I can personally say that in a few cases known to me in Canada (BC, Alberta) that the society still stresses that its the family or victim that makes the decision to report to authorities. The Canadian Bethel's instructions are to send to brothers to directly confront the abuser with the intention to obtain confession. No confession information is handed to the police.
The society feels that the elders have minister exemptions (which don't exist in many provinces). I know that when I mentioned that we don't have exemption the body said we have to follow bethel. Nothing like the moment you realize you have to leave these guys.
