"An assurance that nothing like ir will happen again"?
The whole thrust of the priestly intervention is exactly to ensure that what has happened in the past is happening again, sweeping it under the carpet. The only thing we know is that it will happen again. My grandmother was sexually abiused by a Roman priest a hundred years ago, in Belgium. The society scandal which resulted was covered up with the promise Rome would not inflict itself on the family again. That counted as nothing, however, when a Mother Superior General saw fit to attempt to abuse my daughter for her own profit.

The one thing we know is that the only reason it's being covered up is not simply because it happened, but that somewhere it or something like it is still happening. If it were not, Rome could come clean with a Truth and Reconciliation clean-up to put the past behind it. One has to have a certain sympathy, as the problem may be so big it is unmanageable. The Pope has tutted, but will be off the scene before anything happens at this rate.
