Sorry, your tendency to overblown exaggeration and verbosity must have rubbed off on me. I think you got the gist nonetheless and are simply unable to come up with anything approaching a logical explanation for why two guilty people would not warmly embrace the German investigation if it meant someone else went down for years for the crime they themselves committed. Saying "because of the fund" is illogical. It makes no sense. A successful conviction of a patsy could even result in MORE money coming in as my previous post mentions. And - they can misappropriate funds with a patsy in jail no problem, nothing stopping them (apart from obviously everything that's stopped them doing so in the last 17 years).
Let me ruminate on it. It's actually quite complex the more I think about it.
I will say this, some aspects of this case, some 'evidence', clues, reports, statements may seem pertinent, but won't be but may be intriguing in and of themselves. 'Red herrings' to coin Kate's phrase (even this has been picked apart - see, now I'm at it).
As with the 'plausible explanation' I just wrote on the other live thread on this dying portal, sometimes it's just coincidence. Murat, for example, for all the Tapas finger-pointing, it turns out that he's just an odd bloke who speaks the lingo, probably injected himself into it busy-body style and got bummed by Jane and Russell for his trouble. Coincidence.
