Hi Richard,
My opinion is that the most important number is the ZERO cases reported. To my mind God's sole channel should have always been leading the field in its way of protecting children and dealing with abusers and that includes ensuring they are reported to the proper authorities.
ZERO means that the organisation is institutional in not reporting and I believe that up until this commission started to reveal their way of dealing with these cases they not only didn't report but they suppressed those who wished to with coercion, guilt-tripping and even threats of disfellowshipping.
I believe their prime response to an accusation of child abuse has been the preserving of their authority/image and the preserving of their money above all other considerations.
