From your screen name can we assume you’re actually a Tolkien fan?
Let’s assume you are for a moment.
When Denethor finally lost it and was about to burn Faramir alive, should Beregond have left his post to defend the intended victim, as the strict “law” forbid that he do?
When those in authority exceed their authority, and become in effect a law unto themselves, do not others have an obligation to stand against them, using the force that is within their control?
Is their oath to the authority of the officer above them, or to God-ordained principles of natural right?
I’m actually not a Tolkien fan, lol. Just answer my question about Obama and impeachment.
