One of the main factors why its important to report pedophilia to the authorities is that its known that these people have a physiological condition which as such that they are prone to re-offend, even after they've been exposed and caught.
The real core problem the WTS has with dealing with pedophilia within their organization is that the WTS wants to hide these occurrences from both inside their organization and outside as well.
Keeping a pretentious clean image of the organization is more important than protecting children from this awful behavior. "Mustn't bring reproach onto Jehovah's organization" is the indoctrinated mantra and that is the background initiative by the Watchtower Corporation from the Top down.
If the WTS was smart they would be adamantly aggressive to rid people away from their organization and let the legal authorities do what they perceive to be the proper handling of these situations..
From there they could boldly say that they deal with pedophilia differently than other religions but in reality they handle it just like the rest of Christendom. .... they hide it.
