Unfortunately I found, and spent a couple hours reading, a full translation of the "Sentence of the Court of Assizes of Perugia," some 397 pages long.
It is an interesting document, generated by a court which operates in a way that is totally unlike our system, in which such decisions are made by juries of postal workers, housewives, and retireees. The "jury" is comprised of professionals, mainly attorneys, who do this for a living.
For the "no evidence" crowd:
Amanda Knox's DNA was found on the murder weapon (a 31 cm knife), which had been brought back to Sollecito's apartment and cleaned. The forensic examiner concluded that the place of the DNA on the handle was not consistent with food preparation, but completely consistent with using the knife as a weapon.
Both Knox and Sollecito consistently claimed to have been together IN HIS APARTMENT from the evening of November 1 through at least 10:30 on the morning of November 2. This is disproven by several eyewitness reports. For example, they were seen by two people in the courtyard outside Knox's apartment late at night on 11/1. Also, Knox was seen purchasing unknown items from a local market at 0700 on November 2. She got the items from the part of the store where cleaning supplies were kept.
Knox's explanation of why she went back to her apartment on November 2 is totally inconsistent with the plans that they had mentioned to several people (taking along day-trip to a nearby town), and is illogical in the extreme. She had washed her hair the previous night, she had no need to "get a mop," and one does not delay starting a daytrip for at least an hour for this sort of venture.
Sollecito's DNA was found on a cut-off scrap of the victim's bloody bra. Transferrence of the DNA through anything other than his participation in the attack was totally disproven.
Knox falsely accused her employer of the crime, both orally (several times) and later confirmed in writing. Her explanation of why she did this is preposterous, and was not believed by anyone.
Knox and Sollecito staged a phony break-in of the apartment, to try to deflect attention from them to an unknown burglar. The staging was amateurish and easily seen through. Knox's statements to police at the time are inexplicable, except in light of the fact that she and Raffaelo did it. For example, she told police in the initial phone call that "nothing was stolen." There were four women living in the apartment. How could she possibly know whether some small items had been stolen from the other unlocked bedrooms, or from Kercher's room? Only one way.
Knox's actions and remarks in the time before Kercher's bedroom door was broken down by police were bizarre, untruthful, and only explainable as trying to delay the finding of Kercher's body by someone who knew it was lying there inside the room. When the door was being broken down she was still in the apartment, but as far away from the door as she could possibly be. Even after the body was discovered, she made no attempt to look inside the room.
Whoever let Guede (the main killer/rapist) into the house had a key to the front door. Amanda was the only possibility. The others with keys were out of town or dead.
The injuries and attack on Kercher could not have been done by a single person. Kercher was athletic, in good shape, trained in Karate, fully clothed, etc. Multiple attackers were necessary.
There is only one possible conclusion. Sollecito and Knox did it along with Guede.
It is impossible to say how this case would have played out in an American court. There is no "Aha!" evidence that, by itself proves what happened. But looking at all the evidence rationally, there is no other conclusion one can reach.
