So Associated Press, the sold-out media organization

wanted proof of a negative. Which is bullshit. So Breitbart raised the ante:
Andrew Breitbart raised the stakes by offering a reward of $10,000 to anyone who could prove a Tea Partier shouted the "n-word". Despite the dozens of video cameras on the scene, no one has yet claimed the prize. Next, the Associated Press attacked Breitbart in a "news" story, saying that he has no proof that the incident didn't happen. In response, Breitbart has now raised the reward to $100,000.
And nobody has tried to claim it. Gee, I wonder why...
