As George Bush's infamous for once saying by mistake, he said, "Mother Nature is a terrorist." So it was with Katrina - the devastation of it, when you think of bombs being dropped on people and then you think that a hurricane could come through and do that, the same amount of damage, it was a wake-up call in a lot of ways.

One of the most amazing things that came out of 9/11 was all the pictures taken by amateurs, by people just going to work or coming or saw what was going on and took it. But all forms and various types of cameras, and when you look at that body of work you just see the impact of how photography is - when I taught once, I said that you have to be ready now for any event.

You have this kind of cross between abandonment and savior, and I think it's going to show that how a government as powerful as America is was able to drop the ball so badly, then maybe it can be used as a textbook in the future.

These are the kind of things I always zero in. When I was in Rwanda, it was the same thing. You're always zeroing in those details. Not just always the bodies, but what makes up the human being.

I always believe you have to show the symbolism of a civilization, whether it be the cave drawings or somebody drawing in the sand in Darfur to show a massacre.

For me, Katrina was my first trip back to the United States, but the most important thing, it showed everything that I had seen in other places. As I've said before, it looked like a bomb had hit a lot of places. I'd never seen such force, and it was Mother Nature.
