The impression I get from your previous post is that you feel you are always right and your word is law, and anyone disagreeing with you about anything at all is not just wrong, they're lying.
Now, I at least partially agree with your previous comments about being a Thug for detaining a person for asking what you were looking for, but most of the incidents in TFA were not someone asking 'Were you looking for a bomb or something?" they were people saying "hey, there's a bomb in my bag", something completely different. And yes, I looked through them. Ony 3 out of the 30 seemed to have worded the question 'what if there was a bomb' or 'there could have been a bomb'. The remaining 30 examples in TFA were all someone claiming to have a bomb, gun, or similiar item, or to be a terrorist, or to have knowledge of someone else's bomb on the plane. NONE of these qualify for your What are you looking for, a Bomb or something example. In all of those 30 situations, even if you have already searched, the person who said that just confessed to having contraband that you missed, and more complete search is called for . This is undeniable. For all you know, when they later claim 'it was a joke' they could be trying to cover up an inadvertant slip of the tounge.
Sure, Zero Tolerance Policies like this don't leave any room for the agent to intrepret what the person meant. That is kind of the point of a Zero Tolerance Policy. There is no risk of a judgement call being the wrong decision.
