New Scientist reports that the Department of Homeland Security recently tested something called Future Attribute Screening Technologies (FAST) — a battery of sensors that determine whether someone is a security threat from a distance.

Sensors look at facial expressions, body heat and can measure pulse and breathing rate from a distance.

In trials using 140 volunteers those told to act suspicious were detected with "about 78% accuracy on mal-intent detection, and 80% on deception", says a DHS spokesman.

Does this sound like Minority Report movie?
