The thing is it is not up to elders (or at least it isn't the law everywhere) to report a crime such as child molestation to the authorities unless they have personally been a witness to it, or have been specifically asked to do so by the victim and/or parents who will then have to accompany them. It is up to the victim or victim and/or parents. They are the ones who have to do the reporting.
What is legal/illegal and what is right and/or moral are often very different things.
The WTBTS/JWs assert that they are the most righteous people on Earth because they worship Jehovah. If that is true, then their practices should always--AND I MEAN ALWAYS--be superior to human laws.
And yet clearly they are not.
This is conclusive evidence that the policies and practices of JWs are NOT informed by the creator of the Universe.
End of story.
It's really not that difficult a problem if one isn't married to the idea that JWs "have the Truth" to the exclusion of all other people.
Let's review: It's a cult!
