Still did not answer my question, but the correct answer was provide for you in the post above yours.
Higher levels of stress and fear is normal at an airport. Most people do not fly very often so the stress of not finding their way to the right place, worry that the TSA may find contraband that you did not know was contraband, general excitement or dread about the trip, fear of flying or crowds, not knowing where the bathroom is, can all contribute to "tells".
Has any BDO caught a "terrorist" that was planning to do something to the aircraft they were attempting to board? The Jamaican does not count as he was planning on killing someone when he got to Jamaica, not do harm to the plane.
There are too many false positives in your work to be a science.
I will grant you this, the fear of failure (being caught and punished) will make amateur bad guys "sweat". Pros do not exhibit that behavior. So yes training will suppress the "tells".
