Amaral has been accused of all sorts without any evidence. Perhaps because he made it difficult for the McCanns to regain their reputations. His opinion that the suspect produced by the Germans and Operation Grange was being set up as a patsy probably ensured that the evidence against him had to be definitive. At the moment that doesn't seem to have been achieved.
When is it going to penetrate that to date, Amaral has got absolutely nothing right from Calpol and dogs to false photoshopped images of Brueckner.
Neither was his propaganda war against the McCanns really anything to do with them other than a means to an end because they refused to give up on their daughter as he wished them to do.
Brueckner is prime suspect in crime against Madeleine McCann in Germany and in Britain. In Portugal he is arguido.
Unlike you I rather think that quite a lot has been achieved among which has been the total destruction of the facade which was Amaral and the vindication of Madeleine's parents whose constant presence demanded that the Amaral theories have at long last hit the dustbin which is where all disproven theories end up.
