I watched it like 10 times. To me it looks like wrong place, wrong time. I don't think he deliberately hit you, but that's me giving benefit of the doubt. Its a short clip which really doesn't show us anything. I have no clue where you are on the map. If its a red zone you are KOS anyway. If hes in a gang your at war with he can just kill you. There's a reason why they ask for 5 minutes of video evidence when you submit a report.
Instead of posting saying how shit the staff is here, why don't you give us all the proper evidence. The lack there of makes you look stupid.
