I don't mean to rain on the parade, but these kind of comments have been around for awhile. The only difference, as the OP said, is that the TV station didn't edit out the comments.
All that said, the mannerisms in which the passengers said them were mild. No one was really peed off, which would have made for better TV.
I don't share the sentiment that The Empire is starting to crumble or anything. The TSA already knows people question their presence and ability, hence all the PR tactics both at the "security" checkpoints, on their website and with their press releases.
