PK or failed communication?
While failed communication does happen, due to misunderstandings and misinformation, I do have a strong hunch this was a PK.
Then consider yourself a wanted criminal, Mr. substance abusing backshooter Dope-Troll and go marry a swarm of bullets coming out of my gun the next time I will see you.
Hehe Deputy maybe you're good in killing blues by mining but in real PvP you're a shitty noob...:-)
