@ChrisMayLA6 Well, it certainly doesn't help tourism to read about all the crazy interrogation at the US border. Granted, this only happens to 0.00001% of all tourists, but since people are not capable to reason around probability, I imagine that this has discouraged a few million people at least from traveling to the US.

Indeed; the fear that is intended to act as a deterrent is (unfortunately for US tourism) rater unfocussed as to its effects
