The white guys I saw were looters. There were a lot of black cops, too. This should be expected where the black population is the majority. Looting is not unique to blacks, although there is a "justification" usually given because they are "righting all the previous wrongs" against them. It is a bogus argument, anyone looting under these conditions should be shot on sight, regardless of race.
I think gas stations and oil companies who raised prices BEFORE the disaster "in anticipation" are no better, by the way. There should be a law against raping the public during a disaster. When the Raleigh, NC Honda dealer spiked his prices on generators during the aftermath of Hurricane Fran, Honda stripped him of his franchise. The same standard should be held to all businesses during disasters.
White people rioted in LA too. Savagery knows no racial boundaries. Haley was on the news yesterday and made it clear that in MS, they would be ruthless toward looters. I heard no "Don't even think about it" -style message from Kathleen Blanco. It's too late for most of America to ignore the looting... and it may be too late for any re-election chances she may have (or may have had, depending on how you look at it).

I know Florida has a law about price gouging in wake of a disaster.
