So you made something up so you didnt have to acknowledge that is was crossfire...
2.2 Random Death Match - In order to kill or harm another player you require a valid role-play reason to do so. Crossfire is not an excuse for killing people nearby where you are raiding or shooting.
I've pointed out several times the KOS area isn't valid to an NPC, a dumpster, whatever it is. And as a cop
you should arrest instead of just killing even IF you have a valid reason to kill.
