It appears I've made an enemy.
Situation: Player enters the police station where I am sleeping. Player destroys generator, takes a swipe at a few high-level players, and jets. I add him to my contacts and code him red so I know him as a possible PKer should I encounter him again.
When I log back in the next day, I go over to a nearby hospital to pick up some FAKs, and Player is there with two others. I am almost out of AP so I warn them that Player destroyed a generator at the PD and then go back to my safehouse.
Today, Player comes back to the PD, attacks me once, and leaves a semi-threatening, poorly spelled message. Then he jets again.
So, my question is, who's the jerk? Me or him? Did I violate some sort of unspoken code or is he just pissed that I blew his cover before he could destroy the hospital's generator? (I went back over and the hospital is fine.) I feel like this guy is after me now but I guess he could have killed me in my sleep if he really wanted to.
