As far as I can deduce, most suicide bombers (in their various guises) commit the act only once.
Mostly they are recruited from "normal" families, and from various parts of the world (including the UK a few months ago in Israel), having committed no crime previously. What are fingerprints and a photo going to do? Maybe provide Fox News with an instant image to show the nation rather than the torn body parts that would litter the streets? I hardly imagine Bin Laden stepping off a flight to JFK suddenly thinking "whoops, caught out by the scanner!"
As for American comments on state sponsored terrorism in the Middle East, an awful lot of people query the American relationship with Israel and its apparent double-faced attitude to acts of terror, but that's not for this forum
