Instapundit, law professor Glenn Reynolds, writes that Obama's disregard for his Constitutional oath warrants his resignation:

When taking office, the President does not swear to create jobs. He does not swear to "grow the economy." He does not swear to institute "fairness." The only oath the President takes is this one:

I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States.

By sending - literally - brownshirted enforcers to engage in - literally - a midnight knock at the door of a man for the non-crime of embarrassing the President of the United States and his administration, President Obama violated that oath. You can try to pretty this up (It's just about possible probation violations! Sure.), or make excuses or draw distinctions, but that's what's happened. It is a betrayal of his duties as President, and a disgrace.He won't resign, of course. First, the President has the appreciation of free speech that one would expect from a Chicago Machine politician, which is to say, none. Second, he's not getting any pressure. Indeed, the very press that went crazy over Ari Fleischer's misrepresented remarks seems far less interested in the actions of an administration that I repeat, literally sent brown-shirted enforcers to launch a midnight knock on a filmmaker's door.But Obama's behavior - and that of his enablers in the press - has laid down a marker for those who are paying attention. By these actions he is, I repeat, unfit to hold office. I hope and expect that the voters will agree in November.

That's a scarf wrapped around his face, not a "towel." Is the L.A. Times nudging us to think of this man as a "towelhead"? And look at this headline in the Daily Mail: "The man who set the Middle East ablaze hides his face in shame...." Shame? If I were imputing a motivation to this man, I'd say he has a fully justified fear of becoming a recognizable face.

He also joins Ann Althouse another Law professor who expresses  her  outrage at the taking into custody of the anti-Muhammed video creator, Nakoula (aka Bacile)

But I think our government is delusional if it thinks the people who are rioting in Africa and killing our diplomats would - if they knew the facts - see individuals like Nakoula as the proper focus of their rage. They don't believe the necessary premise: freedom as the superior value. As long as they favor a system in which blasphemy is outlawed and severely punished, they will continue to blame the American government for standing back and allowing blasphemy to flourish and flow everywhere. What good does it do to ask them to please understand our system? They hate this system.Meanwhile, our government would scapegoat a free citizen. It's not even effectual scapegoating.
