To Profile or Not to Profile?

Many people say that we should profile at airport security because the majority of people looking to attack America are Middle Eastern and men.  Therefore, white blond women should not be searched at airports. 

I understand the argument, though I didn't agree with it, until recently when I read this New York Times article about Colleen LaRose, a white blond woman from the suburbs of Philadelphia.  She calls herself JihadJane online and she has not only contributed money to terrorist groups, but "expressed a desire to become a martyr for an Islamist cause."  This, according to the New York Times, is part of a trend of Al Qaeda finding whites who will blend into society and join their cause.

To me, this is not only a little frightening (I'll admit, my internal racism was a little comforting), but it also proves just how global (or local) our enemy is.  No longer can we cower in racism, we have to realize, and your granny will have to deal with the consequences that anyone, regardless of race could be an enemy.  Colleen doesn't look very 'foreign' (and therefore frightening) in the top picture, but if she were dressed like she is to the left, would it become justifiable to strip search her in an airport?  Does her turban make her a threat or is it the ideas stored within?
