you are right and only an amateur would try and "bring something on their person" I won't go into more detail as I do not wish to help bad guys but the system is terribly broken and billions of dollars are being wasted. The whole point it to make the traveling public feel they are safe when that is far from the truth.   

We need serious people with skills to look at it and fix it so those traveling are as safe as we can get. You folks are right, Israel has it right and we do little of what they do. By the way, every flight on an Israeli aircraft has a marshal. How many of them could we pay for if we didn't piss our dollars away on a useless piece of "security" equipment that does nothing to help the cause
