If you put your emotions aside you can see from a legal standpoint what a Pandora's box releasing files about every molestation case that has ever happened in a religion would be. It would open up the religion to even more lawsuits by those who were named--whether the accusation were true or not. Also, in the Conti case her lawyer was on a fishing expedition asking for that list. It wasn't really relative to her case from a legal standpoint. What was relative was what did her local elders do or not do. This wasn't a class action lawsuit.
Taking the emotion out of it no legal council would tell a company / religion / corporation to release a list of every judicial committee they've ever had in their history. That would cause chaos in that realm and you could never have judicial committees after that at all. So that isn't so unbelievable.
I think what often gets missed in all of these cases is the tragedy they all are. A person's life was ruined. What really isn't happening is that the perpetrator isn't really paying the cost they should. This is really a legal problem, because just like the two-witness rule the standard of proof in a court of law is very high and you usually need two people who were abused to get a conviction. This happens a lot in rape cases as well when a rape kit isn't taken right away. It's he said against she said and a lot of times the guilty person goes scot free.
All too often people comment on these issues with a bias eye--which is their right to do. But you have to look at things from all angles to come to a relative, well-balanced truth of things.
