behind the walls of america's most notorious prisons, into a world of chaos and danger. now the scenes you've never seen. built in 1852 and home to california's death row, san quentin state prison was bursting at the seams due to overcrowding. when we shot our extended stay series, san quentin had a program designed to discourage troubled teens.

through the program, they shed their experience with teenagers who already had run ins with the law. >> close the gate. >> what we need you to understand, you in san quentin this morning. you are in a place no kid should ever want to be in. you should be out playing in the park. you here because of something you did. >> what is your name? >> angel. >> angel? >> yeah. >> how old are you? >> 13. >> 16. >> jonathan, i'm 16, too. >> you have the opportunity to leave out of this place and never come back. >> let me introduce myself to you guys. my name is david. i'm about to be 25 years old. i have been in prison since i was 15 years old for murders. >> david monroe is serving 15 years to live after having pled

guilty to murder. >> i banged before. i been on the streets before. i'm from stockton. i did it all, all of it. everything you did, everything you did, we did it. it's just about us not scolding the kids. it's not a scare straight, but we try to give you the communication like look thrks is what i did and this is where it got me. this is the trophy i tried to earn. do you want to come to jail at 15 years old? do you want to come to prison and be on the yard? stand-up. let me see how tall you are. this was me. >> my size? >> this was me when i came to prison. i was 15. they look at me like, are you serious? 15 years old, they locked you up? can they do that? >> at 15, monroe's involvement in gang violence changed his life forever. >> they say you have a gurney,

preview of the stark conditions they might face if they ever enter the california prison system. >> i want you to get a good look at this restroom. this is where you are going to use the restroom. look how they take care of this place. do you want to use this restroom? you come to prison, this is what you are putting yourself in. you have no privacy. that's what you are coming to. >> what i got out of it is i don't want to end up in jail. i have to start watching what i'm doing and make better choices. one messed up choice could ruin my whole life. >> the thing i learn is a whole lot of stuff. it ain't a good place to be. >> it has to come within you. you have to change. >> this is for my victim. i can't give him his life back, but i can save somebody else's life because of what i did. i hope this family knows what happened to him is not in vain

anymore. some people are being saved. >> take care. hopefully we don't see you again. that's the hope, we don't see you again. >> san quentin is one of numerous prisons and jails where inmates and staff provide cautionary tales for troubled youth. at the suffolk county jail in boston, massachusetts, we encountered another program called jailbreak. >> remember, when you visiting here, you are going to get experience of what it's like to be in jail. make sure you take everything out of your pockets. hat. take your hat off. show respect. take everything out of your pockets. >> when we film in a prison or jail, we do our best to be a fly on the wall. in the case of jailbreak, you know, these kids came in and, yeah, they were definitely aware of the camera. >> are you scared? are you scared?

how about you? >> no. >> you're not scared right now? >> no. >> there's no reason to be scared, to tell you the truth. >> i don't think it was necessarily the camera that affected them in the way they had an attitude or brava toe. i think it was relating to age. >> everybody stand-up. right over there. right now, all you have to do is empty your pockets, take your jacket off. nothing should be around your wrist, in your ears or pockets. everybody over here. put these uniforms on over your clothes. hurry up. >> these kids are from the boston public schools. they were suspended from school because of something that they did. >> tuck your shirts inside. everybody tuck your shirt inside. >> once they have the uniform on and start yelling at them and talking to them in a way they know i'm in control, they don't know what to do so they break down. you are 12 years old, dude!

12 years old and you want to cut somebody, assault somebody. keep your mouth shut. >> 16-year-old damon pope, however, who recently was caught with marijuana, appeared determined to not break down. >> you are in jail right now. 16. you'll be 17 in a month. you have this attitude like you are too good to be in this place. you are going to run this place. are you kidding me? are you kidding me? you think you're that good? >> tell me about your goals. >> my goals, trying to entrepreneur, you know. possibly take over this jail, you know? be at home like donald trump, collecting money, writing checks, possibly writing you a check. you know? >> that sounds great. >> i tell you what your goals are. get in one of these unit ifs you continue to do what you are doing. in a month. i give you less than that. you are 17 years old. you will not leave. you understand me?
