You have the implication correct. As for innocent until proven guilty, that's a worthy concept. Personally, I fought to keep my buddies and myself alive. You can come up with all kinds of lofty notions about why people fight and die but the fact of the matter is...it all goes out the window when you are faced with your mortality each and every moment of the day. If you were ever in battle, you would know that !
I suggest you do not cite legal precepts and the Sulja incident. There is no parallel.
