I watched a guy stalking three people at the NWaf. I Came up and told him to put his gun down and he raised it at me so I killed him. A few minutes later I was shot and inexplicably with a mosin. The three guys came up and tried to help me but got shot at and one of them died. He was definitely killed unfairly but the sniper may have been the friend of the guy I killed. Is that against the rules?
