This type of racial profiling hasn't just been a problem in the United States, as you saw from that article the problem is very prevalent in Europe. Also, in Australia where I'm from, about a year ago, a flight attendant for Qantas ordered the total and immediate evacuation of the aircraft. Everybody off, NOW...
What was the urgent and life threatening stimulus which triggered her reaction? Two middle-eastern men wearing robes and speaking Arabic. WWHHOOOOPS. Luckily she didn't speak for the whole of QANTAS and shortly afterward the CEO of the airline held a press conference in an attempt to reassure the arab world that they indeed wanted their business and that the actions of one woman with three braincells did not reflect the general feeling of the company.
COME ONN people, you can't not let people fly and have access to transportation just because they happen to look a little different and speak a different language to you. What are we back in the dark ages? What's next?? Muslim children of middle-eastern origin being turned away from public elementary schools because they happen to be different??

I'm not saying that the whole situation doesn't scare and worry me. It does. But there's no use stereotyping people and being prejudiced against the WHOLE demographic of arab people. This fight against evil and terrorism is only going to have a chance of succeeding if we fight for inclusion and equality rather than creating division and disharmony.
