The guilty flee where none pursue

‘Pre-crime’ detector shows promise – Short Sharp Science – New Scientist

At an equestrian centre in Maryland, 140 paid volunteers walked through a pair of trailers kitted out with a battery of FAST sensors, including cameras, infrared heat sensors and an eyesafe laser radar, called a Bio-Lidar, that measures pulse and breathing rate from a distance.

Some subjects were told to act shifty, be evasive, deceptive and hostile. And many were detected. “We’re still very early on in this research, but it is looking very promising,” says DHS science spokesman John Verrico. “We are running at about 78% accuracy on mal-intent detection, and 80% on deception.”

So this will catch amateur criminals, and people who are nervous that they’ve unwittingly done something wrong while living in a police state. The professionals, who aren’t particularly nervous or evasive, will just breeze right through.
