What good would it have been to know the names of Timothy McVeigh, the Unabomber, or the DC snipers before they were arrested? Palestinian suicide bombers generally have no history of terrorism. The goal is here is to know someone’s intentions, and their identity has very little to do with that.
And there are security benefits in having a variety of different ID documents. A single national ID is an exceedingly valuable document, and accordingly there’s greater incentive to forge it. There is more security in alert guards paying attention to subtle social cues than bored minimum-wage guards blindly checking IDs.
That’s why, when someone asks me to rate the security of a national ID card on a scale of one to 10, I can’t give an answer. It doesn’t even belong on a scale.
