I have no idea whether he's guilty or not as I think I've said a few times. I'm not interested in credibility either, I'm interested in evidence. When I see evidence that suggests he was actually rather than possibly involved I may be more interested. At the moment no such evidence has been released. It's all speculation.
Just because you have not personally seen the evidence the German authorities claim to have, does not mean it does not exist, or that it is not strong. There are plenty of things in this world that you accept as 'true', even though you have not personally seen the evidence that proves it. But you accept it, based on professional opinion of those who have seen the evidence and their reputational standing.
That's human nature. In most part, people accept the opinion of experts, especially when they have no motive to lie about their conclusions. Where people actively refuse to accept such an opinion, it is almost always because the conclusion of that opinion directly conflicts with something they already believe/want to be true. The theory of evolution among people who are devoutly religious is probably one of the most common examples of this.
Let me be clear. I am NOT saying anyone should blindly accept that CB is guilty based on say-so from the Prosecutor. It is fair to have doubts until the evidence is revealed and independently evaluated. But there is a big difference in reserving judgement and actively trying to discredit the case against CB without anything of substance to back it up.
That's what all this is about. Despite what position you might claim to have, it is actually that you don't want to believe CB is guilty, simply because you already have an opinion that the McCanns are. It's nothing to do with not seeing the evidence, or thinking that Wolters may be some loose cannon whose views don't align with the BKA investigators, or that OG are still saying "missing persons investigation", or any other weak point you've sought to sling mud at and take the thread off-topic. If Wolters/BKA were making these kind of accusations against the McCanns, you would not be making the same objections, you would be embracing them. That's the truth of it.
You are hiding behind the PJ files and your mistaken conclusion that the evidence points to the parents. It doesn't. There is NO evidence that directly implicates them. There is a lot of speculation required to devise a theory that involves the McCanns and those theories are all still lacking in credibility for one reason or another. Most commonly, they lack a plausible motive. The truth is, the overall evidence in the files supports a stranger-abduction scenario MORE than it supports any other particular theory the sceptics care to offer up.
You were right about one thing though, when you said you weren't interested in "credibility". You really should be though. Not all 'evidence' and 'opinion' is equal in veracity.
