Here's stunning video of Barack Obama hearing live the news of the commutation Scooter Libby's sentence for perjury. It strikes me as revealing that Obama immediately sees a parallel to the way a young black man is being railroaded by the justice system, with no recourse. Yes, Bush had no power over Genarlow Wilson's sentence. But the contrast is striking - and corrosive of confidence in equal justice under the law. When such injustices are a common occurrence among the poor and marginalized, the special treatment meted out to one of the president's friends is particularly galling.
