Transcript for All About the Apps That Could Put Kids in Physical Danger
Want to continue our series what your kids don't want you to know. T.j. Holmes is back with us. This time with some apps parents may not know about that can present such real danger to our kids. T.j., eye opening. Yeah, the past couple of days showed what happens when family don't talk. We'll transition to stuff that's downright scary that can put your child in physical danger. There is even an app out there that on its own front page it tells you, be careful predators have been known to use it. Apps, the staple of teenage years, that keep your kids engaged and social but parents, beware. Some apps have features that authorities say could put your teens at risk. The lives of three young women in Philadelphia cut short in December, their car slammed into a tractor trailer and burst into flames. Surveillance video shows the girls spreeing by moments before the crash. The family of Gia, a passenger killed in the crash believes the filter that allows you to clock your speed on snapchat played a role in her death. One of her friends told me she was snapchatting throughout the night and the car, they were showing that their speed, how fast they were driving. Reporter: Snapchat tells ABC news it takes distracted driving seriously including a do not snap and drive warning message when the geofilter is first accessed. There is a lot of good that can come with social media but there is a lot of bad. Reporter: District attorney family Casey has been outspoken about the dangers of social media and in particular the. App kik. It made headlines when 13-year-old Nicole lovell was murdered when she met one of the suspects involved in her murder on the kik app. Kik tells ABC news, we have zero tolerance for any behavior that potentially affects the safety of our users as well as our 24/7 support team we offer blocking and reporting tools to allow users to flag unwanted content or can tact. We have children being killed across the country by people who are luring them through social media. Reporter: Omegle, another one gaining attention puts two users in an anonymous chat room and on the app's own front page a frightening warning, predators have been known to use omegle so be careful. New Mexico police investigating a case of a stranger who allegedly targeted a 13-year-old girl on the app. The mother says within minutes of her daughter using the app, she received inappropriate messages and threats. First it was very innocent. Then all of a sudden the person on the other end started becoming vulgar. The home page say the people you encounter on omegle may not behave appropriately and that they are solely responsible for their own behavior. Essentially giving your child a phone you're opening the door to the world and inviting them into your home. And parents were not trying to scare you. We're trying to inform you. But still here, guys, at the same time parent, what are they supposed to do. It's impossible. Don't even try, to keep up with your kids. They're going to be ahead of the game but it's still so important to have that open line of communication is the best you can hope for. You started that this week. Yeah, you have. We want to give you more information now. We'll talk about this with Callahan Walsh a child advocate for the national sencenter for missing & exploited children. Thanks for having me. What do you do if your kids wants to download them, yea, nay. The parents need to be on top of the technology and need to know how they work. The best way download them themself, get on there and see how the features work. Check out if there's security or five si settings and determine whether that's right for your child or not. How dangerous -- we heard about kik. We heard about omegle. How dangerous is this? It can be very dangerous. The child has no idea who they're chatting with. Territory does the parent and the fact that a lot of these apps have features where you can search for certain age and gender, these predators are using it as a private hunting preserve for kids. They can target the exact age and gender they're looking for. There are security measures but something else parents can do. Definitely, knowing the technology is great. Setting ground rules so your children have expectations of making sure there's consequences if they break those rules and ongoing conversations. There's no substitute for conversations with your kid about safety measures. I do like the idea of downloading it and learning how to use it. It's very daunting as a parent. There is like a generational gap in our knowledge. Oh, definitely and that gap may never be narrowed and the best way, again, is we say have ongoing conversations with your kid, especially the conversations you're going to have with your youngest child isn't the same one you'll have with your oldest child. When you see a warning that says predators have been known to be on this app. It puzzles me why children are on the apps at all. I know they're ahead of us but when you have a warning like that. A lot of types parents just have no kwood they're on them. I brought it up yesterday because we have been talking about it all week and I brought it up with my younger child and a typical response, yeah, I know, I know, but they don't know. Even some parents, they think, well, the device my child uses doesn't have a data plan, can't make phone calls or texts but as long as it can receive wi-fi they can still get on these social media apps, the coffee shop, the library, they can get on them. The bottom line parents need to educate themselves. Exactly. They need to know and like Lara was saying I know my parents used to say how much older they were that they didn't know how to do some thing, that's no excuse. You have to go out and do this. The platforms are trying to take steps in the right directions and creating trust and safety centers to bring in the national missing center for exploited children and help them create policy and safety tips where they then put that on a website. It's oftentimes their safety center where parents can go and look for resources to help them keep their kids safe. Didn't you say yesterday the rule handing your phones in when you go to bed. They don't like this but I think it's a great rule. Time for sleep. We bought old school alarm clocks. We need our phone. No, you really don't. Some kid I'll introduce you next week, they're up to midnight. They're on their phones constantly. Older high school kids but everybody has their different rules. A lot easier when the computer was in the living room, right? Easier for parents to monitor but now it's in their pocket, bedroom and bathroom. Great information. For the work that you do. Thanks. T.j., keep it up. Keep bringing it. This has been my guy. Step by step he's been guiding
