good evening. thank you for joining us. violence in prison is on the rise. one sheriff is hoping to expose this corruption within the system in quite an unconventional way. using cameras in a new twist in the world of reality show drama. here's my "nitline" coanchor juju chang. >> reporter: barbara and zach are going to jail.l. >> i have no idea what to expect.. >> reporter: this is day one of their lockup in a place known for violence and illicit activity. >> it's really hitting me how real this is. >> reporter: every inmateays they're innocent but zach and barbara really a. >> i hive never been in jail. >> reporter: barbara is a military wife and stayy at home mom. >> why is jail not so bad that they're not afraid to changee their ways and go back again? >> reporter: zach is a former mane who served in afghanistan, who wants to be a dea ent. >> seeking a career in law enforcement, i felt this would

other law enforcement officer has ever had. >> reporter: they are two of the seven volunteers going undercover to expose what really happens behind bars, all for the new a&e show "60 days in." innocent people serving time for fake crimes with fak identities. but with very real consequences. >> it's miserable. that's the only w wd i can tnk of to describe it. this place is completely miserable. >> reporter: this as jails and prisons across the country have been in the headlines for corruption and violence. just last week, this inmate fight in the santa clara county jail was caught on camera. just one day after the sheriff installed cameras on her own dime. >> it looked like two people, one hit him with the shoulder, en the fight was on. then a lot of other people jumped into the fight. >> reporter: crime and misconduct at the hands of prison staff is on the rise too. increasing 90% in 10 years. just last month, the fbi

in georgia for smuggling contraband and drug trafficking. they have yet to enter pleas. in 2014, sheriff jamie noel took over a jail in clark county, indiana, that was riddled with corruption and violence. >> you think you run this place -- inmates run the jail. i had parents blowing my phone up, e-mailing me, saying i'm sorry my son got arrested but he's getting more drugs in jail than he could get on the street. >> repter: so he decided to team up with a&e and hundreds of their reality show cameras to uncover it all. did you worry you're putting your career on the line by puttttg innocent lives at risk? >> i did. there's a lot of slipless nights will be i'll be honest, what we learned far outweighed me, my personal reputation. >> this was the perfect jail to do something like this at. it had had interruption corruption, it had had problems. it was known for being a violent, sort of terrible place. and this new sheriff comes in

how to fix it. >> welcome to "60 days in: the aftermath." >> reporter: dan abrams hosts the reunion show. there why safety rings. if i'd been the sheriff i would have been nervous. cameras everywhere, in theory monitoring as much as possible. but you can't have a camera literally everywhere. they had cameras all over. >> reporter: no one on the inside, neither guards nor inmates, know that zach, barbara, and the five oths are actually reality show participanqs. >> very much who's going to be the alpha male, who's going to let people run ove them. >> reporter: only sheriff noel and his chief deputy know the truth. they go in armed with nothing but surveillance cameras, a safe word, a cover story. >> we spent a lot of time making sure she knew what their cover story was, what their coverer name was. >> reporter: first they all go to jail boot camp to learn how deal with the unwritten rules of life on the inside. >> got to be very careful what was you say and how you say it. >> reporter: hoping what they learn will help keep them safe. >> don't become ngaged in

>> reporter: when they'll have to fend for themselves in a population that includes volatile, sometimes violent criminals. >> it's loud. it's dangerous. it's confusinin you have no control over anything you do. you have n privacy. >> reporter: the training does little to prepare babbara for the harsh reality. >> i've been in jail two days and it feels like i have been here two months. >> reporter: with his military experience, zach is able to adjust. >> the nice thing about being in jail as opposed to being in afghanistan is i afghanistan, you don't know who the good guys are and the bad guys are. in jail, you kind of just have to treat everybody like a bad guy. >> reporter: he's sent to c-pod, otherwise known as the most drug-ridden part of the jail. zach learns the early warning signs that a fight's about to break out when a prisoner starts casually putting on his shoes. >> called lacing up. they're going to put their shoes on to fight. >> i didn't see any of it because i stayed on my bunk. >> did you ever try to

>> yeah, that was one of the toughest situations for me. i had t# keep myself in check. i cannot get involved in this situation, i don't want to jeopardize the program. >> didn't want to blow your cover? >> didn't want to blow my cover. >> reporter: after this fight none of the inmates are willing to cooperate. >> people don't snitch. snitches get stitches. >> it's this no snitching culture that convinced the sheriff to open his quail up to reality show cameras. >> the tough part is inmates don't like to talk to me, sheriff the special. the corrections officers either, they immediately get branded as a snitch. >> reporter: but they will talk to the fake inmates who are reporting back on the intricate system of gettingng around the authorities. >> they like to make their drugs in jail. they basically take their drugs that they're supposed to be taking during the medication time, ey combine their medications together, they'll roll it up in tampon papers and smoke it. or they will melt down jol ranchers and mix it with jolly ranchers and suck on it.

are locked up because of drug offenses. >> if you keep housing bodies, treatingnghem like an animals, that's what you get in return. >> r rorter: these cameras are helping get drugs out of the jail. >> they were jikking drugs in, in their body cavities, several arrests base pod what we learned after that. >> reporter: all that surveillan doesn't necessarily mean a jail is safe. one of the show's characters is punched in the face. all caught on camera. but nothing can be done to stop it. >> i don't feel safe at all. not one second, don't feel safe. >> reporter: zach, barbara, and the other participants were compensated for the time they spent in jail. and yet not all of them me it through the 60 days. zach and barbara both managed to gut it out. >> the sleeping conditions are extremely difficult. you get a mat and you're on a metal bunk. everything's very dirty. it's extremely cold in there. the first few weeks were absolutely miserable. >> the fantasy is that it's a

state and good taxpayers are paying for you to do nothing all day. the reality is people are poor, they have mental health issues, substance abuse issues, a`d jail is a very unpleasant place to be. >> reporter: it may be reality show but the sheriff says he's implemented real changes. did yofire any corrections officers after this? >> we did. we made some arrests. we had several that actually quit. >> they y ew the writing was on the wall? >> exactly. >> you cleaned house after this? >> it was tough. it's not easy. >> reporter: barbara says she's cleaned house too. >> i came home a better person. i know that. i am so grateful for life. i have thisp new like awesome vision for myself and for my family. >> in what way do you think it changed your life? >> i don't judge. i'm so open to everyone now. i'm kind. i'm not as opinionated as i ed to be. i'm all here. next, donald trump's

why a jamaican model is saying his company misled her and the federal government. and now it's your voice, your vote. tonight the democratic presidential contenders debated in miami. univision's jorge ramos waste nothing time bluntly asking clinton about her ie-mail controversy. >> if you get indicted will you drop out? >> oh my goodnessss that's not going to happen, i'm not answering that question. i'm not a natural politician in case you haven't noticed, like my husband or president obama. so i have a view that i just have to do the best i can. >> both speaking out against republican front-runner donald trump. >> i think the american people are never going to elect a president who insults mexicans, who insults muslims, who insults women, who insults african-americans. >> i was the first one to call him out.
