First of all, prosecuting for treason is not 'rounding up political opposition'. That those so prosecuted are politicians is irrelevant. They are going for their deeds.
As far the requirement that one be in the military in order to fall under a military tribunal's jurisdiction is similarly in error. FDR executed both civilians and military saboteurs in WWII. Including US citizens. Anyone participating in conflict without gov't sanction is an unlawful combatant with no rights, can be killed in the field, taken prisoner and tried by tribunal.<[> The WWII saboteurs paid the price under this definition even though the military members were operating under sanction:
Unlawful Combatant Definition: A combatant who does not act under orders or with a distinctive uniform and conceals arms and otherwise ignores the laws and customs of war. Related Terms: Enemy Combatant, Prisoner of War. A terrorist is the classic example of an unlawful combatant.
Here is my actual statement:
Trump is NOT going to go down in history as the President who rounded up political opposition and denied them access to the full process of law.
The U.S. has never had a failed conspiracy like this one; but, our institutions are up to it.
As I stated before, there may be some exceptions that can be brought before military courts, especially where the criminal acts were conducted within the Top Secret branches of government and hence cannot be afforded a public trial. But this is never going to happen to most of them.
Right now, I think Barr and others are wrestling with the fear that if they bring all the conspirators to trial, some of them will be found NOT GUILTY by the juries.
THAT IS THE AMERICAN WAY! Personally, I would be satisfied with 100 trials and 50 resulting in convictions.
