With all the evidence stacked against them on child abuse issues, why do you think they are still refusing to play ball with the authorities? Why not put their hands up & say "We got a problem, we need help to change our medieval policies, we need advise on how to conduct our affairs in away that is in the victims best interests".
Do you think that it is blatant, selfish pride. The risk of losing money & struggling as a consequence, or they truly believe that Jehovah is protecting them & by admitting they have acted in this inconceivable way would bring reproach on his name?
