Tell ya'll one thing. I moved to Florida in 92, 2 weeks before Andrew. I went down a week before near Homestead to start working for my uncle in a construction company while I debated going back to college.
Andrew hit. It was by far the most devastating thing I had ever witnessed in my 20 yrs of life. Absolutely crazy. After the storm, the aid coming in took some time, but it got there, mostly due to the fact that the area was not flooded beyond reason.
Looting also happened. I sat at my friends house with a shot gun to discourage the "malcreants" from taking anything. Then an amazing thing happened. They shot and killed some looters. The looting pretty much ended after that.
Another amazing thing that happened, even though people were stranded, had no food, water, or medical supplies for days in some cases, they did not riot. You saw no one complaining regarding the food they received, the lack of response, or blaming the feds. You didn't see a mayor losing control of his behavior, nor did you see finger pointing.
You just saw people working together to help resolve a terrible situation. That's the key here. Work together, and get it done. Stop the finger pointing, that's the freaking bottom line.
