Isn’t it a given that when someone goes missing that those closest to them are investigated? So why would they be worried about that? It’s protocol.
If my child had gone missing and the police told me that if I walked down the street butt naked it would help find them, then I’d do it.
I’d tell them ANYTHING they wanted to know as I’d have nothing to hide.
I certainly wouldn’t refuse a reenactment of the nights events.
Of course it's a given that those closest are investigated when a child that goes missing - I said that the McCanns were unco-operative when they realised this - but this is not evidence that they have anything to hide.
When a child goes missing 90% of the time someone close to them is involved, so obviously the McCanns would be investigated. However that leaves 10% of parents who had absolutely nothing to do with their child going missing (beyond leaving them alone in an unlocked apartment in the McCann's case).
Regarding the parents doing a re-enactment - no legal advisor would ever suggest doing this, the police ask people they suspect of being involved in a crime to do a re-enactment as its a great way of making yourself look guilty. Of course you'd want to co-operate but you wouldn't want to end up in prison, and the perpetrator getting away with it, if you hadn't done anything.
eta - when I said 'normal' in my previous comment I meant whether it is normal behaviour to be unco-operative with a police investigation. Of course it is normal practice for the parents of a missing child to be investigated.
Just to clarify.
