Why?
The US military has accused him of disobeying a lawful order. The elements listed with Article 92 say that an order is lawful if it is not contrary to the Constitution or law and if it is not given by somebody acting beyond their authority.
So Colonel Douglas was expected to prove his authority every time he issued an order? Did LCOL Lakin have to whip out his commission and show it every time he gave an order to a subordinate?
And we know that Joe Biden is the only one who the Constitution allows to act as President, since Obamas birth facts have never been legally determined even now, much less by the deadline of Jan 20, 2009.
We know that you believe that to be true.
Do you acknowledge that there are some orders which can only be given by the CIC?
If Lakin had ordered his underlings to go to Iran and fight the mullahs would you expect him to have to show some authority for being able to give that order? Or would his underlings just have to go invade Iran without question?
