If we don't know why or what happened, why post what was said on this forum?
As a matter of fact, Amaral didn't know what happened so his theory is fiction yet you debate it.
Opinion or theory that is the question.
Sr Amaral was part of an investigating team, who had access to the bigger picture- that team concluded that there was no abduction via the jemmied, whooshing window as per information supplied by the mother. IE the team thought the parents were lying. It does not do any harm to find out why they would come to that conclusion, reading the statements and many little icky tricky bits of information which do not make any sense or are conflicting are worth looking at.
I have never claimed to know that happened to MBM, therefore I am not on anyone's side as you put it. I am interested in a couple of theories discussed with friends. I don't need to defend Amaral and his theory anymore than I would the McCanns version of events. That makes me neutral.
