I should also point out my STRENUOUS OBJECTION to any form of computer scanning of people. This should remain a common sense decision based on intuitive factors and basic sane assumptions about who would be up to no good. I think I'd let dogs pick out the bad guys at the gate.
I'm not so much interested in who is doing what, as I am in seeing that Justice and Common Sense go hand in hand. One of my assumptions is that a just country is a secure country, because it need not be embarrased by its ideals.
