Though I am unsure what server you play on not all of that is true to servers 2 & 4, I am a full time medic and true there are times such as when you go to get someone and they just re-spawn but a majority of the people who want to kill me tell me to "f*ck off and go away or I will kill you" state it to me then just rdm'ing me on the spot. If you are serious about being a paramedic check out the topic regarding white listed paramedics, it is an effort to give more flexibility to the EMT's and "fairness" if you want to call it that. And also the people above are right, simply report them or you can even talk to a moderator in the game, I have done it before and have had people banned for killing me infront of one.
