Yahoo! News - Video Shows 9/11 Hijackers' Security Check
"Surveillance video from Washington Dulles International Airport the morning of Sept. 11, 2001, shows four of the five hijackers being pulled aside to undergo additional scrutiny after setting off metal detectors but then permitted to board the fateful flight that crashed into the Pentagon."
No surprise there. At that time, airport security at Dulles Airport (IAD) was handled by Argenbright Security Inc., which employed many Muslims. Previously, the Council of American-Islamic Relations (CAIR) had sued Argenbright because female Muslim employees did not have the "right" to wear tablecloths on their heads. When I was going through security at IAD, I saw one of those gals in hijab just standing around, chewing gum.
I'm glad that Argenbright (now called Cognisa Security Inc.) and their employees are gone, but I do resent being selected by my domestic carrier for frisking, just to assuage the sensitivities of Arabs and Muslims.
