I'm not suggesting I have the answer to that question either. What I am suggesting is that such behavior on the part of screeners has logical consequences. Those include providing an incentive for people to utilize other modes of transport. I can hardly fault them for that, as some on this thread seem wont to do.
But suggesting that the airlines deserve to go under for attempting to find weapons borne by passengers, and that the country should want to live without air travel as a way of life and as a loss to the economy, is silly as a goal and as a security decision. It isn't as bad as they say, and the exaggerations of the easily over-hassled shouldn't go unanswered by a dose of perspective.
