A threat to one right is by it's own admission, a threat to them all.

People would likely describe me as an unabashed Neo Conservative, however, that being said Jefferson will always ring loudly in my ears.

The problem is not the inefficiency of one search method over another. It is the wholesale description of an entire population as a physical threat to your well being.

Like saying all black people would rob,loot and steal if given the chance. Or all Irishmen will get wildly drunk and beat on each other if you give them a room full of whiskey. Or all Italians are members of the Mafia. It's ludicrous and has very little to do with being politically correct.

That being said, do you think it would be natural for a student traveling from Dubai to have a bit more scrutiny than say an albino from Norway?

Absolutely, but I wouldn't attribute that to a racial basis.
