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.

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.

Today in America, we are trying to prepare students for a high tech world of constant change, but we are doing so by putting them through a school system designed in the early 20th Century that has not seen substantial change in 30 years.

We are on the lookout for criminal and terrorist activity but we do not - nor will we ever - monitor ideology or political beliefs. We take seriously our responsibility to protect the civil rights and liberties of the American people, including subjecting our activities to rigorous oversight from numerous internal and external sources.

Let me be very clear: We monitor the risks of violent extremism taking root here in the United States. We don't have the luxury of focusing our efforts on one group; we must protect the country from terrorism whether foreign or homegrown, and regardless of the ideology that motivates its violence.

Smart businesses do not look at labor costs alone anymore. They do look at market access, transportation, telecommunications infrastructure and the education and skill level of the workforce, the development of capital and the regulatory market.

And we ask the American people to play an important part of our layered defense. We ask for cooperation, patience and a commitment to vigilance in the face of a determined enemy.

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.

If American schooling is inadequate now, just imagine how much more obsolete it will be when today's kindergarten students graduate from high school in just 12 years.

Well, you know, I think in conversations with members of the Senate and others, they all recognize that the issue of immigration is important. It's important to our nation, it's important to our public safety, it's important to our security, it's important to our economic well-being moving forward. And it's not something that's going to go away.

I've appointed a task force to take a fresh look at the color-code system and whether we should retain it, change it or scrap it.

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

The United States and Arizona are both losing jobs to offshore locations.

All images generated by imaging technology are viewed in a walled-off location not visible to the public. The officer assisting the passenger never sees the image, and the officer viewing the image never interacts with the passenger. The imaging technology that we use cannot store, export, print or transmit images.

And I am also here to say that if something were to happen, we are prepared to respond swiftly, to respond effectively, and to respond strongly. That is our tradition as a country. And that is a tradition that we will uphold, regardless of any circumstance because this nation is one that is very, very strong and, indeed, extraordinarily resilient.

As part of our layered approach, we have expedited the deployment of new Advanced Imaging Technology (AIT) units to help detect concealed metallic and non-metallic threats on passengers. These machines are now in use at airports nationwide, and the vast majority of travelers say they prefer this technology to alternative screening measures.

But my view is that you need a system at the border. You need some fencing but you need technology. You need boots on the ground. And then you need to have interior enforcement of our nation's immigration laws inside the country. And that means dealing with the employers who still consistently hire illegal labor.

I have long been a proponent of a guest-worker program between the United States and Mexico, and in particular I have proposed that Arizona would be an ideal location for a pilot project.

I'm angry that the private sector, which is supposed to be in charge of running gasoline into the Valley, doesn't have its act together to deal with a critical situation, so now the public sector has to step in.
