Prime I agree with you on one thing, and that is that the law is flawed as it related to faith based organizations. That is no doubt because of the fendamentalist zealot nature of our predominantly Christianized culture. But these are some key things you are missing not with the mind, but with the heart.
If the organization is no part of this world, why do their personal steps not go farther than the worlds in this regard? Why keep information secret? Objectively it is difficult for someone (with or without an agenda of sorts), to look at the sanctioned actions of these congregations which are not in principle autonomous, and say that the well being of the image of the organization was not the paramount concern.
In discussing this case with some brothers locally, they told me they wouldn't want to get "involved with the police". I asked them why not, and they were afraid of being sued. Unbelieveable. These brothers came off as pretty intelligent, yet here they were with absolute ignorance guiding their decisions.
The sad fact is that if a child approaches them with an allegation of molestation, its a slow and go method of INTERNAL investigation, when the policy should simply be that the authorities are notified of the accusation. Then if they want to investigate internally its all good! In addition, if a former abuser comes into the hall, this should not be information that only elders and their spouses (and friends), are privy to.
From a biblical perspective, shouldn't the "spirit" of the law be what JW's try to hold to, and not worry so much about the letter of it? It just screams hypocricy. That being said, I think JW's don't have more of a problem with this than society as a whole. But they are not handling it correctly by their own standards that is for sure.
13-15 year olds are still minors and easily manipulated. You mgiht want to re-think that viewpoint.
Elders are hardly qualified to investigate a crime, wouldn't you say?
