If you want to see what happens with the lack of profiling, run the gaunlet through DTW. America's largest Arab population has the TSA setting the screening devices off at the most sensitive level. I take off my insulin pump (makes it through every international and domestic scan but DTW), my belt (only place I have to do that) and even gum wrapper foil in my pockets.
Yet last week, I picked up a dime in our office and dropped it into my pocket. I don't carry any change in my pockets, so never thought about taking it out after nearly stripping for the DTW TSA. Still.......BEEEEEEP! Full search, barely short of rubber gloved treatment.
I want to register my retina and finger prints along with all of my personal info and get through without this kind of bother.
I know, the "black helicopter" crowd will respond with why we need to be ready to overthrow the US Government (Hell I HATE TSA Peeps, but I'll do anything to get around their low IQ people!) If you're in this group,

Good thing I'm American/Dutch and look it. With a bit more of a tan I think the rubber gloved treatment would have been mandatory from the local TSA Czar.
