Racial profiling actually does very little to catch the actual 'bad guys'. I just did a paper on Racial Profiling for a Criminal Investigations class and have learned quite a bit. Racial Profiling, while most associate this against black people, has since 9/11 greatly included people of Arab descent. The most ridiculous case I found was of an 8 year old boy in Oklahoma, who is of Arab descent, being routinely stopped at the airport for questioning (away from his parents). Apparantly his Cub Scout pinewood derby racecar was considered suspect in his carry-on, because it was disassembled in Tulsa.

This kind of stuff just serves to piss off the moderate Muslim citizens, who are the best weapon we have in calming or locating the extremists.
