Which is exactly, of course, why we get such overreaction. Like referees, those in charge of security are only noticed when they do a poor job. Except, unlike referees, there is absolutely no penalty for false positives. They will always err on the side of safety, no matter how remote the probability of harm, because they can never punished for the unseen. Even when they get it wrong, even when what they initially thought might be a threat turned out to be no threat at all, there is no incentive to admit fault. So this aggressive attitude amplifies, until at some point, it deafens.
