Some TSA officials are trained in behavior detection. "They are not looking for a certain type of person. What does a terrorist look like?" Hardy asked. "They are trained in behavioral patterns -- facial glitches, mannerisms, expressions."
The behavior detection officers have been such a success that other countries have asked TSA for advice on training, Allen said.
Other countries???
