As for Phizzy's question about what the JWs might discover: I think it was the Australia commission that found a record of complaints/reports of CSA against more than 1,000 JWs. I believe that this was during a period a bit shorter than the 1940s to present. I don't think the numbers can be compared directly, but it's still a staggering total.
