Who's declaring immunity? from what?<quoted text>
No, the Vatican didn't micro-manage. They macro-managed.
That's why Bishops worldwide acted in a nearly uniform manner.
If as you claim, Bishops acted independently with little, or no direction from Rome, then the Vatican would NOT be hiding behind....
Holy Diplomatic Immunity!
Like a communist state, the Vatican state is a top-down, highly organized structure, with little room for individual initiative.
It would be impossible for individual Bishops worldwide to pull off a DECADES-LONG COVER-UP of this scale without direction from above.
To think otherwise is called "denial" and is absurd.
It isn't working if it's being invoked; the crimes are being prosecuted in their respective jurisdictions.
