The sad reality is that we've more or less given our government emergency powers to issue such ludicrous directives to the airlines and for what? Some semblance of security? I guess Ma and Pa Kettle feel more safe on the airlines on their one round-trip flight they take every two years to see the grand kiddies but for those of us who fly more than that, it's a pain in ass and we're smart enough to realize where the holes are in security. I've heard plenty of instances of people bringing things that they didn't expect they could through security by mistake.
Our representatives in government aren't going to revoke these powers any time soon unless we ask them to.
