CTL, someone with semicha might have an extra claim to a religious exemption as some authorities say that Rabbi Eleazer b’Rabbi Shimon was only wrong (Baba Metzia 83b) becuase a talmid chacham should not engage in such activities (Bet Yosef Choshen Mishpat 388 near the end of the siman). I do not know about other religions but it would seem logical that they would have similar attitudes. In any case, I remind you that I wrote “probably” not “definitely”. Please learn the proper use of the English language. You yourself implied that in some jurisdictions there is an official clergy exemption.
Litebrite, a rodef is not necessarily someone who is threatening one’s life. he could even be a forger (Rema Choshen Mishpat 388,12).
