How does Operation Grange end, hypothetically? Does it implicate all those, who we who have studied this case way too intently, believe were/are involved (and who's names we dare not say out loud)? It is hard to see how they can be ruled out. If Madeleine wasn't abducted, then everything the McCanns and their supporters did that night and thereafter was fraudulent. That's pretty mindblowing, and would explain why it has taken 7 years to investigate.
The only thing to apply when reading or studying this case is logic and reasoning. As nice a person as you might be, you really need to read beyond the headlines of causes you support. You need to ensure that the money you are so generously donating, is helping real, genuine causes.
The McCanns have no intention of handing their remaining £750k or any other funds they may raise, to childrens charities. The Madeleine Fund remains a non charitable company for the benefit of one child only. Or more accurately, for the benefit of the one child's family.
Not even a magician or a founder of a crisis management agency can make that sound good.
