I think researchers have said that terror organizations prefer to recruit people who are focused, calm, sane, and intelligent. I doubt BDOs are looking for that.
According to
BBC News:
"...All of the Al-Qaeda members studied came from middle or upper class backgrounds.
Two-thirds were college educated, a tenth had a postgraduate degree and more than seven out of 10 were married with children."
That sounds like a large part of the flying population. Plus, I am sure a highly educated terrorist is well aware of BDO techniques and how to counter them (if the techniques are effective at all). I would say that a highly educated terrorist probably already has an answer to
every TSA tactic and an assessment of the risks presented by each.
