They don’t have a priest/pastor in their “churches” so no confidentiality between them.
There would be none anyway.
You can denigrate the Mormon church as not a real religious institution, but I'll take this reaction to child molestation over the Catholic church's every single time. You diddle a kid, you go to jail. You find out someone else is a kid diddler, you tell the police. You hide the fact that you know someone else diddles a kid, you go to jail. No exceptions for clergy, lawmakers, members of the British Royal family, or former Presidents.
