 New technology can detect deception in the blink of an eye. I swear, I wasn't speeding, officer. An eye-opening look at a new crime fighting tool. So, anyone committed any crimes lately? Does anyone think they have what it takes to pass a lie detector test? I got it, guys. No problem whatsoever. Your mouth may say, no problem. But quite honestly, your eyes tell a different story. The eyes, chico. They never lie. Just ask this lie detection guy and his new tech that can see right through the lies. It enables you to detect if someone is being deceptive by monitoring changes in their eyes. Changes such as an increase in pupil diameter, a change in your blink rate. Basically, the thing uses the way your eyes move to see if you're lying or not. But sorry, bro. We need to see this thing in action to believe it. I'm Joe Nathan Glenn and I'm about to be the lie detector test. We'll see about that, won't we? Joe Nathan Glenn, if that indeed is your real name. We ask Glenn to write down a number between two and nine, which we will show to you so you know it's real. He was asked to be honest about everything, except when a question was asked about his number and to make things just a little bit more interesting. If the system is unsuccessful by getting your number, then we give you $50. Great. Now we want Glenn to beat the contraption even more. The moment of truth. I believe Nathan, he chose the number seven. Is that accurate? And there it is. He's got it accurate. Number one was seven. It worked. Now, eye lie detection is the 86% accurate. For now, it's only being used on law enforcement to test new applicants and parolees. But we find you just can't hide behind those lying eyes.
