From The Christian Century magazine:

THE MIND OF THE BEHOLDER: Racist intent is often hard to prove, but what else explains why two similar photos distributed by the Associated Press (August 30) received very different captions? One photo shows a black male wading through chest-deep floodwater in New Orleans; the caption says he has just finished “looting a grocery store.” A similar photo of a white man and woman has a caption that says they were wading in water after “finding” food at a grocery store.
