Oh Dear, how very sad that you should so despise someone who is trying to help in whatever way he can.
His suggestions of what may have happened to Madeleine and where she might be are not at all beyond the realms of possibility. It has happened before and will no doubt happen again.
And I find it to be extremely offensive that you should decide that he he doesn't care because he is too dense.
I wouldn't mind betting that he is a tad more knowledgable than you.
His opinion is an informed one given his line of work where he honed his expertise over a period of years.
Added to that he has first hand experience of working to find Madeleine in the Algarve.
I am a bit lost on the criticism that the only files he had access to were those shown to him by Kate McCann. As I understand it the complete files Kate McCann had were professionally translated and contained the full conclusion of the PJ files on Madeleine's case up to the forensic conclusions of the time and the shelving.
The files Amaral allegedly used for his book were no doubt mainly written by him as case coordinator and were incomplete as he had no access to the continuation of the case after being dismissed from it.
Amaral's display of ignorance is the embarrassment.
As is the need to denigrate anyone who voices the merest encouraging opinion on Madeleine McCann's behalf.
