We must remember that, in order to expose the dreadful behaviour of people in authority, be it church or state, there is the risk of the exposer being accused of having known previously what was going on, and failing to act appropriately and in a timely manner.
The easiest way to avoid that potentially difficult scenario is to carry on ignoring it, and hoping it will just go away.
The Catholic Church, with its well-known and documented history of simply re-locating abusing priests, is the nearest they ever get to actually addressing the issue - which is to pretend that a re-location will prevent its recurrence.
It's rather like refusing to sell a savage child-biting dog, and simply giving it away to someone else.
