In part:
The fact that New Orleans has not already sunk is a matter of luck. If slightly different paths had been followed by Hurricanes Camille, which struck in August 1969, Andrew in August 1992 or George in September 1998, today we might need scuba gear to tour the French Quarter.
And now looters are shooting policemen. Shot in the head, but expected to recover. Sure, but his life will never be the same.
Meanwhile, pure anarchy seems to be reigning in New Orleans. Where does one even begin to keep order?
