Sadie, Sadie... give me your answer do,
I'm half crazy all for those files of blue.
We are told there is strong evidence of Madeleine's death. We haven't seen it yet and until we know what it is and accept it I think we are entitled to hope for the best that Madeleine survived. In their last official statement that's what her parents hope for too.
Amaral fed negativity into every aspect of Madeleine's case with his insistence on 'the smell of death' behind the couch - on a shelf in a cupboard - outside the patio doors - in the garden - on a cuddly toy (eventually) - on items scattered willy nilly on the floor of a public gymnasium - on a key fob and in the boot of a car. Not to mention his allusion to in transit body fluids sloshing over the front left wheel of the same vehicle.
I think that is probably worthy of ridicule were it just not so tragically wrong, giving whoever caused it over fifteen years to cover any tracks which were probably never to be found in 5A in the first instance.
