MG:

An interesting perspective.

It seems reasonable that out of the many priests who abused, some, possibly many were promoted to high levels within the RC organization. IMO, because there are many inside the organization, some who have not been found out, that fear they would be implicated. These people could have a lot of influence. And, implicating people at high levels could be seen as damaging to the RC church.

I suspect there is a fear that the (organizational) house of cards could tumble.
