Some people really shouldn't be let out on the internet on their own.
A tragedy caused to a large extent by negligence.
The witch hunt on the parents is disgusting.
Sentence two you accept that Maddie's disappearance was as a result of negligence. I totally agree. Any parent that leaves a young (already scared) child on their own to go out on the lash is certainly negligent.
But then in sentence three you are disgusted that the parents are being hounded...for their negligence.
I do believe that Maddie's parents have avoided sanctions from social services because of their class and that they were professionals. Compare and contrast the publicity regarding Ben Needham's disappearance. A tiny fraction of the money spent on the investigation into Ben's disappearance than has been spent, and is continuing to be spent, looking for Maddie.
I really hope that the current enquiries do reveal what happened to the poor girl but society should be as equally concerned about establishing what happened to Ben.
