“He fled the US to the Vatican lest he end up sued down to his sandles.”
Untrue.
He did not flee.
The authorities chose not to pursue a criminal case against him.
The Vatican removed him from his diocese and gave him a position at a basilica, basically as a fundraiser.
The Vatican then appointed another bishop to tackle the fallout.
Law’s diocese was sued.
I think Law had "friends in high places or something", right?
