I didn't read this entire thread because most of it was retarded, but like I said on another post...
Nearly 70% of the New Orleans population is black. Then consider that nearly a third of the population is below the poverty line, almost all of them black, and they're the ones who couldn't get out of the city.
So who would you expect to be looting? The only ones left in the city: by and large the blacks.
It's demographics and chance, not some underlying racial trait.
