Heavens, you really are so deep in denial I bet you couldn't even bring yourself to answer the questions I asked you even in your own head. It is very clear to anyone with an ounce of common sense that the PJ are supporting the German investigation (albeit in their own, sweet, plodding obstructive way), the Germans have said as much and if I'm not very mistaken so have the PJ, quite recently - don't ask for a cite, but it's on here somewhere. And of course there is the little matter of the PJ having made Bruckner an arguido, which I'm sure means they're not investigating abduction - at all, no sirree.... 
The PJ made Murat an arguido, the PJ made the McCanns arguidos, the PJ had the three amigos back in 2014 that SY had nailed on to have abducted and killed Madeleine arguidos, then around December 2014 there was another passel of arguidos made it was reported, the sum total of that, feck all, just as it is now. CB could well be an important witness to the events of 3/05/2007 if he was around that night, although Wolters is on record on ch5 telling the world CB cannot be placed in Luz that night, so thats why he's bang to rights over the abduction, not.
