Schneier on Security: Behavioral Assessment Profiling
Schneier on Security: Behavioral Assessment Profiling: "Behavioral Assessment Profiling

On Dec. 14, 1999, Ahmed Ressam tried to enter the United States from Canada at Port Angeles, Wash. He had a suitcase bomb in the trunk of his car. A US customs agent, Diana Dean, questioned him at the border. He was fidgeting, sweaty, and jittery. He avoided eye contact. In Dean's own words, he was acting 'hinky.' Ressam's car was eventually searched, and he was arrested.

It wasn't any one thing that tipped Dean off; it was everything encompassed in the slang term 'hinky.' But it worked. The reason there wasn't a bombing at Los Angeles International Airport around Christmas 1999 was because a trained, knowledgeable security person was paying attention."
