Wolf Blitzer was the one who observed off the cuff that the Katrina refugees he was seeing were "so poor, and so black"
I am by no means a defender of Blitzer--his interviews and his framing of issues show him to be a banal thinker--but I feel he received a lot of undeserved criticism for this utterance. Which seemed at the time to mostly come from bad-faith actors like Rush Limbaugh, taking a cheap shot.
