To add another thought to Guy Who Thinks' comments above, New Orleans, like all big cities, has a drug problem. I don't know how severe NO's drug problem is, nor do I know how many drug addicts live (or used to live) in the city. But you can bet almost none of them evacuated or sought shelter. One of the main things an addict needs is a place to practice his addiction and in the Superdome with 20,000 other people doesn't really fit the bill.

And most of those addicts are now going into withdrawal because their suppliers either evacuated or are dead. As the authorities start rounding up the last few thousand people left in the city and forcing them to leave the city and go to refugee camps there are going to be a large number of very sick junkies, crackheads and meth-heads among them.

Just another item to be added to the list of issues the folks who are charged with caring for the storm's refugees are going to have to deal with.
