You were not the acting commander, you did however take commands side when you refused to stand down when we asked thus making yourself a hostile. If you didnt want to be a part of the mutiny just scream that you surrender and you wouldve been left alone, you did not want to surrender however. You were not uninvolved, you became involved when you dropped a mutineer with a pistol burst.
The marines started dogpiling you, there is no requirement that we cannot disarm you, the only requirement under the rules is that we dont immediatly open fire on you on sight and give you a chance to surrender, you didnt surrender, got up, and shot one of the other mutineers until he was dead. I was also not the only one shouting for you to surrender, pretty much every mutineer including the mutiny leader was screaming for your surrender.
Yes MPs MUST follow marine law as a rule, which means they are required to provide medical treatment to all prisoners. You were afforded every protection under the rules.
I did not attempt to perma kill you, nor did i try and make sure you got no medical treatment. You were not uninvolved thus you were attacked.
