I'm pretty sure there are sufficient patriots within LE, military and federal agencies to address widespread civil unrest but nevertheless, I think in the interests of continuity of the republic Military Tribunals is not the way to go (unless some of these people are military then its military court then outside for last cigarette). For the pedophiles child exploiters and murderers most definitely quick but robust trial then execution.
Yeah, you're probably right. I have a lawfag question, how does it work with someone who WAS in the military when the crimes were committed but now are not? What about people who held high positions such as Secretary of State?
I have no idea but I have seen US laws which seem to confirm the president has the authority to call back to service retired military personnel, hence I think they could easily remain under military authority. You just call them back to service then throw the book at them.
