Well, you know, the violence is mostly in Mexico itself, at least the violence that people are worried about. And so we want to make sure that violence does not spill over into our communities that are along the border.

What we're doing is making sure that we have a safe and secure border region from San Diego all the way to Brownsville. And that means manpower, it means technology, it means infrastructure, it means interior enforcement. All, you know, kind of layered in appropriate ways, and making sure, like I said before, the border is safe and secure.

Each and every one of the security measures we implement serves an important goal: providing safe and efficient air travel for the millions of people who rely on our aviation system every day.

The last thing the Department of Homeland Security is about is infringing on anybody's constitutionally protected rights.

I believe that Streamline should be part of our toolbox of things that we use at the border. And there needs to be a variety of things that we use at the border to get the most effective enforcement strategy. And so really it's a resource issue more than anything else.

Now, a lot of what we are doing right now, quite frankly, is because of what happened on Christmas. Many of the things were kind of in the works. We were already planning, for example, the purchase and deployment of advanced imaging technology. You call them body scanners. We call them AITs (Advanced Imaging Technologies).

It is fair to say there are individuals in the United States who ascribe to al-Qaeda-type beliefs.
