I hadn't paid much attention to the story of Shirley Sherrod. She is the USDA official who was forced out of her job for making allegedly racist comments in a speech to the NAACP. According to this piece from Peggy Noonan, she was treated unfairly by many commentators AND the Obama Administration.
It is a lesson in the importance of learning the truth about a person and their actions. We are all potential victims of a 24/7 news cycle and instant-publish news and commentary.
