Racial profiling is not a good idea. And my reasoning behind this is NOT that it's wrong or right. Here's how I see it: as soon as you start looking more suspiciously toward one group than another, then you're paying less attention to everybody else... and that's a hole that's easily taken advantage of.
I think we ought to be equally suspicious of ANYBODY who's acting oddly. It's a matter of being aware of what's going on, not of profiling anybody.

Great idea, Tom... I tend to use either the 5 button or the 0 button myself. I think a thumbs up/down system would be much better.
