Allright, MOST terrorists attacking the US are of Arab origin. And as far as I recall nearly all were muslim.
If 905 of potential terrorists come from a specific race/religion then it stands to reasn that by focusing most of your search on that specific group you will have higher chanced of finding them then if you focus equalyl on all.
And the London bombers were clean on the intelligence services radar, even including the one who had been previously examined by MI5. So even if you focus on, say, Muslims (as MI5 would have been in examining this guy), it doesn't mean you'll find a terrorist if one exists. The known bombers were not known radicals, some had families, one was a special needs teacher IIRC. Even given their ethnicity (in the case of those of Arab descent), there is no demographic differenc between them and Joe Ordinary.
More likely you'll blind yourself to alternatives. I mean, how the hell are you defining 'potential terrorists' if not by racial/religious stereotyping?
Anyone is a potential terrorist; is this a 'war on terror' or a 'war on Muslims'? Because there's a strong implication that comes from how you handle it.
How would it work, anyways, to stop Mr X (assuming he is Arab, which is a big assumption in itself) planting a car bomb? Would you subject every Arab (origin) person to surveillance to see if they bought a car or fertiliser? Would the purchases of arab-sounding names be singled out for collection by the FBI?
