Amaral was taken off of the case. Who knows what would have happened if he had been allowed to bring the Smiths back to PDL, the reconstruction had taken place etc, etc, etc.
Pity he didn't take the opportunity to have a reconstruction when the majority of the players were still in PDL, might even have managed to catch a few holidaymakers who were eye witnesses.
Then he would have to have had the airport closed to do that???
What could Mr Smith add to anything?
He was aware that his identification of Dr Gerry McCann was mistaken ... exactly as the McClusky identification of the same event was mistaken.
Unless Dr Amaral was prepared to formulate a new theory based on the information available to him he would have been unable to progress the case any further than he did.
As far as we are led to believe the current investigation is taking place because the PJ and the Met used information available to Dr Amaral in 2007 ~ but ignored by him because he had become convinced of Madeleine's parents' guilt.
