TSA to investigate body scan resister

This might be the best thing they could have done to further the cause of their own demise.

How can he be charged with leaving the security area "without permission", when TSA had him escorted out of the security area?

Good! This is an excellent thing to have happen. Worst case, the guy gets fined $11k and the internet steps up to cover it, and the TSA looks even more like utter goons than they do now. Best case, this blows the lid off of the insane procedures in place and starts a snowball to help get this thing changed.

I believe "oppression under color of law" is the correct term if the TSA supervisor was not correct about him giving up rights by buying a ticket. That claim doesn't hold for a store saying "we reserve the right to search your bag on exit" and I don't believe it holds for air travel either.

Denying boarding is one thing. Just as a store can kick you out if you refuse to check you bag at a bag check. But the bill of rights is pretty clear about when you can search someone and deciding you don't want to fly doesn't exactly give probable cause for anything.

So innocent until proven huilty has now become guilty, proved innocent, but found guilty anyway.

Given the buzz around this incident, this could well backlash on the TSA.
