Which people were you talking about when you wrote this?
You claim these people did not co-operate by refusing to take part in a reconstitution. The only people who employed private investigators were the McCanns, ergo you must have meant them! Kate did refuse to answer police questions on one day out of many months in Portugal, Gerry co-operated fully however, but cumulatively this equates to "refusing to help the police with their enquiries" in your book.
When the forty eight questions had anything at all to do with finding Madeleine McCann they had all been answered during many hours of questioning.
When the forty eight questions were put to Madeleine's mother when she was constituted arguida without a shred of evidence to support it ... she exercised her right under the law not to answer questions which would be used to incriminate her.
Funny that it is ignored that Madeleine's father answered all the questions put to him.

September 7, 2007. Kate McCann entered the Polícia Judiciária in Portimão in the morning and the questioning extended into the evening.

Kate began by replying all the questions, but when she was made an arguida, she stopped talking.

Within the process, you were shown films of cynotechnical inspection of forensic character, where the dogs can be seen marking indications of human cadaver odour and equally human blood traces, and only of human origin, as well as all the comments that were made by the responsible expert. After the visualization, and after cadaver odour was signaled in your bedroom next to the wardrobe and behind the sofa that was pushed against the living room window,
you said that you could not explain anything apart from what you had already said?You said that you could not explain anything apart from what you had already said, concerning the marking of human blood behind the sofa by the detection dog
You said that you could not explain anything apart from what you had already said, concerning the marking of cadaver odour in the boot of the vehicle that you rented a month after the disappearance?
You said that you could not explain anything apart from what you had already said, concerning the marking of human blood in the boot of the vehicle?
You said that you could not explain anything apart from what you had already said, upon being confronted with the result of the collection of Maddie’s DNA, which was analysed by a British lab, behind the sofa and inside the vehicle’s boot?

If no guarantee could be given to people that participating in a reconstitution would not expose them to similar treatment I think it would be extraordinary if they subjected themselves to such an experience.
Just as the forty eight questions were not designed to help in the search for Madeleine neither was the reconstitution.
