Washington (CNN) -- Don't like the way airport screeners are doing their job? You might not want to complain too much while standing in line.
Arrogant complaining about airport security is one indicator Transportation Security Administration officers consider when looking for possible criminals and terrorists, CNN has learned exclusively. And, when combined with other behavioral indicators, it could result in a traveler facing additional scrutiny.
CNN has obtained a list of roughly 70 "behavioral indicators" that TSA behavior detection officers use to identify potentially "high risk" passengers at the nation's airports.
Many of the indicators, as characterized in open government reports, are behaviors and appearances that may be indicative of stress, fear or deception. None of them, as the TSA has long said, refer to or suggest race, religion or ethnicity.
But one addresses passengers' attitudes towards security, and how they express those attitudes.
It reads: "Very arrogant and expresses contempt against airport passenger procedures."
TSA officials declined to comment on the list of indicators, but said that no single indicator, taken by itself, is ever used to identify travelers as potentially high-risk passengers. Travelers must exhibit several indicators before behavior detection officers steer them to more thorough screening.
