As to whether the TSA uses them, I don't know. You'd have a difficult time with the privacy argument since there is little or no expectation of privacy at the checkpoint.
I agree, except that the camera views the TSA releases are always overhead surveillance cameras. The TSA has nothing to gain by being too good with video and audio checkpoint surveillance.
