I wouldn't say we aren't getting anywhere. Certainly we have a lot more activity and awareness of the problem, and we've been working within the existing framework to address it. So there is a framework in place that we can use and we are using.
We are using increased cooperation with our partners internationally, specifically also with the U.S. and Mexico, because we do have integrated borders and things like that. So it's not that we're standing still on this. The improvements to our own domestic regime are one part of the puzzle, but we haven't been standing still.
