All the personal belongings going thru x-ray can also be modded to record pretty good quality video/audio.
Ask a gadget geek about "Surveillance Camera, High Resolution DVR, Photo, Video and Voice recording, 4gb Memory and Webcam Function
Watches!"
Hammacher Schlemmer used to sell (still do?) cool video recording sunglasses. With some
minor mods, they can be turned into regular glasses.
A dedicated outdoors person I know, has these: "Mossy Oak Break Up Camo Video Recording Glasses"--he has shown me stunningly clear video of the "great" outdoors.

A final note: If you are required ("requested" in TSA Speak) to remove all your personal effects to put through the carry-on baggage X-Ray, it's going to be harder to retain a electronic device for purposes of recording. Perhaps the reason for TSA having passengers remove all items except for clothing and underwear is to eliminate the possibility of having the encounter recorded.
If you have traveling with a partner, assuming they do not require both members of your party go through sequentially, you have the option of trading the recording position.
