Hi
Whilst it appears the other players involved in this interaction had similarly committed rule breaks, I do believe that there is a degree of responsibility for multiple of these events that lies on your NLR. As a cop, you can return to scene if specific circumstances are met, and you are called in as back up, etc. but your initial return to the ghetto is not necessary and does break the NLR rules. I also believe that running the other guy over and then executing him was a mistake and not how you should have handled the situation. It seems more like you held a grudge after your previous encounters.
Regardless - In this instance I'm happy to reduce your ban to 12 hours, as it is your first offense and the other players involved clearly have some guilt in the matter. I also appreciate the detail put in to your ban appeal, and the opinion of the banning mod.
