You know it when the elders read this letter, they heaved a collective sign of relief because the WT took the decision-making out of their hands and they can sleep better at night knowing that the liability buck stops at WT headquarters and not with them.
While I will agree with the statment above and others on this thread, I think that one of the reasons that the WT is making this a policy to eliminate the possibility of any reporting to any authorities. Pretty much they are saying if any of you elders want to be preumptuous and report this to the police then you will be sanctioned because it is the branch that decides if someone is a molester/pedophile and not you. The legal and service departments at Bethel know that there are many "rogue elders" out there who could possibly ignore them and go directly to the police.
This is a direct threat to these elders that you will be dealt with if you do. Its part of their pyschological terror program and yes many elders will not go with their conscience and report abuse to police. Why go through that, why put your family through that. You could be deleted or worse disfellowshipped for brazen conduct.
