SNAP should consider themselves successful in this regard - the Catholic Church, at least in the US, has a ZERO POLICY of any form of sexual abuse.  Upon any credible accusation, the accused priest, religious person ( sister, monk, deacon...), or lay persons must step aside from their duties until the accusation is investigated.  Only until the accused is exonerated can the person resume any duties that may entail contact with others.  

In recent years, you can count the convicted on one hand and have fingers left over.   There seems to be very little or no opportunity for SNAP to sue for damages.   No money, no organization.   After all, that was the driving force, wasn't it?
