Yes - it would appear that Guede's murder conviction (and it IS a murder conviction) had had a little "joint enterprise"
leger-de-main special sauce applied to it by the ever-surprising Italian criminal justice system, with the (totally unnecessary and unrequired in the adversarial system it's supposed now to be*...) "judicial truth" of the crime being that Guede was a party to the murder but did not actually stab Kercher himself. All, of course, because the prosecution knew full well that the defence (obviously) and the courts would never object to a proposition in which someone other than Guede had done the stabbing, and that therefore this would give the prosecution a clear mandate and rationale for continuing its pursuit of Knox and Sollecito as "vicious knife-wielding maniacs".......
I am pretty sure I've made this point before, but (in a different context, admittedly) I happened upon a repeat of an old episode of "Air Crash Investigation" (I believe it's called "Mayday" in North America) late last night after I got home. It was the episode dealing with the Italian disaster known as the "Ustica Massacre", in which an aircraft exploded and broke apart at altitude over the sea, with dozens killed, in around the early 80s (IIRC). The judicial investigation went on - shockingly and unnecessarily - for decades.
The Italian Government became convinced that the aircraft had been shot down (accidentally) by a French Navy ship that had been in the general area. But three separate international expert investigations showed conclusively that the aircraft had instead been brought down by a bomb placed onto the aircraft before its departure (and a bomb whose precise position on board the aircraft could even be determined with high scientific accuracy). The scientific evidence of a bomb was so accurate and reliable that the international expert reports were unequivocal and certain in their conclusions.
But..... Italy "preferred" the story of a missile discharge from a foreign navy to the story in which its own airport security had been compromised to allow a bomb to be placed onto the aircraft. So, when the Supreme Court issued its final judgement on the case, in something like 2013 or 2014, it decided that the "judicial truth" was that the aircraft had been destroyed by an inadvertant French missile strike.
One (and maybe two) well-qualified commentators to the programme remarked explicitly that if you want courts to do their jobs properly in determining responsibility, Italy is perhaps the very worst country which pretends to "first world" status in which to expect that to happen. It IMMEDIATELY brought to mind the farcical Chieffi SC panel, together of course with the Massei and Nencini courts, in the Knox/Sollecito trials process.
Thank goodness - and thank justice - for the (apparently very rare) shining examples in the Italian criminal justice system such as the Marasca SC panel and the Hellmann court.
*And we can remind ourselves again here that ALL that the Italian courts were required to decide in the Guede case - nothing more and nothing less - was simply whether there was sufficient credible, reliable evidence to constitute (in the courts' opinions) proof BARD that Guede had committed each of the crimes with which he was charged. That's all. On the murder charge, for example, all the courts needed to conclude was that there was sufficient credible, reliable evidence that Guede had been wholly party to the murder** to pronounce him guilty on that charge - there was no need whatsoever to speculate upon whether or not he'd actually stabbed Kercher, when there was ZERO evidence to show whether he had or he had not done so.
**and there
was: the combination of the bloody handprint on Kercher's pillowcase, the Skype call to Benedetti, the huge holes in Guede's story, his clea attempt to construct an alibi by going out dancing in discos mere hours after the murder (in giant contradiction with his claims to have been feeling frightened and panicked), and his flight to Germany)
