The thought I have is that we do a lot of work around the world, and I see each country struggling with how to make our borders stronger. As I speak with people, they have countless examples of gaps in their system, just as I talked about here. I think everybody around the world is struggling to tighten those. Some are further ahead than others.
We don't carefully screen the people who are coming in from a face recognition point of view. I think one can also look at exit controls. I don't think we have any exit controls. So part of what we'll get to in the “Beyond the Borders” initiative, at least on the U.S. border, is some exit control as well.
