What exactly is the sequence of events after Madeleine's disappearance?
Margaret Hall reported the event she experienced to the police.
The police put her in touch with metodo3 who were working for Madeleine's parents.
They took her statement and relayed it to the Portuguese.
The Portuguese police ruled it out of the investigation because it was not considered of relevance.
What is right and what is wrong with that?
In my book,
- It is right that Margaret reported it to the Police
X It is wrong that the Police ignored it, but I am glad they passed it on to Metodo, because otherwise we might never have heard about it.
- It is unusual that Metodo had to take the statement from Margaret, that should have been the Polices job ... but good that they passed the statement on to the Police.
X It is bad that they ruled it out of their investigation, because they say they did not consider it of relevance
Presumably it was considered of NO relevance because it went against Amarals almost immediate thesis that Madeleine died in 5A. He was set in that thesis and didn't want anything indicating or proving it wrong, IMO
So analysing it:
The right things were done by Metodo and the wrong things were done by the Portuguese Police under Amarals command.
Poor Madeleine, she was badly let down by Amarals fixation that she died in 5A. IMHO
