Who in their right mind would trust their 10 year old girl or 8 year old boy with a grown man? --and then blame the watchtower using your excuse. - Fish
WT is not necessarily to blame for the abuse occurring. It's what they do once the abuse is reported to Elders which is the problem. In many locations, even allegations of abuse are to be reported to authorities.
The other issue with WT is not warning other congregants, especially those with children, when a member has a history of abusing children.
WT claims the member with a history will be watched and not permitted to preach D2D on their own. No one can be watched at all times and there is nothing to prevent any person from going D2D on their own. Even if accompanied, the other person may not necessarily be aware of the offender's background.
In regards Australia, I understand it was 1006 offenders. As some offenders abused multiple victims, I think the total number of victims was closer to 1700.
