I know. My father who was in the navy was once escorting some foreign naval people from the War College on a trip to D.C. All kinds of foreigners, and who gets 'randomly' picked for a special search? Twice? You guessed it.
He said he got called aside for thorough searches almost every time he flew -- and he flew a lot.
On the other hand, I live in an area with very few Muslims (or at least few visible Muslims). The only time I ever see a Muslim is when I go to the airport -- it seems like a large percentage of the staff there are Muslims in full regalia. It gives me the creeps that working at an airport seems to be a primary goal of Muslim immigrants to this country.
