You’re at an airport, standing in line to go through security. You’re sweating, having rushed from the curb with bulky suitcases, gripping a zip- lock bag in one hand and your shoes in another. Nervous that, as the security line crawls along, you may miss your flight, you glance around impatiently at the officials and your watch. Government agents are watching your every move––looking to see whether you exhibit certain facial expressions that they believe are the telltale signs of a terrorist. This is Screening Passengers by Observation Technique (“SPOT”), the Department of Homeland Security’s behavioral profiling program, in which trained federal agents closely observe travelers’ faces for hints that they may be security risks.
