The USA is one of the few countries that has NO (official) exit controls for checking pp's; I assume that when I make a reservation for an intl trip, and I am required to give my pp number to my airline that they have cross-checked it with Interpol(?)--if not "we" are no better (maybe worse) than (say) Malaysia.
PS: I am NOT saying that catching people flying with stolen pp's will have any effect on flying safety; if (as in the case of 9/11) the hijackers were on a suicide mission, why should they care about using stolen pp's?
