1st clip.
Where is the admin abuse? You are claiming they are breaking a rule. You should be making a player report on the forums rather than making a sit to complain about something that a Moderator can't deal with. You know a moderator can't deal with this sort of sit due to the rank of player you are reporting. Website -> https://gaminglight.com/forums/forum/111-report-center/ this might help you.
2nd/3rd clip is even worse.
Firstly, why are you showing evidence to someone else but not the person who is higher up and assuming will be the one to make the final decision. Showing evidence to someone else and then saying "Take my side" is not convincing enough. Evidence needs to be shown by the one dealing with the sit.
Secondly, you did RDM the dude. Yes, he had a weapon out and yes he was facing towards you. Does this give you a reason to kill him? No. It is only KOS if the player goes inside the the circle, which he did not do. You can't just shoot someone just because they have a gun out. It looks here like you were itching to find a reason to shoot someone, either because you don't like them or just didn't care enough to actually roleplay.
The correct way to go about the situation would of been to either, warn the guy using adverts or just waiting for him to initiate combat with you. He had full right to kill you as you were inside, but you DID NOT have right to kill him as he was not inside a PVP area.
Once again, where is the admin abuse.
Quit crying and play the game. You seem to be more bothered that you're losing points while in a sit over anything else lol
