So maybe it's not really to the point of the TSA yet, but watch out for anyone with a camcorder. Bet you didn't know it's possible to see through certain clothes with a simple camcorder (with night vision technology) and exposed film. So the next time you're part of a company get together and someone has a camcorder -smile big.
Lots of youtube clips on it. Probably nothing to really worry about, but it gets one thinking.
