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 going to do with cyber-attacks - and we have already actually started - we started well before the executive order actually was issued - is working with the private sector, determine how best to share information, because, you know, we can't help until we know that there has actually been an attempted intrusion or attack. Information-sharing piece is very important.

We have at least 125 communities in Arizona at risk from wildfire, not because of review processes or litigation delays but because of a lack of federal funding on the ground to actually begin the projects.

It would be unwise to say the least, irresponsible of us at the TSA, at the Homeland Security Department not to evolve our technology to match the changing threat environment that we inhabit.

Such a system would be very, very expensive and laborious to have, given the kinds of border we have. Scientists and engineers aren't even sure they have the technology to make it work

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).

You can't imagine a world, quite frankly, without a safe and secure aviation system. And so our job is to really focus on that, and what we need to do to keep it safe and secure.
