Let's make clear a couple points.
To me, there is no reasonable doubt Amanda is guilty. She is guilty, not "maybe guilty". I think there is sufficient information to determine Amanda Knox and Raffaele Sollecito are guilty. I think guilt can be argumented and maintained rationally, but I would argue of it only with neutral interlocutiors.
Second, i will never agree on an argument baset on letting go one person. If one person walks free on arguments based on concepts of absolute demonstration, then all people convicted on circumstantial evidence and testimonies have to go free. The basic requirement of justice is equality: what society can afford, the public sense of justice and security, must be assessed considering that all defendants who have the same kind of evidence against them have to walk free.
Third: justice is not between one individual and society, surely not only that. It is so in the common law US system. In Italy, justice is something partly private: it is between two families. The Kerchers must have justice, not the rest of society. The culprits have to owe them their belongings and must comply to their terms.
Wow! No wonder everybody has picked up on your replies! I would argue with everything you've said. However, others have started those discussions while I slept. So I will just question you about your second point - especially the highlighted statement
must be assessed considering that all defendants who have the same kind of evidence against them have to walk free.
I cannot quite understand why you think Guede must walk because the information against him is of the "same kind". How is the evidence and case against Guede in anyway similar?
The only similarities between Guede and the other two are that:
1) Guede broke into the house in which AK lived.
2) Guede said he liked Amanda.
3) They were accused of conspiring together.
4) They both have, in the past, used knives.
5) They're both spending time in jail for the same murder.
6) They were both part of Massei's ficticious conspiracy theory.
7) They both have frequented the same pub.
8) They've both walked the same streets.
9) For a week, they've both lived in Perugia.
How do you 'conclude' that "all defendants who have the same kind of evidence against them have to walk free?" The implication you make is that because Guede has the same evidence against him as there is against AK and RS that Guede has to go free.
Are you related to Guede? Are you his lawyer?
What
evidence is the same kind?
How does the 'same kind' of evidence get perverted into being the same evidence? Most evidence is of the same type. Finger prints & DNA are two types of evidence. That doesn't imply that the evidence is the 'same'. It's not even close.
