I think they need to allow liquids past checkpoints like in Australia. Even without answering questions about your travel plans, in Australia you don't need to take your shoes or belt off. You can bring liquids. You can bring a whole bottle of wine or two.

Australia doesn't waste taxpayer money on Behavior detection pseudo-science. (Although I'm sure that most (American) TSA "agents" couldn't find Israel on a world map if you gave them three tries, and I seriously doubt that they went to Ben Gurion Airport for training.)

Maybe with this you will be allowed to take liquids through American security, keep your shoes on, and not worry about these patdowns unless you have a secondary chat with the behavior screening official. Or maybe the screener will just continue to make up their own rules "out of an abundance of caution" and say that at THIS airport you have to take your shoes off, surrender your liquids and get the full monty groping. Or maybe those who have hearing problems or speech problems or don't speak much English will be unable to play the BDO's little game and get the full treatment every time.

I don't mind flying in Australia where, even without answering questions, I can bring liquids on, not have to remove my belt, shoes etc and still know that no planes are falling from the skies.
