One thing at a time. The latest hearing focussed on the central so-called "evidence": the knife, the bra clasp and Curatolo's testimony. It's now clear that Curatolo was talking about Oct 31, and not Nov 1 at all, while the DNA on the knife has magically disappeared and the bra clasp has been effectively destroyed as evidence by further negligence on the part of the police "experts".
The next stage is an audit of the methods used to obtain the DNA evidence, which will confirm what the innocence side has been saying all along. It's my understanding that Amanda was also convicted of allegedly "staging" the break-in, so that will have to be addressed in due course. I fully expect that the prosecution's claims will melt away even more rapidly than the DNA and "witness" statements.
With regard to Curatolo, I think the new clarity is that he doesn't really know what he's talking about at all. I think that the appeal court will completely discount his testimony as entirely unreliable. I don't think he simply got the date wrong (i.e. I don't think he saw Knox and Sollecito over a large portion of the evening, but on 31st Oct rather than 1st Nov). I think he made the entire thing up, and I think I know why he made it up.
BTW, as I've said before, even if the alleged "staging" is never addressed in the appeal, it's still absolutely no bar to Knox's/Sollecito's acquittals. There is NOT a simple causal link between a staged break-in and Knox's/Sollecito's involvement in the murder (although many people would love to believe this to be the case). This is because even if Guede were solely responsible for the crimes (or if he committed them with others as yet unidentified), if he was let into the house by Meredith, then he clearly had a motive to pretend that the culprit was a stranger-burglar.
Imagine that Guede's standing over Meredith's body, thinking what to do next. He realises that if he simply leaves by the front door, the police will quickly conclude that Meredith knew her killer well enough to let him into the house on a night when she was there alone. He'd have easily been able to realise that very few people in Perugia would fit into this category - including him. And given that all the boys from the lower cottage were visibly away, and that many other student friends of Meredith's would also have been away that night, he'd have reasoned that the pool of potential suspects would be pretty small.
Therefore, by staging a break-in, Guede would seek to change the potential pool of suspects away from anyone Meredith actually knew, into any burglar. And that group contains an awful lot of males between 16 and 50 years old. So - even though Guede himself had form for burglary - it would actually make sense for him to fake a break in, since it would potentially lessen police attention on him.
However, all that having been said, I still think that the break-in was real, not staged, and that Guede (or possibly an accomplice of Guede) was the culprit. I am merely pointing out that there's not a strict causal link between a staged break-in and Knox's/Sollecito's involvement in the crime.
