First off like another guy just stated. When you enter a PvP controlled area you get a message in big Red letter warning you of this before hand, and the count down gives you the chance you need to leave, by ignoring the warning you are there by accepting that the risk of being attacked, mission or not. Myself as a PvPer if I encounter a player in a PvP area or see one that is flagged, I won't just ignore them and will attack on sight, weather the target fights back or not my goal is simple. Defeat a enemy that is a threat to me. But in the end you were the one to make the choose to enter a lawless area. Some advice to you is if you wish to avoid being attacked in the future, is to not enter any PvP areas.
