Is profiling such a bad thing??

In a recent discussion on my car forum, we've been dissecting the nuances of profiling Islamic extremists. While on paper this may seem like a logical route to ensure domestic safety, it is far from simple. Granted, we do have a profile for the 60+ terrorist acts against the U.S. and its citizens: militant Islamic extremist ages 17-41. No gender, no national origin, and no physical attributes define this large group. It has been said that profiling Muslims in America is akin to the Japanese internment camps of WWII. But, when was the last time Granny Mae and Uncle Wilber strapped a pack of ball-bearings and C4 to their coveralls, in order to create a painting similar to a Jackson Pollock work...only using their innards as the paint and a café as the canvas??
