Gee, I don't know, do you? Once you have finished your investigation, come back with your results. In the meantime, this guy is going to prison. Once you get your numbers of Protestants, then come back and tell us that this loser shouldn't go to prison because X number of Prots abused kids as well, so it is all right.
I do not have the answer to how many Protestant ministers have been caught sexually molesting minors. But I would be willing to wager the number is no where near the number of Catholic priests caught doing it.
