Of course the fact that they were actually trying to get into Afghanistan to fight on the side of Osama bin Laden is totally beside the point, right?

And aren't you the one constantly berating the authorities for not having done something to prevent 9-11?

I can see it now...Bowser in the summer of 2001 as the FBI hauls in twenty Muslims who were in flight schools under suspicious circumstances:

"Obvious persecution of a religious minority. Why isn't it assumed that these poor Muslims had perfectly valid reasons for taking flight training? There are Middle Eastern airline pilots, aren't there? And hey, everyone who works in a grocery store has a box cutter. What kind of idiots suspect someone for carrying a box cutter?"
