No, not discomfort. It amazes me that people complain, partially, the WBIs are a violation of privacy - but seemingly have no problems forcing a captains auidence to listen to what they want to say. Yeah, I know, it's in public, so people have no expectations of privacy (except, strangly, considering the use of the WBI), but why would a critic of TSA seem to care if they force people who can't go anywhere to have to listen to what they have to say. Make all the claims you want, planning on specifically talking about a specific topic to people you know can't leave is nothing more than an ambush.

As a similiar example, last year I was on a subway and we were all packed in there. A man waited to the very end to enter and then waited till the doors closed, and only then started to spout to everyone the evils of this or that. So much for my conversation with my friend, huh? This guy had a right to speak - we were in public - but I had no right not to listen or walk away.

Basically the same thing at the checkpoint.
