From this Sep. 4 post:
Some observers have said that because the majority of storm evacuees are black, the lethargic disaster response has a racist component. But Nagin cast the color issue in another light. "I think it's more a class issue than race," he said. "The Superdome had mostly poor people in distress. The rich have resources the poor don't. The Convention Center was different. There the poor were mixed with people from hotels and predators. You had blacks, Hispanics, Asians. The predators in there didn't care. When those stories come out, like children raped, with their throats cut, then somebody's got to answer."
