What Is Suspicious When Trying to be Inconspicuous? Criminal Intentions Inferred From Nonverbal Behavioral Cues.

The present study investigates whether nonverbal behavioral cues to hidden criminal intentions during the build-up phase of a criminal act can be measured. To this end, we created recordings of actors once in a search situation and once committing a mock crime (theft or bomb placing) in a public crowded area. For ecological validation, we used authentic CCTV footage of real crimes in Experiment I.
