The "misunderstanding" wasn't reported in the available files, was it?
The McCanns were not officially questioned between 10th May & 5th September & there is no record of what discussions took place between them & the PJ during that period. RM made 3 statements during that period yet the question of familiarity doesn't appear to have been asked by the PJ - despite the fact he was under suspicion of abduction. Wasn't that remiss, if motive was part of the process, or were the PJ working only on the theory of collusion by investigating his movements & contacts?
Why would a 'misunderstanding' be reported in the files? BTW what do you think the McCann's lawyer meant by a 'misunderstanding' ?
You seem to be suggesting a conspiracy theory existed wherein the PJ were desperately trying to link GM and RM yet apart from a question from a journalist at a press conference you have offered absolutely no evidence to back it up. We have nothing in the files, no questions to either the McCanns or Murat about each other, no paperwork to suggest that the PJ had probed the idea. In fact it is obvious from the Murat/ Tapas standoff that the PJ knew full well that none of the holiday party knew Murat before the 3rd of May.
