The Cain Oath of Loyalty

When Presidential candidate Herman Cain said he would require any Muslim appointed to his Cabinet to take a loyalty oath liberals went crazy. They screamed about how "un" American it was to require such an oath. After all, they said, this is America, land of the free, so why should a loyalty oath be required? From the liberal perspective this is certainly understandable. After all when government employees leak confidential information it is a good thing; right? Well maybe. If it is about mismanagement, political firings, and inappropriate activity I can see that. But if it is about information that informs our enemies such as the exposure of wire tapping methods, CIA "black camps" used for questioning terrorists and secret military strategy information, maybe that is different. So obviously it then becomes a question of discretion, which requires thoughtful consideration and adherence to the law. That is, no government employee is required to break the law for a superior. I understand there is a grey area here, but that too is governed by internal agency rules and regulations. The point is that, Cain's statement aside elected and appointed officials and military volunteers already take an oath to protect and defend the Constitution of the United States. Those that fall short violate that oath, regardless of race, color, creed, or gender.
