To be entirely fair here, there have been blacks that have hijacked airplanes. I can think of one case in Africa right off the top of my head. Oh, and of course the guy that hijacked the FedEx flight. He was black. Also, didn't a white guy try to blow a plane up with a shoe bomb shortly after 9/11? There have been a lot of hijackings by Hispanics all over the world too... So if there is -any- kind of trend here its the fact that -all- types of people are capable of evil and malicious acts of terror.

And on that note, after being to the Middle East a couple of times the hair on the back of my neck stands straight up when I hear Middle Eastern men speaking in Arabic. Other than that I'm completely comfortable around them. The only people that I am seriously wary of are people of any color that act nervous, aggressive, or display almost any kind of suspicious behavior.
