No, he didn't. He went to the stockade for deliberately disobeying an order to deploy to a combat zone. He was making a political statement. How'd it work out for him?
LTC Lakin was not questioning the legitimacy of an order to deploy. He was questioning the legitimacy of Obama as POTUS, who admitted to being a citizen of three different countries AT HIS BIRTH, to give ANY orders to members of the Armed forces as an Article II qualified Natural Born Citizen. The birth certificate was merely a means to an end toward that determination. The distinction is significant.
There is no doubt in many people’s opinion (including mine) that Obama was never qualified as an NBC under Article II of the US constitution. It can be argued that Lakin was misguided and inappropriate as to his use of tools to effect the method of inquiry into this Article III matter. But I salute him for his courage and perseverance in upholding the oath of office that he took as an officer, no matter how Quixotic the quest.
I hope that president Trump issues him a full pardon at some point during his administration.
