Heydog. The WT policy and procedures on child protection don't work in practice in far too many cases.
The Australian Royal Commission proved that much beyond all doubt. It was beyond embarrassing. I'm afraid that, like many well-intenioned JWs, you have a naive perspective that confuses theory and practice. Literally thousands of victims — many of them abused by abusers who were known to be such by elders — can testify to the fact that it does not work. The organisation has paid out countless millions in compensation and hush money in recent years in a vain effort to cover over past failings.
You lived in a state with mandatory reporting laws. In many states and many countries this is not the case. The first directive of WT policy is ‘don’t bring reproach on Jehovah’s name’. This has consistently trumped child-welfare.
You looked for ways to get around the two-witness rule — well done. Frequently the organisation has used the rule as a way to protect its reputation.
The Watchtower’s record in protecting children and in dealing with cases of abuse is no better than the Roman Catholic Church. In recent years the Vatican has been forced to take steps to acknowledge their past failings, apologise to victims and change their ways — The Watchtower remains defiant.
If local elders are doing better now than past generations that is despite the leadership of the Governing Body.
