I’m not sure Archbishop Vigano has any further evidence to vindicate his claims.
I’d like to think that he brought copies of incriminating dossiers with him, and has held them back, giving others the oppotunity to show good faith and true pastoral care by revealing them first. And now, that they are not stepping firward, bur rather are participating in the cover-up, he will reveal the evidence.
But I think that is likely wishful thinking.
The evidence that is out there partially vindicates him, but with regard to his primary claims - there doesn’t appear to be a smoking gun.
So, those who do evil will continue to operate in the dark.
How? They are so conveniently outing themselves by taking sides against getting to the bottom of the evil.
