I see it in a completely different light. I think that it is foolish to allow a personal tragedy to be used as Talking Head Entertainment. No talking head will ever solve a crime, and I've yet to see a talking head properly research a case such that the audience is left with a clear understanding of the facts.
Regarding the father, if he was going to stage the disappearance of his son, why wouldn't he at least stage the backpack at the house to prove that his son actually got there? Why would a father that is finally going to spend some time with his son make him vanish? Is there any factual reason for the father to want to make his son vanish from the face of the earth?
Since the son actually did disappear, what staging are you talking about?
