I was an officer chasing you down for speeding. I tried to pull you over and talk to you for speeding. You decided to stop at a police department, get on duty and kill me and a fellow officer I was with. You clearly had no reason to kill us, what you did was purely deathmatch someone who wanted to engage a simple roleplay with you. I didn't pull any gun.
As for your chat, it could explain why you didn't respond, but it didnt explain why you choose to deathmatch. What I understand is that you choose to shoot because someone was shooting you?
