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.

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.

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.

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.
