I'm not convinced of this couple's 'innocence'.
I know the area/resort that Madeleine was taken. We used to frequent a bar called Chaplins further down the road. It isn't/wasn't as easy to keep an eye on things from where they were as the Mccanns make out - I mean, they didn't see her being 'taken', did they? Other matters such as sedating the children, blood found in the hire car boot, her favourite toy being washed and Kate's own words when they found the child had gone 'she's been taken, somebody's taken her' seems odd to me. My first thought would have been that she'd woken up and come looking for us, not that she'd been taken. As does it being Madeleine that was taken, and not one of the younger children. A child that age would be hard to keep quiet, she would be asking for her mum and making lots of fuss.
