How could they move on when their investigation revealed a wholly inconsistent timescale from those most closely involved with the missing girl from 17:00 that afternoon. There was no evidence for abduction. Totman had come forward to the PJ, remember. There was some suspicion of staging at he scene.
I believe that there was a mindset in place from the early stages that entrapped the Portuguese police into making so many elementary mistakes of which some are repeated in your posts.
Developments which have taken place in Madeleine's case since that early period of errors should have made repetition of the opinion of " A badly told Story" a complete embarrassment much as summed up by Ian Horrocks in his expert opinion.
SnipAlthough theories are of course a significant part of detective work, they should be based on evidence and not simply that you think you know what happened.
The vital point is to keep an open mind and to go where the evidence leads, not where you think you want it to go.
The reality is that in such cases it is fundamental that the investigators keep an open mind and work to the evidence not what they think may have happened.
Also, their belief should be that they are looking for a live child and not confirmation of death.
This mindset is fundamental to the way an investigation progresses and how the people working on it respond to information.
