Very nearly to ten years since this very tragic incident happened. I have a lot of professional respect for Mark Williams-Thomas, he did finally shine a light into the dark crimes that Savile committed. It is no surprise that the McCanns have spoken out against him following his opinion that she wandered out of the holiday apartment. That's all it is though, an opinion just like everyone else because actual facts are very hard to come by.
It's as good a theory as some of the others I have seen over the last ten years, some of them have been absolute shockers. The one fact that everyone tends to agree on is that she vanished from the apartment, with apparent no trace.
Having said that, the Scotland Yard investigation which is due to end in March of this year are in the best position to have working theories as they are in collection of all the possible leads and facts. They are still working on the theory that she was abducted to order which was a theory that surfaced very early on in the investigation but lost an incredible amount of credibility following the publication of an intelligence report that included the carpet bombing of Belgium. Prior to Shrimpton's little addition, the theory of organised abduction did hold water.
It's still a theory that from my perspective is conducive and far more believable. However as with all the theories, lacks any concrete evidence to back it up. It is not outside the realms of possibility that aspects of that fateful evening have been misleading.
The case remains very tragic. In ten years, we are no nearer to finding out what happened to Madeleine than we were seven days after she went missing. I think Mark Williams-Thomas' opinion should be considered of value. He has shown in the past to be meticulous with investigating, an example being the Savile exposure and although there is nothing to investigate as such in the Madeleine case, he can draw on experience and research.
