But my primary objection isn't the totalitarian potential of national IDs, nor the likelihood that they'll create a whole immense new class of social and economic dislocations. Nor is it the opportunities they will create for colossal boondoggles by government contractors. My objection to the national ID card, at least for the purposes of this essay, is much simpler.

It won't work. It won't make us more secure.

In fact, everything I've learned about security over the last 20 years tells me that once it is put in place, a national ID card program will actually make us less secure.

(many potential problems described)

Proponents of national ID cards want us to assume all these problems, and the tens of billions of dollars such a system would cost -- for what? For the promise of being able to identify someone?

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.
