This may be the incident that ended Barack Obama's chance for a second term. Here is an ABC News report. Here is a blog post from Power Line.
Addendum: Nothing I have read so far about this incident, including this, makes me think that it's about race. It's about class. President Obama instinctively sided with the Ivy Leaguer and against the working-class police officer. I believe he would have done the same had the arrested professor been white and the police officer black (all else being equal). Do you agree? At a minimum, there are elements of both race and class involved. Why is nobody mentioning class? Why is every incident essentially racial? Oh, wait. I know. There's a race-grievance industry in this country. It's in the interest of a great many people (including academics) to keep race salient, to reduce all disputes to racial disputes, to create racial "identity," to encourage certain people to think of themselves as victims of racism, &c. The irony, of course, is that progressives say that race is not real, while doing everything in their power to keep it at the forefront of people's thinking.
