Yes Mike: you're missing the (amusing and rather telling) fact that Vixen posted something that was a) diametrically opposite to the "argument" she was trying to make, and b) not even remotely relevant to the issue at hand anyhow.
C&V were experts appointed by the court, for the purposes of assessing the forensic evidence in this case and producing a report for the court on their opinion of the quality, reliability, credibility and probative value of that evidence. They were not prosecution witnesses. They were not defence witnesses.
If C&V were (allegedly) seen in *gasp* the same bar/cafe in Perugia as defence lawyers, this IN NO WAY impugns their authority or credibility. If there were any evidence that defence lawyers had attempted to influence the C&V report in any improper way*, then there would be something to investigate. But of course there's not the slightest reason to suppose that this might ever have happened.
On the other hand, Mignini was by all accounts rather fond of meeting with the fragrant Nadeau and Vogt (and other journalists), and feeding them juicy pieces of information which *surprise* found their way immediately into the media in Italy and in other countries. Most bar associations would take a very very dim view of a prosecutor or a magistrate (Mignini was both) using the media in such an extra-judicial way to circumvent the proper court process and to get selective information into the public domain.
* And, incidentally, the provision of independent expert testimony and published information on things such as internationally-agreed standards and protocols would NOT count as improper input.....
