Yes and the problem is that after SY realised that first open-carrying sighting was irrelevant, instead of saying "hang on, that is a stupid method anyway, why assume the perp is so stupid, let's look at other methods and timescales", they instead just switched to another open-carrying sighting, equally unlikely to be relevant IMO.
It is my opinion that the sighting of a child being carried in the immediate vicinity of an apartment from which it was soon to be discovered a child was missing is highly relevant. Particularly as it was reported to the investigating authorities at the earliest opportunity after the event.
The direction being taken by the carrier would appear to have been worthy of close investigation ~ perhaps the distraction of Robert Murat's undoubtedly odd behaviour became a sticking point for investigation beyond the confines of Casa Liliana.
The investigation as a whole seems to me to have been very insular and inward looking. What was the problem about casting the net and broadening the search for Madeleine beyond the confines of the Murat and McCann residences?
