"But then I think we have to, with some degree of wisdom, come to the following perspective. We're never, ever going to be able to totally control immigration to a country that is as large as ours, that has borders that are as diverse as the borders of the United States, and as a society that wants to be a country that values freedom -- that values freedom of movement, freedom to do business.

If you were to totally control immigration into the United States, if you were to totally control the flow of people in the United States, you might very well destroy the economy of the United States because you'd have to inspect everything and everyone in every way possible. I don't know that there's any technological way to totally control it. There's no doubt much better ways to get more of a reasonable degree of assurance about who's coming in, to get more control over it, you're never totally going to control it. So we just have to accept that if we want to be the kind of country that we are," - Rudy Giuliani, a decade ago.
