First I don't see what this news crew were doing wrong. It's good that there are prople out there testing the system. Fortunately on this occasion the system worked, but imagine if it didn't. I'd far rather have it fail with a harmless news crew than some real terrorists. At least then lessons can be learned before its too late!
Secondly to anyone thinking its xenophobic to target people of "middle eastern" appearance - tell me, how many of the 9/11 terrorists were not of "middle eastern" appearance? This is a fact, not xenophobia or racism.
