If we were talking a competent mayor, I would agree with you. While I agree that getting tax revenue would be important, I cannot imagine Nagin thinking that far ahead. He immediately blamed everyone but himself when the shiit hit the fan. As more information gets out, he is looking worse and worse. IMO, this was to be a PR move, nothing else. Now, he has another hurricane to possbily deal with. Stuff is not ready for people to move back.
