The solution, IMO, ( IS TO BURN THE WTBTS TO THE GROUND ) is to instruct the Elders in an actual school and to have them pass background checks as individuals. Any prospective MS or Eldub should have to pass a background check. Then, if there is ever an allegation of abuse, trained Elders should try to help while simultaneously cooperating with local authorities.
That's one way- but it will never happen. They would need millions to leave Watchtower in order to have enough elders for the remainder. But I like that.
Instead, I say: TREAT IT LIKE A CRIMINAL ACCUSATION LIKE MURDER. If little Suzy or Johnny says that Brother Chester killed someone, the elders are not going to handle it, they are not going to refrain from reporting to the police. If they think Suzy or Johnny is lying, they aren't going to just forget about their accusation. They can stand by the child without judging them and they can accompany them as they deal with this tragedy if that's what Suzy or Johnny wants. Turn it over to professional people and follow their lead. If the Watchtower wants to retain that rule about 2 witnesses, they don't have to disfellowship the guy if that's not present.
