I've discussed this possibility too. His lawyer has got to do his best Perry Mason impersonation against a stacked deck.
LTC Lakin's lawyer's problem will not be a "stacked deck," it will be that he is asking the Court Martial to over rule the United States Constitution, and make the United States Army, not the Congress, the final arbitrator of who is, or is not, the lawful President of the United States. Anyone who thinks that the Army will set its self up to decide who is President, much less decide that Congress got it wrong, and start obeying the orders of its own choice to be President, and ignoring the orders of the guy that Congress says won, is delusional.
