The difference between these two opinions?
It is the contortions that Machiavelli has to go through to somehow, using probablies and global assessments of marginal and/or non-existent "evidence" shoehorn two innocents into this.
It's why his defence of Andrea Vogt is so telling. There is actually a straightforward, plaintext meaning for what Amanda Knox said, "I was there." It is validated by the context in which those three words were.... She meant she was at Raffaele's all night.
For Machiavelli.... and more importantly for someone who claims the status of a neutral, objective reporter, Andrea Vogt, they use contrived substitute meanings as well as invented dialogue that isn't there to suggest that this was some sort of code between mother and daughter that Amanda may have been signally to her mother she'd been at the cottage afterall.
What Machiavelli, and Andrea Vogt, lack is evidence. In Vogt's favour she is simply passing on the hystrionics in the courtroom when this is presented as-if Amanda meant she'd bee at the cottage....
But what Andrea does not do is this - when the very first fact finding judge, Judge Massei - the convicting judge - makes reference to it, he quotes Knox's interpretation of it then drops the matter. It turns out to be completely imaterial to the case; however, if it HAD been a confession, it would have played big, esp at the trial which convicted her......
.... what Vogt doesn't do is correct the record. She just remains silent.
And then on her blog recommends McCall's Wiki as the pre-eminent site to understand this case.
The truth is not that the two students are murderers.... but if you go into the conversation assuming that they are you end up actually having to mangle the evidence....
1) Like Vogt does in her reporting
2) Like Machiavelli does when he also tries to argue that Amanda Knox was immune to sleep deprivation
3) Like Briars tries to do when he argues that Nara and Curatolo are legitimate witnesses.
