Yet again if the investigation was flawed so must its conclusions be ie that the McCann’s non- involvement had been established. You can’t have it both ways.
You never know, Faith. Maybe the final lead is to identify Amaral's missing fridge after all...

Personally, I found the prosecutor's summary objective:
Even if, hypothetically, one could admit that Gerald and Kate McCann might be responsible over the child's death, it would still have to be explained how, where through, when, with what means, with the help of whom and where to they freed themselves of her body within the restricted time frame that would have been available to them to do so. Their daily routine, until the 3rd of May, had been circumscribed to the narrow borders of the 'Ocean Club' resort and to the beach that lies next to it, unknowing the surrounding terrain and, apart from the English friends that were with them on holiday there, they had no known friends or contacts in Portugal.http://www.mccannpjfiles.co.uk/PJ/LEGAL_SUMMARY.htmIt's not clear if his remark re the "margin of error" extends to Rebelo-time or not. In view of the circumstances Rebelo inherited, I found that he generally did a good job. Time constraints due to arguido status meant that he had to find evidence with which the prosecutor could charge one or more arguidos or archive the case.
I don't see how the investigation could have started from zero again with those time constraints, unless something extraordinary had popped up.
Perhaps my only (mild) criticism was to have spent seemingly ages hunting down the source of the ink to print out the photos when it would have been much easier to simply ask and verify the explanation.
