Now I Get It: I get it now. If you're white, you find things. If you're black, you're looting. - Scott Roeben, Las Vegas, NV
Scott has a good point. Both the above links come from Yahoo news photos - that is seriously biased reporting. Taking groceries from a grocery store seems like a reasonable survival tactic to me - looting is when you steal stuff that you don't need.
Caption for photo of two white people: "Two residents wade through chest-deep water after finding bread and soda from a local grocery store after Hurricane Katrina came through the area in New Orleans, Louisiana."
Caption for photo of black person: "A young man walks through chest deep flood water after looting a grocery store in New Orleans on Tuesday, Aug. 30, 2005." (though to be fair he is carrying a box of Pepsi and a large black bin-liner - saves making more than one trip to the shops I suppose).
