What an extraordinary post.
Quite obviously things happened behind the scenes … that is how police investigations work ... they only publicise what they need to.
I don’t understand why you think no-one had access to evidence and went into this blind.
Do you think that because Leceistershire Police were not invited to join into either the Scoping exercise or the review leading on from it, would not be obliged to pass on any relevant information they may have had?
Do you think the McCanns did not hand over the evidence collected by their Private Investigators? they were after all desperate to have a case opened on Madeleine.
Do you think they didn’t bother to read the available PJ files in their entirety?
They may have read Cristovao's book or even Amaral's book for all you may know.
I don't think any of that was examined until after the review was begun around 12 May 2011.
On 14 December 2011, it is revealed that Scotland Yard detectives had visited the Barcelona HQ of Metodo 3 - the detective agency employed by the McCanns in 2007 - the previous day. It is reported that they took away 30 boxes of documents compiled by the private detectives.

A Yard spokesman declined to say who would be interviewed and when. “We are not going into that level of details,” he said. “We are not at the stage of speaking to individuals yet. We are laying the groundwork.”
As to the McCanns eagerness to hand evidence over, OG had a hiccup there when they approached Henri Exton asking for Oakley's report;
He claimed the legal threat had prevented him from handing over the report to Scotland Yard’s fresh investigation, until detectives had obtained written permission from the fund.
