1. It's patently obvious that this is a fraud. It's obvious that the woman put that on her own face, and it wasn't done by a 6'4" 200lb black man with a knife! This looks like she just scratched it on there, if it were done by an angry blackman with a knife, there would be a LOT more blood and the cut would be much deeper. This is due to the fact that she would have obviously been resisting and it wouldn't have been possible to make such a benign looking mark with a knife. Plus, She refused medical treatment? Looks like someone wants to be a martyr...
2. EVEN IF this is not a fake, Is it really surprising that there are a lot of crazy Obama supporters? There are crazies in every camp, and that includes Obama's. You can't judge a political candidate based on what a few psychopaths do in their name. Otherwise no political candidates would be qualified.
