Agreed.
I don't think use of the military be required to remove his sorry self. Instead they might be called on to protect his ash before trial.
Neither. That's a matter for the civilian authorities.
Sometimes the civilian authorities will put a "high risk" prisoner on a military base. How much higher risk could one get than someone with the gall to usurp the Presidency of the US?
And although he wouldn't deserve the protection, I'd be OK with it. Just to watch watch him get what he would so richly deserve. In a civilian federal court, temporarily sitting on a military base. There is a certain amount of "assistance" the military can lawfully give to the civil authorities you know, and think this scenario would fall within those limits.
