I would simply tell the clown that if someone needs to search me because they think it will somehow maintain national security, then until the Supreme Court reins your rogue agency in and re-confirms the rights of law-abiding Americans, so be it - but I will not stand in a booth to wait for it to be done. I will stand right here in plain view and you can summon me when you are ready.

Technically what they are doing is still detention IMO and this needs to be addressed, but I'll be damned if I'm gonna be corralled like a farm animal.
