First before I say anything is that Evidence that warn is false doesn't always need to be a thing for things like this, read the dispute and read the admins dispute and find out what is right and what is wrong.
I was here in teamspeak listening, you were approching the guy while doing a "Back up or KOS" advert in chat which immendentily triggred one of these events. Next is I understand that PD SOP and or any or any other SOP says " You may use lethal force with a guy that can harm the public". BUT PLEASE for god sakes use common sense with this, the guy isn't pointing it at you at all why the hell would you shoot him for that reason? use common sense and your state SOP as you WERE TRAINED for these types of situations.
