To illustrate the point even further

Try walking away without attempting to bait someone who's job depends on assessing and searching people. Or better yet walk up to the sign that warns you of the impending search (usually placed at the entrance to the building), read it, go home. It's easy.

I've never seen any such sign before. What if someone who has never flown before, walks up and changes their mind. Has nothing to do with baiting or IQ.
