People have certain right to certain privacy. Wiretaping is a very serious offense. To the best of my knowledge, one cannot be recorded unless one consents to it. I know that is how phone companies, bank, credit credit companies, and insurance companies operate; they ask for your permission before recording you.

With airport, it is pretty mess up that you loose your 4th Amendment right but loosing a 5th too is pretty bad. With the video recording, it is the gray area and they use security as a way to bypass getting your consent. However, I can't see how wiretapping is legal when video recording as well as security and law enforcement are present.

So I ask again, do they record people talking at checkpoint and while asking you questions during the pat-down. For example, if I make a nasty comment while being stuck in the x-ray machine, which radiate harmful ray at me, I don't want that statement to be used against me in the future. I could be saying that if someone owes up to the truth that these machines are harmful, I will suit them to the poor house and hope they all rot in jail. That is a private conversation and I am entitled to it. If I want it recorded, I'll make my own copy and release it.
