Landy: With the exception of crimes committed against minors it should be victim who reports the crime to the police.
In an ideal world, yes...that is what should happen.
I think the issue of reporting crime to authorities could be solved very simply: remove the elders from the equation. The elders shouldn't be involved until after the crime has been reported to the police by the victim(s). The elders should be there for the congregants in the role of support and counselling.
The WTS could fix this problem so very simply. All they have to do is announce that the congregation should consider going to the police first in the case of serious crime like child abuse. The congregants could easily be told to go to the police themselves....like the rest of the world does.
As far as the OP's question goes...which crime should elders report?...I think there is a problem when a person places serious violent crime, like the rape of a child, in the same category as pickpocketing. The one crime results in grievous bodily harm and the other is a minor property crime. Surely the elders and others can distinguish the difference between petty crime and crime that causes serious physical and mental harm. Surely to gawd they can...
But,...I suppose the WTS has a problem categorizing what they determine to be the "sin of fornication" in the same category as "grievous crime". After all...the bibble doesn't really speak out against raping children, does it? Or against beating up women, does it?
