david was proud to be an american soldier. and i know i'm prejudiced because he was my son, but i don't think he had a mean bone in his body. there is not a day that i don't think about david. when i saw donald trump attack another gold star mother, i felt such a sense of outrage. "she was standing there, she had nothing to say..." if donald trump cannot respect a gold star family, then why would anyone in america think he would respect them. votevets is responsible for the content of this advertising. good evening and thanks for joining us.

tonight, innocent people posing as prisoners risking their safety and sanity to shine a light on alleged corruption and violence. how one sheriff is using their stories to clean up the system. here's "nightline" anchor juju chang. >> so this is where i lived. >> reporter: this is where ashley spent two months locked up. >> my heart is racing. i'm nervous. for sure. >> reporter: indiana's clark county jail. >> the first night. i don't feel like i ever really slept soundly while i was here. >> reporter: enduring fear, deprivat deprivation, and shocking proposals from other inmates. >> they offered me clothes right away which i was like, oh, that's really nice, how great. they wanted to see me change. there are many times i was offered to join in with someone who was, you know. having sex. >> you were sexually harassed? >> yeah, absolutely.

choice. you see, ashley is not a criminal. she left her husband and new baby at home. >> clean out his ears. >> reporter: to go behind bars for a&e's show "60 days in." where innocent people serve real time for fake crimes. fending for themselves in a population that includes volatile, sometimes violent criminals. all to help expose what really notorious county jails. this is sheriff jamie knowles' jail. >> these are the temporary holding cells. >> reporter: when he took over in 2014, knowles says it was riddled with corruption and violence. >> stuff was getting smoked under the trees. >> reporter: drugs were rampant inside. he was determined to stop it. >> this is intake? >> all the doors that you see

serious offenders. >> reporter: he took a drastic step, opening up his jail to the prying eyes of a&e's cameras. >> tell me about the naysayers, how many said sheriff, you're crazy if. >> i had a few people tell me that and i thought about it myself in the very beginning. i'm going to take the good with the bad. there's a lot of bad inmate behavior and officer behavior. still today i'm ultimately responsible for that. >> reporter: crime and misconduct at the hands of prison staff is on the rise as well. increasing 90% in 10 years. in his deck of cards. >> reporter: sheriff knowles says a&e's new high-powered cameras which he gets to keep helped pinpoint his jail's vulnerabilities, from drug dealing to allegedly corrupt guards. and he is cleaning house. >> how many guards did you fire? >> between the two seasons, i think 15 total that left, resigned. >> that's like a third of your staff, your guards. >> that wasn't easy but the bottom line is i told them

illegal activity, i'm going to personally arrest myself and walk you to jail. >> reporter: participant on this the show feed information they learn on the inside -- >> drugs. >> raw sewage. >> they treat us like animals in here. >> reporter: back to the sheriff and his deputies. >> i'm in a pod with so many [ bleep ] drugs. >> reporter: the intelligence the sheriff gathers from participants like ashley is invaluable. >> the point of you guys being in jail, volunteering to be in jail, is to be the sheriff's eyes and ears inside these pods. what did you repor >> there were definitely guards that crossed a line. then there were guards that were amazing. who, you know, helped me through my time here. >> reporter: in the past, ashley struggles with alcohol and drug addiction. >> my alcoholism became life or death. i ended up overdosing on alcohol and cocaine. >> reporter: she's volunteering to give up her freedom in part, she says, to help others.

her life could have been. >> i was in such a vulnerable place. being here, being away from any sort of comfort that i had, being away from my family, my son -- just, i was very emotional. >> reporter: she's been sober four years. but jail will be the ultimate test. >> how are you feeling? >> not ready to leave yet. >> i threw myself back into a fire that i had worked so hard to pull myself out of. >> reporter: ashley thought she knew what to expect on the inside. her husband zach took part season one. >> everybody uses the same toilet? >> uh-huh, it's a metal toilet, there's no lid, you're sitting on the metal. >> seriously? >> reporter: like zach she was compensated for her time behind bars but nothing prepared her for her first night in. >> it's cold. it's concrete. it smells bad. people don't shower. >> it's an assault to the senses? >> it's a rough place to be. >> how many times during the process did you think, i'm not going to make it?

where i felt like i had reached my breaking point. and that i needed to be done. i needed to go home. to be with my baby. >> reporter: and even though zach encouraged her to do the show -- >> you sound like you don't have anything else to talk about so i'll let you go. >> reporter: it's a big strain on their marriage. >> this has not been an easy process i think for either one of us. i'm used to him being in the military and leaving and going on a mission. the roles were reversed for the first time ever. >> reporter: breaking point. >> i'm fighting left and right and my husband's out drinking. >> to him this is like a cakewalk. he doesn't have much empathy for me. >> reporter: it is real-life drama like this -- >> [ bleep ] -- >> reporter: that's made "60 days in" a smash hit for a&e. abc news chief legal analyst dan abrahams -- >> welcome to "60 days in: the aftermath."

compelling is that real, authentic people are going to a real, authentic jail. where real, horrible things can happen. >> there are always skeptics who see the show and say, this can't be real. >> this is not a reality show. this is reality. >> were you surprised that basically it became a hit show? >> to me it never was about that. it was, how many more people can we touch, what can we learn? >> reporter: thanks in part to the show the sheriff tells us there is now better training for prison guards and more programs for the real prisoners behind these bars. >> i just recently came back. >> when you say things are running smoother what do you think? >> it's not too much about this guard's doing this, this guard's favoring this, whatever else. everybody seems to be getting the same treatment. >> reporter: it's not just the jail benefiting. ashley says she's taking away a few life lessons as well.

even though they're criminals you've got to marvel at their ingenuity. you're about to see the extraordinary lengths identity

here's abc's nick watt with another look at how to protect your money. >> reporter: a gas station, miami beach, florida. watch the chatty guy in the tight aquamarine polo. he points. the clerk, distracted. while she's gone, watch his alleged accomplice. in mere seconds he slips an identical cover over the store's card reader, a device police believe will automatically steal your card details when you think you're just making a purchase. you'll have been skimmed. robert siciliano is a cyber crime expert. >> when it comes to stealing credit card information it's as easy as swiping a card in any skimming device. >> reporter: a hidden camera inside a gas pump in arizona. those things, an alleged thief apparently searching for the skimmers he earlier placed on the pump to harvest card info. >> he put those in there, for whatever reason they're not

because i have them. >> reporter: sean marquez installed a night vision spy camera instead. >> we may have the first-ever video of organized bad guys actually trying to retrieve their skimmers. >> reporter: credit card fraud is a $16 billion a year problem in the u.s. alone. skimmers every day, every hour, stealing your digits. >> they can use those 16 digits over the phone to place a phone order. they can use them online to plug i they can actually clone a card, they can burn the information onto a blank atm or credit card and use that out in the wild. >> reporter: still not afraid? listen to this reformed credit card thief. >> it's very easy. and it's a lot of money. so anything i wanted i would go out and get for free using these cards. >> reporter: dan, poaching turned gamekeeper. >> somebody turned my partner in and he turned me in. >> reporter: then he started

skimmers helping themselves to the data on our magnetic strips. >> when the magnetic stripe was created, identity theft wasn't an issue so the data was never properly encrypted. >> reporter: now this is the latest weapon in the fight against credit card crime. >> this right here is the recently issued standard chip and signature card. it is supposed to eliminate the cloning of your credit cards. >> reporter: because the chip holds your data encrypted. you may have one in the mail from your bank it's the panacea, going to solve the whole problem! no, it's not. >> skimming is still alive and well. and it will continue to be alive and well as long as that magnetic stripe is still on the back of our cards. >> i'll have that cheesy tomatoey one, and water. >> reporter: still there, because it's taking a long time and a lot of money -- >> you have a chip? >> no, just a swipe. >> reporter: to make the switch.

with all my details on it. watch this mcdonald's drive-through clerk in florida, swipes once through the skimmer, once through the register, so fast you've no idea. cops say the clerk was stealing digits from up to 70 cards every shift. >> they actually were able to catch the individual sliding the card and grabbing the receipt and hand it to me all in one nice movement. you'd never know that he was doing anything wrong. he seemed to always be smiling. he was getting more than minimum wage. >> reporter: the clerk pled guilty, got two years' probation. or there's this. i'm about to steal this coffee drinker's credit card details with an app on my phone, surreptitiously placed on her wallet for just a few seconds. so to stop that happening to you, buy what's called a shielded wallet. like this. a wallet that blocks scanning devices. or the cheaper option, cover all your credit cards in aluminum

kool and the gang. with that magnetic strip still in place the atm also a potential danger. >> be aware that at any given point in time there could be a skimming device on the face of that atm. >> reporter: this might sound stupid but check that there's nothing jiggling around that looks like it's been attached onto the front of the atm. sao paolo, brazil. looks like a normal atm? think again. watch this cop pull off the false front your credit card details when you think you're just withdrawing. >> make sure you cover up the actual keypad with your other hand as you punch in your pin code, there could be a camera anywhere recording your pin number. >> reporter: robert siciliano has an atm in his garage. >> when criminals set up a skim scam there's generally two parts to the scam. one would be a small wireless camera here. hidden behind this mirror.

keypad as you punch in your pin code. in addition to the camera, of course, is the skimming device. the skimming device fits on the days of the atm so when you swipe your card through, it grabs the information off the back of the magnetic strip. even if a consumer has a chip card, it doesn't make a difference because all atms in the u.s. still use the magnetic stripe. >> reporter: as chips on cards catch on, thieves will move increasingly to so-called card not present transactions whe the chip means nothing, like online shopping. sweet, pro-flex clothes dryer transition duct, $10.98. tap in the dic giants -- >> nick, stop. whenever you use free public wi-fi, know somebody within 500 feet can always think of your data. the problem with free wi-fi is it's unencrypted and unprotected. have a vpn, a virtual private network that encrypts and locks down your information on free wi-fi.

on as your password. get complex, it helps. >> have strong and long passw passwords and have a different password for every account and consider a password manager. >> reporter: and check your statements. it's the only way you'll know you've been skimmed. >> some studies show that as many as 9 of 10 consumers don't actually pay attention to their credit card statements. >> reporter: even sign up for alerts that ping you every time your card is banks and businesses are now spending billions to change to the chip. but will they be able to stay one step ahead of the skimmers? >> researchers in a controlled environment have been able to get information off of chip cards. whereas out in the wild, criminal hackers haven't actually been able to crack the code, as far as we know. >> reporter: as far as we know. are you reassured by that? oh, and miami beach detectives

skimmer over the gas station card reader, detectives say they are still at large. i'm nick watt for "nightline" in los angeles. up next, how a wine once considered the bottom of the barrel is now being called the coolest drink of summer. i'm mary ellen, and i quit smoking with chantix. i have smoked for 30 years and by taking chantix, and that was amazing. along with support, chantix (varenicline) is proven to help people quit smoking. it absolutely reduced my urge to smoke. some people had changes in behavior, thinking or mood, hostility, agitation, depressed mood and suicidal thoughts or actions while taking or after stopping chantix. some had seizures while taking chantix. if you have any of these, stop chantix and call your doctor right away. tell your doctor about any history of mental health problems, which could get worse or of seizures.

if you have these, stop chantix and call your doctor right away as some can be life-threatening. tell your doctor if you have heart or blood vessel problems, or develop new or worse symptoms. get medical help right away if you have symptoms of a heart attack or stroke. decrease alcohol use while taking chantix. use caution when driving or operating machinery. most common side-affect is nausea. i can't believe i did it. i quit smoking. ask your doctor if chantix is right for you. covering is caring. because covering heals faster. to seal out water, dirt and germs, cover with a water block clear bandage from band-aid brand. incredible bladder protection in a pad this thin, i didn't... ...think it would work, but it does. it's called always discreet for bladder leaks, the super... ...absorbent core turns liquid to gel. i know i'm wearing it but no one else will.

there was a time, not too long ago in fact, when rose wine was considered gauche, and other faintly derogatory french words. but that's now changing big-time. it's more than a drink. it's a lifestyle. rose, once considered the red-headed stepchild of wine, is having its moment in the sun. people can't seem to get enough. >> national rose day! >> reporter: now josh astrovsky, the fat jewish, is using social media to launch his own wine,

his line and many others capitalizing on a booming market. rose sales up 35% since last year. >> it's not about us, it's about rose. >> reporter: today we're cruising around new york city in a pink convertible as part of his parade for national rose day. >> it's about delicious. how many other things have parades? rose's delicious and deserves a parade. >> reporter: a big part of the rose market, millennials using social media and instagram hash tags even cruises dedicated to the pink drink. on the boat one of the largest rose festivals. 1,000 guests and more than 150 different rose varieties. and back on solid ground, he's convinced rose is here to stay. >> a lot of alcoholic beverages have gone out of style. do you worry what happens when rose isn't in vogue anymore?
