They are guilty because the police nore anyone else could fabricate that set of evidence, nor it is reasonable to assume that anyone fabricated any part of it.
Everyone is entitled to their opinion. I believe you have a strong bias towards guilt that is not a conclusion from fact. I say this based on the evidence you offer:
The most obvious piece of evidence to me was:
Knox and Sollecito's lies,
the repeated false accusation including Knox's memoriales,
What you consider lies, and your assertion of a false accusation, and your view of anything Knox wrote, cannot be used as evidence of guilt because they only have meaning as evidence of guilt if she is guilty.
Please pay attention to this point: This so-called evidence of guilt is wholly dependent upon her guilt for its validity. It is not circumstantial evidence as the luminol footprints or the bathmat print might be. The evidence of what you perceive to be lies and false accusations are indirect reports about the crime, from a source you consider to be guilty. The reason you think they are lies is because you think she is guilty. You are not reasoning to the conclusion that she is guilty from this evidence. It cannot be done.
the autopsy report,
You made this assertion just a little while ago, and
when asked to say why the autopsy report led you to this belief, you instead relied on other sources to help you reconstruct a version of how the killing might have happened. This is not evidence it is conjecture.
the autopsy report does not name either Knox or Solecito. The closest you get to evidence is the assertion that more than one person had to be involved. This assertion is far from a necessary fact, no matter how unwavering you are in making it.
A typical inexperienced murderer tries to strangle the victim, but it's a lot harder than the movies make it appear ( or so I am given to understand). Victims of an inexperienced killer often have signs of both strangulation and stabbing.
the luminol footprints,
This at least is evidence. The problem of course is that Knox lived there. Her DNA should be everywhere. Finding it, even alongside of Meredith's is not surprising.
What is surprising is that the
best theory you have requires a very special thinning so that its negative for blood but still blood. This is mere conjecture. This puts that evidence in the "it could be, under a very unusal circumstance " level of validity. That is to say, weak.
the bathmat print,
This is evidence. Just not clear evidence. You choose to believe it. I choose to believe that you choose to believe it because fo your strong bias against Knox and Sollecito. The bathmat has been argued here by you and others down seemingly to the molecular level. It doesn't look like Sollecito's to me. Even the prosecution stops at compatable. What's compatable?
the staged burglary.
This is hardly a given. Many objective, experienced professionals conclude it is not staged. They could not do this if it were obviously staged. Time was when the main assertion for the staging was the difficulty of entry. Now that this assertion has been blasted out of the water, you just carry on as if it never mattered. This is one reason I think you are biased and not reasoning to the conclusion of guilt.
I also consider Capezzali and Monacchia obviously credible,
As others have pointed out, objective testing in both US and UK news shows proved a scream from Ms Kercher could not be heard. To bad for the Italian justice system that they have to rely for a fact on things everyone around the world can see via objective news reporting to be false.
Filomena
Filomena reported no fighting, hostility, or friction between Ms Kercher and Ms Knox. Filomena's testimony favors Knox's innocence.
and Anna Donnino credible as well.
How about the rest of the interrogating crew? Didn't they all sue Knox's parents ( and Knox herself?) for slander about the cuffing to the head remark, and didn't they all to a one refuse to show up in court to make the allegation before a judge?
And isn't one of them suspected of carving a phallic symbol on her ex husbands car, and slashing a psychologists tires? There someone you can count for the truth.
And isn't at least one other in trouble for looking up personal dirt on people at the behest of someone else in the department. I think two are involved with this.
Oh, these are trustworthy people alright.
