I'm going to reiterate something that Mr. Cappe said, which is that it comes down to risk assessment. You have to get through the 90% or the 95% of people who aren't the problem, so you keep them out of the system, and you can do it on a fairly expedited basis. It's moving to forms like electronic travel authorization, it's getting our airport infrastructure into mechanisms like transit without visa—that's how we leap ahead. That's how we end up making best practices instead of following best practices.
