i'm not saying the way TSA handled this guy was appropriate once he wanted to leave (they told him he couldn't leave til he went through the scan or got patted down, wtf)...but clearly this guy came into the airport with confrontation on his mind. Why else do you turn on your cell phone before it even occurs that something could go wrong?
if you don't like TSA's security measures then make your voice heard. Boycott flying, talk to the media, write to the companies. don't go into the airport and be a douche and pretend you have the right to bypass whatever rules and procedures you chose just because you paid for a ticket
