Prohibited or against the law?
My very basic understanding is that you can take pictures
as much as you want of or inside of airports. Still, you are not allowed to take pictures in immigration or customs, so it does not seem out of the realm of possibility that the TSA would try to extend that same coverage to their facilities.
