People stand next to piles of garbage outside the Superdome

UNITED STATES - CIRCA 2002: People stand next to piles of garbage outside the Superdome in New Orleans as they wait to be evacuated from the city in the wake of Hurricane Katrina. Days after the hurricane hit, New Orleans has descended into chaos, with corpses littering the sodden streets, snipers firing on cops and rescue workers, gangs of looters taking anything that isn't nailed down and thousands of people sweltering in the steaming city without food, water or shelter.
