NEW ORLEANS (Reuters) - When Hurricane Katrina slammed into New Orleans, submerging entire neighborhoods for weeks with its ferocious tidal surge, some say it was not a freak act of nature but a message from an angry God. 

That's the belief of some Christians in the United States, who have been warning the Mardi Gras capital, long known for its hedonistic ways, was bucking for a good dose of divine retribution.
