If "going to the cops" entails repealing the priest-penitent privilege, a repeal for which there is no small support, then skepticism is indeed warranted. Pederasty isn't the only threat, and we are fools if we think it is.
Penitent? What penitent? I don't see a penitent.
Actually, the quotes from psych reports and comments I've seen in the newspapers seem to agree that these guys don't think they're doing anything wrong. They're more like hetero rapists who insist the woman wanted it.
