Technology and big brother equipment, for better or worse, have taken us to the next possible step in TSA screening. A passenger’s rapid heart rate and heavy breathing sets off an alarm. A machine senses his skin temperature fluctuation, and TSA crews move in to question him and further the investigation. Is he a terrorist? Or is he simply a passenger nervous about flying?

The Feds have high hopes that this high tech big brother technology will pay off big. The biometric equipment is ow being tested and implemented by the TSA, in airports all over the US. Critics state that such types of screenings may be undependable and misinterpreted.

Proponents of the new equipment claim it is fast and portable, measuring vital signs similarly as a polygraph would, with a single major difference. It doesn’t require wires to be physically connected to the person of interest. That makes scanning covert and quick as the subject merely needs to walk by a set of cameras.

The TSA now has trained over 2000 of its technicians to use these devices, and interview those who are deemed as “risky.” The new devices are designed to measure people during normal activity, and then flag suspicious ones. Those flagged with be further interviewed directly in front of the cameras that can detect the tiniest facial movements to determine if they are trying to hide something.
