If I was the worrying type, I would worry about the lack of comprehension of the English language;
ordinarily a review has no investigative remit whatsoever- the scale and extent of this enquiry cannot permit for such an approach. It will take too long to progress to any “action stage” if activity is given wholly and solely to a review process.
The ‘investigative review’ will be conducted with transparency, openness and thoroughness.
There seems to be an expectation dominant in all you post that nothing should ever have changed in the initial three pronged approach to analysing investigative materials from the past in the hope of progressing Madeleine McCann's case.
Signifying a very real resistance to change and thus failing to understand what Operation Grange or any other cold case review is designed to accomplish.
The most compelling outcome in Madeleine's investigation to date is the huge change brought about by advancements in knowledge led by new information and evidence which added German input to the mix.
I would say that the Operation Grange remit of attempting to discover what happened to Madeleine has been amazingly worked.
As yet we have no definitive answer as to her fate but for the first time since 2007 there is a named prime suspect in the frame which is testament to the changing climate which has been brought about by the diligence of Operation Grange personnel.
That is what it is all about. Progress and change; words which appear to be anathema to sceptics who by their nature are condemned to be stuck like flies in the aspic of their limitations and prejudices.
