Go to the first link in post #1...you'll see a discussion in that Idaho case about all these lay people who knew about that incident.
You see, the Mormon church doesn't have any "professional" leaders. They're ALL lay leaders. And so whenever any of these lay leaders claim knowledge to such abuse, the Mormon legal reps & hierarchy rushes in and claims "clergy privilege" -- no matter who they are.
So you can't even tell in the Mormon church where "clergy privilege" begins and where it ends.
So every single lay Mormon knew about this incident? Every single one?
