How I agree with you, he's so messed up he's a danger to himself and those around him, especially his own kids. But he's lived for so long in a completely alien world he doesn't see what's happeneing to him.
If that documentary had been about some unknown guy from a social housing project or trailer park the police would have taken him away before the final credits rolled.
The press are still going on about it here days after it was shown and most of the opinion is that he needs to be seperated from all kids and investigated thouroughly.
But there are many out there saying "you just don't understand, he's a caring person".
Sorry, but I think I understand too much.
