As Orphan Crow clearly stated, the ongoing and biggest problem and source of liability is WT keeping these matters hidden and not involving proper authorities.
WT dictate to all JWs, to keep matters within the cong and not involve 'the world'. WT then instruct elders to contact WT legal depart for further instructions when matters of sexual abuse are reported to them.
Although WT claim that child sexual abuse is to be reported to authorities where required by law, the Australian RC has shown that doesn't actually occur as 0 of the approx 1600 cases involving over 1000 perpetrators was never reported. Australia does have a few mandatory reporting areas so it can be assumed that at least 1 incident occurred in one of those areas.
As each incident is not reported to authorities for proper investigation and as those reporting the matter to elders are often threatened against talking about it to others, the perpetrator continues to be unrestricted from repeating similar behavior with other children within or outside the congregation.
Congregants need to be encouraged to report matters directly to authorities but if they choose to first report to elders, elders need to then contact the authorities directly, not first reporting to WT legal dept.
For an organization which claims its members have the highest morals and respect for the law in a Christ like manner in representation of the one true God, most people would assume they would be a shining example of how these matters are to be correctly handled. Instead, WT has been shown as one of the poorest examples on the planet and they continually oppose being forced to fix the situation.
