I admire your fairness but i feel that this may be based on some idealistic notion of the WTS.
My personal opinion is that it is ultimately the parents' job to report the matter. It is the congregation's job to inform them of their right to do so--and to explain the clear reasons why it's necessary. If the parents don't do it, then the congregation can report the matter. I think, up front, before the judicial committee even begins, the elders should refer the parents to experienced professionals in the area of child sexual abuse.
This doesn't happen in "real life". I readily think of one Australian poster BLISSISIGNORANCE who was DFd for actually reporting!
In response to the other point quoted above, isn't it the whole point at issue that the WTS' interferes in the victim's natural justice? Just speaking about "the congregation's job" etc is an indication that they have taken it upon themselves to set themselves above the law - they decide. That's disgraceful!
Now with regard to your initial point that further acts of a similar offense may be taken into consideration just isn't good enough. For this to work, the offender has to be caught doing it again and surely that then places innocent victims at the mercy of the dub system of so-called justice. What is dealt with in the courts of law is the crime right here and now; they don't wait for it to happen again and say, "Oh well, maybe we could consider that other case in conjunction with this one."
So, no I cannot agree that the whole paedophilia issue in the JWs has been over-stated, and neither to the thousands of dubs who've left!
