well when you see someone, bluesuit, no weapon out, running away from the encounter, i would say it is a safe bet that they are NOT pk, or at least not going to pk you. i don't know you or your charecter, all i know is i have been killed and shot at just for traveling to some town, and running into someone on the way, or people camping in the town. i may be new to this particular game, but even i know, if you act like a duck, quack like a duck, and walk like a duck, people are going to think you're a duck. substitute duck for pk, and it still makes sense. i don't have any problem killing if they attack me, but i would never just jump the gun and kill someone for happening upon me. if they want to fight, they will either say so, or fire.
