There are about a billion Moslems around the world from every racial group. While all of those 19 men involved in the Sept 11th attacks fit a certain profile...

Taliban Johnny is white.
Richard "Shoes" Ried is white.
The guy they announced last week is Puerto Rician.

Don't forget those Filipino guys who kidnapped the American missionaries. They're also Moslem extremists - or petty crooks pretending to be Moslem extremists. It's hard to tell.

The simple fact is that while profiling people obviously from the Middle East may catch some people, doing that to the detriment of screening everyone will allow others to slip through. The terrorists are smart enough to realize that we're looking at Middle Eastern men harder, so the next one they send could well be an Asian, perhaps even a woman. Profiling based on race just won't work.
