Once again we can take guidance from the AG's legal summary
On the other hand, it also results that none of the parents was inside the apartment when Madeleine disappeared and that their behaviour until the moment of the disappearance was perfectly normal, not manifesting any kind of preoccupation or any other similar feeling, contrary to what happened after that moment when the state of panic was notorious.
So, we know that the McCann went through their daily routine acting exactly as they previously had, showing no signs of stress, turmoil or odd behaviour. In fact nobody has given any reason or raised any concerns about suspicious goings on with regard to the McCann or anyone else within their group of friends. Quite the opposite, they are described by staff, waiters, etc who came in contact with them over the week as a happy, carefree bunch of people enjoying their holiday.
I agree with the AG. The documented behaviour of the so called Tapas friends & the McCann is simply not consistent with the suggestion that they (as a group or individually) were in the process of covering up a major crime involving the death of one of their children.
