Security screeners look for signs of stress, fear and deception in passengers. Here's how they might identify fear and distress, depicted in illustrations used by the TSA:
Distress: The inner corners of the eyebrows move up, and the lip corners turn down.

Fear: Eyebrows are raised and pulled together. The upper eyelids are also raised, exposing the whites of the eyes. Often the lips stretch horizontally.
