Disappointing words from Rhee

I feel disappointed by Michelle Rhee, the DC school chancellor's words (read more here). Rhee's become the educational reform movement's main girl and the source of hope for many. I'd like to be confident in her leadership, I'd like to know what she says means something for children. This article points to some disappointing accusations she's making against the fired teachers. I'd like to believe that this is the case--many fired teachers needed to be pushed out. However, I know of several teachers who were the exact opposite--excited, motivated, working hard. She would be better served by throwing excuses around and working to motivate the teachers currently in place.
