Ok, let me tell you how it's going to be. When you innocently walk up to me and try to engage me in your little profiling game, I'm gonna tell you where to go and what to do with your self and various orifices when you get there.
How dare you invade yet more of my space, usurp yet more of my freedom, and try to pigeon hole me into your idea of what someone with nothing to hide does with their "macro facial expressions"
What ever happened to innocent until PROVEN guilty"? Oh yeah, the patriot act is what happened.

"They who would give up an essential liberty for temporary security, deserve neither liberty or security"--- Benjamin Franklin

seriously, we are going into a long dark night, praying for protection at the alter of Government....we are going to get exactly what we deserve.
