the assertion she allegedly made was reasonable as far as know...the majority of child abductions involve custody disputes....what is wrong is to use that figure to try and suggest guilt on specific parents
She asked an important question, clearing the ground beneath your feet, as the expression was. She got an answer and later that answer appeared to be 100% correct Gerry is Madeleine's biological father so you can rule out one of the major causes of young child abductions - the actions of the biological father.
It was the reaction of the 3 persons that she spoke to that she found was aggressive. It was their reaction that sparked suspicion.
"She first found them aggressive and their reaction after she showed Madeleine's parents her credentials, also seemed strange to her. Afterwards she was informed that there were no signs of a break-in in the apartment. Knowing that they are doctors she found it absolutely abnormal that they left their children alone at home. Associating all of this with her professional experience, which tells her that in 99.99 % of missing children cases, the parents or other family members are involved, she felt it was her duty to inform the police of this."
She had ruled out break in. The McCanns were tending to say the doors were locked in the first instance, but only later admitted the patio door was unlocked. But we have extensively looked at the front door, and it was only locked from the outside. It could still be opened from the inside.
She found it "absolutely abnormal that they left their children alone at home". I think most of the UK still struggle with that. How she "associated all of this" is the issue for even I can't make sense out of it yet.
