Dino is an idiot dinosaur with a very poor memory.
If you are an elder and hear report of a child having been sexually abused by her father 'for a long time', how can you possibly forget the details or the person who told you about it?
I've listened to 3 elders testify, one being an ex-CO and ex-DO, and when asked specific questions about a sexual abuse victim in the congregation, a case they were in charge of, their testimony is riddled with 'I don't recall' and 'I can't remember' type remarks.
One would get the impression from their testimony that Jehovah's Witness elders have the worst memories of anybody on the face of the earth.
What they actually have are convenient memories. One thing they never forget is to use the Theocratic War Strategy, which is Watchtower's teaching that says they can lie to anybody who is not entitled to know the truth in their judgement. All is fair in Theocratic Warfare, including lying to investigators, judges, and other officials.
