Some industries adopt psuedoscientific methodologies over time I think. Just like how hostage negotiators are taught in terms that a psychology expert may have different terms for explaining.

These are classic signs of lying. What I still really don't understand is, if my tiny lotion bottle could be an explosive or explosive material...then why does the TSA agent throw it in the garbage can next to them? One of the most vulnerable areas for attacks are the security lines. Every foreign country dealing with security in airports realizes the most dangerous part of the airport are the check in and security lines. There are so many dumb rules and terrible training that it makes airports less secure.

Next time you are at an airport, you may not want to gaze down at your feet. But also be careful not to stare at anyone...

So it'd look less suspicious if I just stand there with my eyes closed the whole time? I guess that's okay, it'll help me escape to my happy place til it's all over...
