"Profiling" may be an ugly word, but why is that? People don't want to be segmented based upon characteristics? Big deal. We're looking for terrorists, not potential employees. When looking for a suspect, good detective work involves profiling. You gather clues, build a profile, and focus on that profile. In cases of terrorism aboard airliners lately that have sparked this intense level of screening, there is ONE characteristic that ALL terrorists have in common, but we're afraid to act upon that single, common denominator because someone might feel "uncomfortable." I'd rather a few people be upset for being "profiled" than to have some stranger put their hand on my preschool daughter's crotch.
