The real problem with racial profiling is although it makes it more likely that you will catch the offender who fits the stereotype, it makes it less likely that you will catch the offender who doesn't.
Terrorists are not stupid. If we adopted the knee-jerk racial profiling that people seem to be calling for, all we are doing is sending the message "Select someone who doesn't fit the stereotype to be the bomber, and we'll let him on the plane"
