For about a year after 9/11, I was pulled aside for extra special attention at the airport EVERY time I flew. The profile must have been men traveling alone.
Me, Profiled? Don't rightly know. But if any one ever starts profiling old, short, fat, bald hedaded, absent minded men then I'm in BIG trouble.
But if you stop and think about it you might realize that EVERYONE profiles in one way or another. Another way to express social profiling would be forming and opinion.
