I am not concerned with the numbers. People who know they are being watched, whether by police, their neighbors, or parole officers do not have the same access to children as persons who have never been arrested.
By allowing sexual predators to remain in contact with children, and not letting authorities handle the predators, the Jehovah's Witnesses become guilty. Are they guilty for every instance of abuse? No. But they are guilty when they knew someone was a predator (inside the family or outside) and did nothing to stop him/her from molesting the same child or another child again.
