That's the conclusion I came to just before I left JWs 8 years ago. I couldn't understand why they didn't take steps to protect children unless they themselves were pedophiles.
I had a civics teacher back in high school who told us that legislators enact lighter punishment for offences they themselves are more likely to commit. Drunk driving was the big one back then - a mere slap on the wrist. (In the intervening years things have changed, thanks to grass roots campaigns like MADD.)
That little lesson came back to me when I first learned of the pedophilia in the organization, and the only conclusion I could come to was what you posit in your video, Punky.
