Brückner has been travelling between Germany, Portugal, Spain and Italy. He left PdL shortly after Madeleine disappeared. I have said it before: on 2 May 2007, het told his ex that he has a horrible job to do in PdL the next day and that it will change his life and that she would not see him in the near future. The PJ is under real pressure. That is what I think. So yes, I do realise that it is not on the PJ agenda for now because they are backtracking. Amaral revealed some of this almost a year ago. German police have obviously unearthed something very significant relating to Madeleine and the PJ and Amaral do not like this.
I'm not sure what you mean by travelling between Germany, Portugal, Spain and Italy? From 1995 - 2007 he spent most of his time in Portugal with short spells in Germany. If he travelled by rail/road he would pass through Spain and most likely Italy too.
Where are you getting what he supposedly told an ex from?
Amaral is no longer part of PJ. No reason for the PJ to be uncooperative. If CB is responsible, I don't think he is, PJ will just blame it on Amaral. Portugal will just sigh with relief it wasn't one of its own and it can move on.
