I’d disagree with this wonderful and patriotic lady about only one point: she maintains that air travel is very homogenous, dominated by middle-aged, middle-class white guys. She must be only noticing the passengers who fly between New York and DC, as she does, because when I go to Dulles, BWI, Reagan National, Miami, DFW, LAX, or O’Hare, it looks like the United Nations. Especially Miami! No, it would not be easy to single out a Muslim there.
And the Chechens have used blonde Muslim women to blow stuff up.
And that ottbmare, is why we must adapt the Israeli way. You ask a couple of questions of those you "suspect", such as: Where are you going? Why are you going there? Who is traveling with you? etc. And while asking them you look them directly in the eyes and with training you know if they are telling you the truth. It is not rocket science as they say, but it is effective and works. Just ask them.
