Brietta wrongly singled out the Algarve for criticism when it is well known that it isn't the worst region in Europe for crime. Her "high risk" claim is greatly exaggerated and is not borne out by any historical evidence. Had the McCanns exercised a modicum of savy that night, we wouldn't be here now discussing this event.
The only reason for "singling out the Algarve" is that Madeleine McCann vanished from the Algarve while on holiday there with her family.
It is my opinion concentration on her parents as opposed to concentration on intelligence perhaps leading to evidence might very well have led to her safe recovery.
Intelligence such as the possible distraction of an activated burglar alarm in Odiaxere around the time Madeleine vanished.
The burglaries which had taken place in Luz were also intelligence as was the disappearance of Joana Cipriano from her home a short distance from Luz.
In my opinion, by far the most compelling intelligence of all was in the form of the home invasions and assaults on children which had taken place in the Algarve.
The only intelligence which seemed to attract any attention at all in my opinion was the dog visit.
