Most of the people who kill Americans tend to be Americans. Most of the violent maniacs and fanatics in America tend to be Americans. That's not picking on Americans, it's the same for pretty well any other country. If biometric identity stuff or whatever is seen as the only way to stop terrorism, it's no good just saving it for incomers.

I assume if thye are planninhg to bring in that kind of thing for incomers, that'sjust a way of softening-up people, before is introduced for your native population.

Whatever we do about frontiers, in Europe or America, the truth is it's just one permeable world.
