >> our cameras search for any sign the trouble is spreading outside to the actual alarm. >> nobody's waving us off yet. something is going on inside the building. >> what might be happening? >> probably an assault on somebody coming out of their cell. >> officers subdued six inmates involved in a fight. one was slashed with a home made weapon. fortunately this indent was nothing like the deadly events of february 3, 2000. >> on that rainy day, many were

wearing rain gear, not only as protection from the elements but to hide dozens of homemade weapons. it was the beginning of california's worst prison riot. >> doug burrell and dozens of his fellow officers tried to subdue inmates with pepper spray and teargas, but every time it seemed the staff had the situation under control, another fight broke out. >> it looked like the movie "braveheart," the fight scene in "braveheart" but it was the real deal. >> they started firing shots. so everybody that wasn't involved in the riot laid on the

ground. >> even the gunfire raining down from pelican bay security towers did not quell the riot until one of the inmates was killed. 15 others were wounded. >> after we were done, i was cleaning blood off the walls and off the floors and benches in here for a good hour. >> pelican bay's worst riot was fueled by the inmates' impulse for violence. and many of those inmates ended up here. the security housing unit, or the shu. >> inmates that were placed into the shu housing unit were placed in here for the most part because of violence. that violence could be against other inmates or against officers. >> it was here in pelican bay's most secure unit that we came across perhaps the prison's most dangerous inmate. >> my name is scanvinski hymes. i got the name from my mother. she wanted me to have the name no other black man in america would have. >> hymes was originally sent to prison for possessing a weapon in a youth facility.

at the time our cameras profiled him in 2000, he had been locked up for more than 12 years, almost half his life. >> everything is the same. nothing really changes too much. i mean, wake up in the morning, eat breakfast, go to the yard. when i get bored, i got -- i got to get into stuff, you know? >> the stuff hymes most frequently gets into is provoking officers to extract him from his cell. each inmate is assigned a security risk classification score based on his disciplinary record. the average score ranges between 19 and 27 points. >> i probably have the highest classification score in this prison system, i'm over 2,000 points now. i have caught over 30, almost 40 felonies in prison. you know. various staff assaults, stabbed, anything you can think of. only thing i haven't been convicted of in prison is murder and drugs.

>> so now [ bleep ]. [ bleep ] [ bleep ]. >> hymes is probably one of our most difficult behavioral. he will tell you to your face his agenda. his agenda is to fight you every chance he can. >> help, help, help! ha ha ha! ha ha ha! >> he'll watch you and his hope is that you will make a mistake so he can either get out or fight with you. that is his plan, that's what he does 24 hours a day. >> every time i see them, it's to make their eight hours as stressful as possible. >> inmate hymes, we need you to turn around -- nope! >> nope. i'm not going to turn around. you know, whatever that may be, be making noise all day. whatever i can do to make their eight hours as stressful as possible. they say, well, i'm going home, i'm going home. but, yeah, when you go home, you'll be back tomorrow.

>> close it. close it. >> hold it. >> hold it. >> come on. >> [ bleep ]. >> that's the thing about this place. well, kick me out of prison. if they don't want me here, kick me out. >> eventually transferred to san quentin state prison, the man who is arguably california's most violent inmate completed his sentence and was released in 2007. >> you have people locked up in this, this type of environment and then you release them to the street. what do you expect? >> back up, mother -- ha ha ha! next on "lockup: raw." >> they'll come across their enemy, slice them across the neck. >> the ingenious weapons inmates use to attack. and the lengths officers will go to in combating them.

every day in america's prisons, correctional officers are searching for them. >> a lot of these weapons were confiscated on the yards. >> in prison slang they're known as shanks. they're the deadly weapons inmates create from behind bars, with an ingenuity that almost defies imagination. >> what they'll do is get a disposable razor, put both blades, one on each side of the toothbrush. they come across their enemy. and slice them across the neck. because the two blades are so wide apart, it just filets the individual wide open. >> inmates will do almost anything to hide the weapons they spend so much time

manufacturing. >> the first one looks like a wire shank. these are all covered or wrapped in some kind of latex material and then lubricated with whatever they can find. >> how long can they keep it up there? >> i believe the average time is about a day. but when it's time to pull it out, sometimes it won't come out and it leads to other problems. >> because inmates go to extreme lengths to fashion and conceal weapons, officers must be outfitted with a high-tech, nonlethal arsenal of their own. our cameras were rolling at riverbend maximum security institution in tennessee as correctional officers practiced firing 50,000-volt tasers at inanimate objects. then the demonstration moved to other targets, their fellow officers.

>> how did he get chosen to be the lucky guy? >> he volunteered. >> i'm a glutton for punishment. >> are you ready? >> aagghhhh! [ bleep ]. >> are you all right? >> uh-huh. whoa! >> you okay? >> yeah! >> at the los angeles county jail, we encountered inmates who seemed impervious to tasers or anything else. to control these inmates, deputies had to resort to what's known as a four-point restraint. >> in the inmate reception center, there's a lot of incidences, these guys coming straight off the street. they're angry and they're very violent. and they often go off. >> everybody else sit down. >> sit down.

>> one inmate in particular just couldn't deal with it anymore. he went completely berserk. >> move it. >> freeze! >> move it! >> have a seat. >> and they had to restrain him. and one of the ways they do that is these four-point restraints. and they tell him exactly what they're going to be doing. >> mental health staff has ordered you to be placed in four-point restraints. you understand that? >> yeah. >> i'm going to put you in here, i need your cooperation. the more you cooperate, the faster you will be out of points. >> sergeant gilbert duran supervises the carefully choreographed restraint process. >> the deputies have already been briefed as to who will take the upper body, who will take the lower body extremities. sometimes it takes a couple of extra deputies to hold the upper body if they're struggling or

really upset about what's happening to them. and about how many four-points are done per week? >> we average up here -- on day shift and p.m., probably anywhere from three to six a day. >> as extreme as four-point restraints are, inmates sometimes take an equally extreme measure to attack officers. one that is particularly vile. >> gassing is what we call it. it's a mixture of feces and urine sometimes fermented for days until it stews into something that is so grotesque that you can't mention it. >> during his 14 years on the job, san quentin officer jones has never had a worse experience than being gassed. >> i would rather be punched, rather be kicked, rather be stabbed than to be gassed like i was back in '92. >> we have never heard a more

extreme account of gassing as the one described by kentucky state penitentiary inmate, fleece johnson. >> i asked everybody on the wall to [ bleep ] in a bucket. send it down to me. and i would take, two, three, light bulbs, put it in some toilet paper, step on it, break it in some little fragments, put it in there. so when i throw it on them, they wipe it, it will cut into them and get in their blood. and i was standing there with a big old bucket of it and throw it in their face. they would just go nuts. and so the corrections finally made a law that made it a felony. and then that's when i stopped. coming up on "lockup: raw."

the most violent confrontations behind bars. cell extractions. >> they tell you to back up to the door. if you back up you're a bitch.

some of the most dangerous confrontations in prison happen when correctional officers are forced to extract an inmate from his cell. extractions are carried out by specially trained teams of correctional officers according to exact guidelines. >> i'm officer allen. i'm the number three man for the team. i'm responsible for controlling the inmate's left arm. i will use the least amount of force necessary. >> the entire process is carefully choreographed and videotaped for the protection of officers and inmates alike. >> come to the door! >> [ bleep ]! [ bleep ]!

>> when we visited the kentucky state penitentiary, we met inmate dwayne harper, who had a long history of forcing officers to extract him from his cell. >> [ bleep ]. i fight sometimes. i argue with the guards. but i'm not violent. you know, i've done a lot of time. i've been doing time on and off since i was 12 years old. >> when we first met harper he was serving his third year in administrative segregation or solitary confinement for having assaulted correctional officers. >> in my opinion, duane is a really stressed-out individual. >> strip everybody out for talking. don't just strip me out for talking! strip everybody out for talking you racist old [ bleep ]! >> shortly after "lockup" arrived at kentucky state penitentiary, officers had to extract harper from his cell

again. >> he threatened us with throwing feces on police officers, spitting on us through the door, he threatened our families. >> a lot of the older ones like lieutenant gill, all of them, they know me from when i was a youngster. back down here. so we have a different type of communication level and understanding. >> every night you are going to go through this. you hear me? every night you work, honky, you racist, redneck, no good [ bleep ], [ bleep ]. >> harper will serve at least two more years in segregation. >> i made things hard for myself. i been in segregation three years. i don't blame nobody else. because i had an opportunity to get out of here. i let my anger and things get to me that i shouldn't have. and as a result of that, i'm still here. >> i can't say i'm sane.

i'm pretty off balance, but i keep it in a certain amount of control. >> another inmate at kentucky state penitentiary who is no stranger to cell extractions is victor hiatt. prior to interviewing him, our producer was duly warned. >> victor hiatt is a very, very dangerous individual. probably the most dangerous individual in this institution. >> i remember watching victor being led to the interview. and he had such an intense security detail that it almost felt like i was about to interview hannibal lecter, quite frankly. he was cuffed behind his back. but i'll never forget, it was like a normal, fiberglass and metal cafeteria chair. there was nothing special about that chair. and he wasn't chained to the chair itself. the chair was not secured to the ground in any way. i start to think to myself, here

i am about to interview this guy. i'm knee to knee with the most dangerous man in the state of kentucky. and he's not chained to anything. all of a sudden all of my questions, everything i prepared for the interview, went completely out of my head. >> victor, tell me what, originally what your crime was that brought you to kentucky state penitentiary, how long that sentence is, and then how long of that sentence you have served? >> i'm in for murder. life sentence. convicted in 2001. >> are you proud of that notoriety? i mean, we've heard you are one of the most dangerous guys here. how does that -- >> that's what i hear. i'm actually one of the most laid-back guys here. >> as all officers, i've received threats from different inmates for bodily harm. he's the only one that's actually ever tried to follow through with it. >> come on in!

i'll show you what a redneck can do! >> hiatt's refusal to cooperate with officers has resulted in numerous violent cell extractions. >> they tell you to back up to the door. and if you back up, you're a bitch. if you make them come in and get you, you get a little bit more respect. i've never backed up yet. >> take him down. >> well, you knocked about four of my teeth out. it takes a lot to put me at that point. but when it gets to that point, i kind of go blank inside my mind. i get like tunnel vision. and you have to expect to be killed at any time. next on "lockup: raw." our producer witnesses a vicious prison attack. >> i look down and saw these two younger hispanic guys kicking him in the head.

later -- >> he threatened to kill everybody out there, staff and all. >> an inmate goes too far in a confrontation with staff. >> i can't get along with people too much, especially when they're evil. can be yours for... twenty grand? -no! we are giving it away for just 3 easy payments of $4.99 plus tax! the lines are blowing up! we've got deborah from poughkeepsie. flo: yeah, no, it's flo. you guys realize anyone can use the "name your price" tool for free on progressive.com, right?

with lockup, we film in some of the toughest prisons in america. you never know what's going to happen. there's always a chance that violence may break out. >> we found of that the case when we visited california's legendary folsom state prison. >> you can feel it. it's like electricity in the air. it's so thick you can actually breathe in the tension. >> in the blink of an eye in that much time it can change. because there is the real threat that an attitude or temper can change in just a moment. >> and tempers did flare while our cameras were in the yard. >> we'd just gotten done interviewing, basically, a prison preacher. >> i'm a born again christian, and i believe that everybody should know the lord.

if you don't know the lord, i encourage you to know the lord. >> i'd just gotten done putting the camera down. my cameraman was walking around. and then i started hearing a bing, like bing, bing, bing. literally five feet away i see this man probably in his late 50s, early 60s, and i look down and i saw these two younger hispanic guys kicking him in the head, like, repeatedly, and his head was bouncing off this pole. >> what you saw here today was actually a battery. they were stomping his head. you can see he's pretty -- pretty messed up. >> the inmate who was attacked survived because of a quick response by staff on the yard. his assailants were sentenced to six months in folsom's administration segregation unit. some of the most violent gang attacks have taken place here at california state prison corcoran's security housing unit, or shu. we visited the shu's now-vacant exercise yard, which has been

the scene of some of the prison's most brutal violence. ♪ >> i could see why fights went on in that exercise yard. because it was literally like a cage. there was nowhere for you to go. and if you really wanted to take someone out, that was the place to do it. it's literally -- like the most extreme ultimate fighting thing you would see. >> correctional officers showed our cameras how they quell the violence with an arsenal of their own. one that includes nonlethal and lethal weaponry. >> get down! get down! >> the first rounds we fire are wood blocks. hopefully the hurt will make them stop. if we really have to escalate with our nonlethal options, we use what we call a scat round. which is really irritating.

see, those ar little bit louder. the smoke you see there, that's cn gas. it's no fun. it messes up your sight, makes you, you know, makes your snot roll. and of course, we have a lethal option. we have a mini-14 here, .223 round. we use that as a last resort. >> today, california state prison corcoran no longer has to resort to drastic measures to control violence in the shu yard. they closed the yards down and now inmates exercise in walk-alone areas called the cages. but even when officers are able to quell violence, sorting out its cause can be just as difficult. as our crews found out at the spring creek correctional center in seward, alaska. >> slow down. slow down, mr. seiko, slow down. >> blood on the floor over there. blood pathogens need to be cleaned up. >> mr. seiko, you need to respond to me. so we know you are all right. let's go a little bit more. okay.

okay. >> joel brooks is doing 12 years for assault. his adversary, john seiko, is serving a six-year sentence for sexual assault. our cameras were there when officers interrogated them about the fight. >> what was this all about? >> well, he's a rapist. i was talking with an inmate in the meal line about it with him. >> you were talking about his crime with a prisoner. >> yeah, yeah. >> okay. >> i was talking with a prisoner about him being a rapist. he came up to me and he said, you ain't [ bleep ]. and i said, you're not. >> i told him to stop talking about me and i repeated it. and he said, what are you going to do? and i repeated it again, stop talking about me. and then he walked up to me in my face and said, now what are you going to do? >> five minutes later he bum rushed me. >> don't come at me. >> slammed me against the wall. >> i put my hand in his face. i don't know what i did after that. >> he starts scratching my face.

i grabbed him around the waist and threw him on the floor and hit him twice in self-defense to get him let go of my neck. i got a hundred witnesses i can bring up at d-board. i'm not worried about it. >> about him hitting you first or you talking about him and starting it? >> about him hitting me first. >> okay. you've got witnesses about him? >> yes -- >> hold on i'm talking, you're not. do you have witnesses that you were talking about him? >> well, yeah. >> to start this? >> well, i didn't start it. he -- he -- >> we'll figure that out in d-board. do we have the camera? because he's going to be back there awhile until we get him calmed down. strip him, lower body over there. any more marks. >> the bottom line is he hit me first. that's what it comes down to. >> i think it's the bottom line you were talking about somebody else. >> so what? >> how about he starts talking about you. >> so does that give him the right to hit me first? i didn't think so. >> well. >> don't, don't move. >> whoa.

whoa. >> what, you think you're a bad ass, too? >> no, not at all. >> then don't cop an attitude. >> i'm not -- i'm not copping an attitude. >> [ bleep ] punk. >> i'm sorry, what? >> you heard me. >> no, i didn't. >> you better. >> i didn't hear that. >> after the hearing the disciplinary board ruled that he had been provoked by repeated taunts. while seiko wasn't punished, brooks got 30 days in solitary confinement. >> prison is something that you will never get over. it will always stick with you. and even though i don't have life, but one moment of anger is a lifetime of misery. because prison will always stick with you. coming up -- the victim of one of the most brutal attacks ever profiled on "lockup." >> the doctor said, i don't know how much more you could have taken. >> an officer faces her fears as she returns to the scene of the crime. tomorrow starts today. all across the state the economy is growing,

over the years, we've learned that attacks on officers are an all-too-frequent occupational hazard. when we visited indiana's wabash valley correctional facility, officers in the security housing unit were dealing with the latest in a string of violent incidents involving convicted burglar, douglas mccombs. >> since he's been inside the shu, he's been on strip cell. when you see the offender coming out of his cell only wearing his underwear, at that time he was on a strip cell. i think at that time it was for resisting staff or trying to assault staff before. we have had trouble with him on about every range we've put him on so far. >> i can't get along with people too much. especially when they're evil. >> one of the people mccombs

claims was evil, officer sachen. >> an average day in the shu can be pretty mundane. you have recs and showers to do. chow to serve, md sick call, so on and so forth. some days like today get a little more exciting. we had an offender who became belligerent in the shower. >> the offender was mccombs who told us he had good reason to be upset. >> try to get me to take a shower. but they don't have no soap or nothing. i said, ma'am, i just came from the other side, it was nasty where i come from. i need something to wash, a bar of soap. she's talking crazy to me. right? okay? she come up here and talking to me and started, talked to me, well you [ bleep ], you called me a [ bleep ]. and i said, what? i said, wait a minute. i said, i just asked you for some [ bleep ], and i snapped on her. >> he threatened to kill everybody out there.

staff and all. when we tried to get him to come out of the shower, he was refusing, and started throwing toilet water on myself and several other staff members. >> i got it all through my face. all down my back. it was toilet water. >> our cameras were present when mccombs was moved from his cell. but because he is so dangerous, we were restricted to shooting from the unit's security center. >> i don't need your [ bleep ]. i'll take some [ bleep ] and i'll be your ass every time you come [ bleep ]. your mother -- >> easy, easy, easy, easy. >> we put him on the wall first. put him on the wall, face the wall. we want him face the wall. we don't want him turning his head, getting mouthy. that's when you get spit on. we want his nose to the wall. i don't want to talk to him, he can talk to the wall. >> face the wall. turn around. face the wall. >> [ bleep ] sit up there and talk to him.

>> face the wall. >> why don't you [ bleep ]. [ bleep ] i'm tired of your [ bleep ], [ bleep ], [ bleep ]. >> stand still. >> mccombs freely admitted to our producer by the time the officers put him back in his cell he was looking for any possible way to hurt them. >> i just grabbed some [ bleep ] water out of the toilet, started bombing. i am just getting tired of what is going on with these people, man. if they don't get me out of here, then i probably will -- might end up killing somebody or they might kill me. >> today, mccombs remains incarcerated and has been transferred to another state prison. >> i figured that if it was going to happen, it would happen within the first year. >> in 2004, karen talley was in her sixth year as correctional officer at indiana state prison when she was so brutally attacked by an inmate, she nearly died. we met her two years later.

>> you know, they all know me. the guys know me. i used to work in the intake unit when the new arrivals would come in. they know me. i'll be all right. never imagined it for all these years later. never imagined it. >> at the time of the attack, officer talley was responsible for supervising "b" cell house. an important part of her job was securing the inmates back in their cells with a system called rolling of the bar. an older, manual cell locking device. >> that day, chow lines had run late. i said, come on, guys, go in your cells. you miss roll-in, you know what happens. i figured all of them would be in. i rolled the bar. bigger than anything, here is three of them didn't make it. so i went down the range. i started at the end and worked my way up. the last cell that missed roll-in was 424. i locked his door. went to 418. locked his door. went to the next cell -- 410.

i said, come on, go on in your cell. he said, i'm not going in. >> officer talley alone on the tier with the inmate says she knew immediately she was in trouble. >> at that time, a sick feeling just overcomes you, and you think, wow, something's not right. so i called for my sergeant on the radio. he said, it'll be a minute. and the guy just hit me. both of my eyes were busted right in the eyebrows. i had 50 stitches in my eyebrows. he broke my jaw. it was broken in two places. the doctor said, i don't know how much more you could have taken. had he kicked you one more time, he could have killed you. without a doubt, you could have died. >> close three. >> her attacker received an additional ten-year sentence for aggravated battery.

and after recovering from her injuries, officer talley took the brave step of returning to work at the prison. this time, monitoring the trucks that deliver food to the facility. she no longer has any contact with the inmates. >> in life itself, within seconds your whole life can change. in a prison environment, sometimes it doesn't even take seconds. in the blink of an eye it could be over. >> you're all right. you're okay. >> the day after her interview with us, talley surprised our field producer when she said she was ready to return to the cellblock for the first time since the attack. >> keep your chin up. >> escorted by officer chris st. martin and our crew, the return proved to be far more emotional than she could have imagined. >> there you go. safe and sound. want my chair? take the big black one. >> can i have some -- >> yeah, you can. sit down.

sit down. there you go. >> though returning to the cellblock was difficult, talley told us it was also cathartic. >> yeah, i was down for a while. but i'm not dead. they didn't kill me. i'm okay. emotionally, i'll heal someday. and the sleepless nights and the worry and the wonder, "oh, my god, is this ever going to happen to me again?" i've dealt with most of that and it's really a hard thing. next, on "lockup: raw," an inmate turns violent against himself. >> i swear i'll break my neck [ bleep ]. yeah, i love pain! yeah, yeah! if they could ever catch you.

interview, etter got into a verbal confrontation with a female correctional officer that quickly escalated. c.e.r.t., the correctional emergency response team, was called in to extract him from his cell. >> d-11. he's been banging his head on the door, spitting on the glass. refusing to move or comply with any orders. we have permission to use force to extract him from his cell. >> for security reasons, the prison videotapes all extractions. >> you ready to move? >> put your hand out. other one. >> a mask is placed over etter's head to prevent him from spitting. >> let's go. >> initially he seems to be compliant. but as they pass through the doorway, etter explodes. >> oh, hey, hey, hey. >> [ bleep ] [ bleep ] [ bleep ] i swear to [ bleep ], [ bleep ], break my neck, break my neck! i swear to god, break my neck. yeah, i love pain!

yeah! yeah! >> etter, stop, stop, stop stop. >> [ bleep ], yeah, hurt me more! >> etter's secure. etter, let's walk. no more banging your head. understand? >> i'll kill you all. i'll kill you all, you [ bleep ]! you understand? i'll kill you all! i'll kill you all! >> etter. calm down. >> hey, calm down. >> put him down. >> on the floor. >> all right. >> got his legs. >> all right. easy. >> hurt me more, hurt me more! ow. ow! let's go up. stand up and walk normal. >> etter. etter! >> as his fit continues, etter is taken to the suicide prevention unit for observation. >> [ bleep ] come on, hurt me more! hurt me more, do it! >> nobody wants to hurt you. >> why are you [ bleep ] and smashing me against the wall if they didn't want to hurt me, huh?

>> to prevent him from harming himself, etter is placed in four-point restraints. >> lay back. lay back. >> our cameras were there the next morning when a nurse came in to check on him. >> etter, are you feeling like you still want to hurt yourself? >> i never wanted to hurt myself. >> now, were you banging your head last night? >> yes, because i was frustrated. i do that when i'm frustrated. >> that's not the right thing to do though, is it now? >> it's better than hurting somebody else. >> well, you're right. what i'm going to do now is i'm going to call the psychiatrist and see if we can just discontinue the four-point order so he doesn't even have to go back into them now. i really don't feel he's any threat to himself or others at this point. >> released from the four-point restraints, etter is moved to a 24-hour observation cell and is placed in a suicide smock.

a tear-proof gown to prevent him from hanging himself. our crew later accompanied the nurse when she asked etter to relay his version of what led to the extraction, the confrontation that he'd had with a female officer. >> she started antagonizing me at my door. i said, get lost. get the [ bleep ] out of ear. i don't like you, i don't want to talk to you. she made a smart-aleck comment. i smashed my head on the door. i said, you see that right there? next time it's going to be yours. i said, get the [ bleep ] on. and then i spit on the window. i said, that's what i think of you. you're nothing but trash. i said, get the [ bleep ] gone. she started [ bleep ], saying, at least i ain't some meth-using, something like that. i snapped. i said, you know what? you want to go there, i will have someone on the outside pay you a visit and it will [ bleep ] and rape every one of your kids and kill you, how do you like that, bitch?

i said, bring that [ bleep ] up. i said, you don't [ bleep ] go there. >> four days later, etter is released back to his cell. >> you seem to be doing a lot better to me. i hope you feel you are. >> yeah, i'm doing better. >> i'm glad to hear that. just keep it up. >> i just get real frustrated. i react off my emotions. i never think ahead -- i never plan ahead about what i'm doing. >> etter has since been moved to iowa state's maximum security unit due to ongoing disciplinary issues. while nobody can tell if he will hurt himself again, etter still feels it's better than the alternative. >> i've learned to take my aggressions out on myself instead of other people, you know? it might be the wrong thing to do, but you know, i've learned hurting other people will just get you in more trouble than it does hurting yourself.
