I think the idea that you can go this alone is - was a huge mistake. And unfortunately, there was a price paid in terms of suffering and pain for people in New Orleans.

Well, I think first of all there was a failure to have real, clear information at our disposal. There was a real lack of situational awareness. We didn't have the capabilities on the ground to give us real-time, accurate assessments of the physical condition of the city.

We've done it in intelligence sharing and certain elements of security. There were parts of the department, in fact, that worked very well in Katrina, like the Coast Guard and TSA.

We've certainly learned a lot of lessons from Katrina, from Rita. Rita was better than Katrina. We're doing a better job planning. We're closer - more closely aligned with the Department of Defense. These things would be positive things if we were to have another attack.

Second, there are two problems with respect to mobile homes in particular. One is we obviously don't want to put them in a flood plain, because if there's another flood, you're going to lose the mobile home.
