To set things a little clearer. The national average in the U.S. for children who are molested is 26%. This comes from the CDC.
Using the commission's numbers of 1,006 reported cases of kids who were molested that comes out to 0.6 percent. So let's say we triple that for all the cases not reported and you would come out to 1.8 percent of Witness kids who were molested.
If you want to calculated the number of elders who knew about molestation cases you would times 1006 by 3 = 3018, but you would have to extrapolate that some of those elders would have been the same men on different committees, so round it off to about 2,500 elders.
To be fair, and from my experience I know this is true, child molestation was not looked at the way it is now. Back in the 40's, 50's, 60's, and even the 70's child molestation was taboo and nobody talked about it or came forward with it to authorities. It wasn't until you had Donahue and Oprah bringing these types of taboo subjects in the 1980's that people started to come forward about it, so it isn't surprising that pre-1980's and 1990's nobody would have gone to authorities, and it was too shameful for the victims for anyone to know, because back then they blamed the victims in society. Child molestation and how it is handled in society as a whole has rapidly changed in the 21st Century.
I had a friend who was raped by a Catholic Priest for 10 years in the 70's and 80's! When he told his Catholic father his father punched him in the face for saying such a horrible thing about that priest. People didn't speak about those types of things. By the way, that Catholic priest was later found out to have raped about 400 boys over the coarse of his priesthood.
So this is a very hot-button subject, but you have to look at it taking into consideration many different aspects: the times they happened in, societal viewpoint that had an affect at the time, etc., etc.
If these things happened now they would be looked at differently by not only witnesses, law enforcement, but society as well. People didn't go to police when kids were molested 20, 30, 40 years ago. They just didn't. It was very rare and extremely taboo.
I'm not trying to be fair and balanced; just point out the obvious.
