To put it bluntly, if you think that's true, I want nothing to do with you. If it is true, I want nothing to do with your God. These people give both humanity and Christianity a bad name. Besides, if God did this to punish NOLA for being a "wicked city", he sure as hell took his time!
By the way, has anyone heard verifiable reports that the New Orleans police have started joining in the looting?
