I would hope this study would be enough to convince TSA to abandon the BDO program.

I have always questioned if anyone could be trained in Behavior Detection well enough to put in place the practice in just a couple of weeks, especially on people who the TSA employee has never had any interaction with. Given that the Behavior Detection isn't a proven science I really question is some quickly trained people could even grasp the most basic concepts of the program. And who would start answering questions from a stranger in an airport?

If TSA wants to ask me a question they had better be identifying exactly who they are and why the questions.

Looks like I had cause for my concern.
