I know personally elders that have made anonymous calls on alleged abuse to law enforcement even before a call to Bethel is made by the committee.
A witch hunt begins amongst the BOE but like all well trained elders know, deny, deny, deny, usually works well.
These instances are probably still rare, but I don’t think it is too far fetched to assume they may become more frequent.
WT is always moving away from protecting individual elders legally and elders are becoming wary of putting their own necks on the chopping block in a court of law and the monetary demands it takes for litigation.
