Once again, don't fly. Unfortunately I live the threat every day and know that it is serious. And we're not talking about other ways to kill you -- we're talking about the current threat to aviation. Again, if you know a better way to stop people from smuggling explosive materials in non-metallic containers sewn into their clothing or strapped to their bodies, then please share. THAT is the current threat and it is a reality. More than likely the scans/pat downs will force the terrorists to change their methodology; if so, then they worked.
You seem to want to argue more than to discuss the need for the scanners or alternate pat downs. And "approved flyer lists" are not realistic and will never happen. Anyone calling for something like this is naive.
