Over 1500 Police Departments Use This to Question Suspects - FileCabi.net
Watch the whole video.
I found this video on the filecabi forums. Even this prank machine (HALAL, get it? lol) seems to perform better...

The pentagon has already banned its use in the military. But the police departments are still buying them.
Now, I do know that the police will not use just one piece of evidence on matters like these. And in the trial shown in the video, they used the kid's statement rathar than the machine's report. But, I dont see why they even use something that comes from a "Dr." who got his PhD from some "university." It just uses the "stress" levels recorded in the voice of the subject. Even a polygraph (lie detector), uses more variables like blood pressure, muscle stress etc. and has an accuracy of 85%. This one claims a 98%.
Lets see what you guys have to say about this.
