Rich, I just returned from New Orleans after two weeks. Though the death toll, is "little more than a 1000", that number doesn't do the scene justice. I also went over to Gulfport, Waveland and Biloxi. Waveland has no standing buildings, none. The only standing structure I saw was the remnants of the vault at a bank. Burglaries, small-scale looting and a few felonies were still present.
99% of the people I made contact with were very happy with our presence. All wished we had been there sooner. Most begged us not to leave. There is simply not enough local and state infrastructre to keep law and order, provide medical support, food/shelter, etc. I worked with many of the ARNG troops. Very professional, conducted themselves as expected, and integrated very well into the LE force. Many of the NG troops are cops, so this was not a problem. There were LE agencies from all over the US, and we all felt the same. No city or state could handle this on their pwn. A national level effort with a centralized command and control was required for the aftermath.
From where I stood in the muck of it all, the President was right to not only federalize the area, but to keep the resources there longer than what some wanted. It will take a long time for those cities to revitalize.
