"[J]ihadist terrorism has been carried out from Bali to Casablanca to Madrid to London to New York City to Washington by young Islamic men of North African, Middle Eastern and South Asian origin. This is not a stereotype. It is a simple statistical fact. ... But the overwhelming odds are that the guy bent on blowing up your train traces his origins to the Islamic belt stretching from Mauritania to Indonesia. Yet we recoil from concentrating bag checks on men who might fit this description." --Charles Krauthammer
