Don't see any reasons why Italian police would be so keen on arresting Knox and Raffale. Wasn't Guede enough? Also, they have a lot of experience in murder cases as they fight mafia. So it is hard to understand why they made such significant technical mistakes at the crime scene - I thought that maybe on purpose? For this reason I think that X - who would be the protected one in such a case - may be some local guy. It is really a kind of Twin Peaks story.
But I don't think that X would kill without Amanda - there was no such cases in Perugia before Knox and no after Knox. So if X exists, then the prosecution of Amanda and Raffale could be a kind of X revenge that they put him in this position, of being a murderer. It essentially looks like two indictments were being pushed at the same time, one of Amanda and Raffale, and another of Guede, which also points to some divergences in police, since, for some reason, one indictment wasn't enough.

She's innocent, with the evidence it's clear that the guy from Ivory Coast did it.

The girl was whoring around in Italy but that doesn't make her a murderer.

That being said when she was younger and without herpes she's a solid WB.

The evidence only says that Guede was in a room. The evidence that he touched her comes from a pillow, but he was probably trying to move her head when she was talking to him. No victim's things were found by him, he didn't rob her. Why?
On the other hand you had this bra with Raffale's DNA. Why a bra should be less telling than a pillow?
The defense idea that the bra collected DNA from the dust sounds strange to me. It also doesn't glue with the fact that the bra was covered by other things and was found only during final search of room.

Also, just now I have noticed that she was murdered on 1 November. In Europe this is so called All Saints Day, in popular culture known as the Day of the Dead Ones. It gives a bit credibility to the suspicion that it could be intended as some kind of ritual. And it is rather clear that Amanda lived in some kind of haze at that time.

Overall Guede's story is more cohesive than Amanda & Raffale's story.
Amanda and Raffale were acquitted simply by declaring evidence against them inadmissible. Guede was not so lucky. You can understand why he is angry now.

As for the American audience insistence that it was a sexual rage murder, and this is how it is, how Negroes are, it starts to remind me a bit of "To kill a mockingbird" Harper Lee's, too .
Whatever. But clearly on different shores of Atlantic there are different ideas about this crime. We are still tribal, or our cultures are different.

Maybe the story is not yet closed. In Europe there is no double jeopardy law, so if new evidence is found, they can roll out a new trial.
