Since the burden of proof is on them, if they have not produced any children, and are apparently hanging their hats on 30 year old cases, then they have not met their burden. It is not the responsibility nor obligation of the organization to produce anything to dispel unproven claims.
This is even more a problem for them if the abusers weren’t even jws, or if the abuse took place in their homes. We know the vast majority of child abuse is perpetrated by relatives, and trusted friends and family, and in the home.
Since jws have literally no programs that inherently put children under the care of the organization, or under the care of non-related adults, the opportunity to abuse while involved in an organization-sponsored activity is slim to none. During the meetings/assemblies/conventions, families sit together.
This is why no one in the 140 year history of jws have been able to legitimately prosecute in court, the organization as an organization, for their alleged coverups.
Its simply not set up in anyway that separates children from parents.
These truths will come to light if an investigation is honest, and transparent.
