The outrage with revelations of veteran child abusers is not the person themselves, but the [Meah She’arim] community leaders whose idea of a non-governmental-solution was to kick him out of the neighborhood — so he could endanger both Torah observant and non-Torah observant “outsiders”, instead!
Surely a child-abuser is a rodef, since פיתוי קטנה אונס, beyond the capital offense, but even if you don’t want to use government enforcement, employ the private custom toward rodfim.
If this was the Badatz, and this is the Badatz’s idea of Din Torah…!
