To the part I have bolded - no the evidence and information does not remain the same. It is very different indeed.
For example, the checking routine influences what went on not to a minor extent but to a major extent.
For example, the state of the children's bedroom influences what went on to a major extent.
For example, the McCann phone calls that night influence what went on to a major extent.
And answers are not likely to turn up soon if the remit says abduction.
Of course the evidence that came into their possession never changed. IIRC SY had over 40,000 documents - from various sources - the
contents of which remained the same whatever the remit was. SY's intention was to go back to the beginning. AFAIK it was not in their remit to exclude or ignore information provided by the McCanns and their friends from their investigations.
The idea that SY could carry out a proper investigation whilst excluding the input of the McCanns and their friends is totally unrealistic IMO. (if that is what you are claiming).
My question remains the same. What would SY do with information that may have emerged from those 40,000 plus documents which clearly suggested that the McCanns were implicated in their daughter's disappearance?
The idea that because of their remit they would not follow up such evidence is preposterous IMO - unless one believes they were part of a massive conspiracy to protect the McCanns at all costs - which is even more preposterous IMO.
