In your original question you did not ask what the difference was in their BEHAVIOR you just asked what the difference was. I supplied an answer to your original question.

Not being a trained BDO I would have to make the educated guess that the behavior exhibited by a trained terrorist would have less "tells" than a drug mule. A terrorist believes that what they are doing is right even if they have to hide those actions. A drug mule knows what they are doing is wrong and therefore will exhibit more overt "tells".

I know you are proud of your training, but honestly your training is based on junk science. You can no more tell that a person is exhibiting "tells" based on nefarious "nervousness" than you can someone that is exhibiting "tells" based on other stimuli.

I would wager that I could, without training, be able to SPOT at the same rate of success or hirer than most of your BDOs.

All your training has taught you is to pull your head out and pay attention to your surroundings and to go with your gut feeling.

Sorry to sound so harsh but your (BDOs) error rate is too high to be considered a science.

Now that I have answered your clarified question please answer mine.

For what purpose do you look for a collection of behavior?
