I ignore extraneous data, like the luminol yes. Because it's indeterminate, and cannot be judiciously connected to a specific person or specific time or specific substance.
You go "well since it probably wasn't horse radish sauce, it must be Meredith's blood, and since they're vaguely in the shape of feet, they must be Amanda's." That's just plainly bad reasoning, and worse, it isn't connected to any corroborating data, such as evidence of an active cleanup or management of the crime scene in any way. Rudy Guede just walked around spreading blood and prints everywhere, and it's all there.
There's one single piece of evidence in the entire case that doesn't just self evidently collapse on an immediate first glance, which is the bra clasp DNA. It collapses on a second glance. The prosecution lost their shoe prints, so they went back to the crime scene to grab a mysteriously un-collected/self moving clasp, and Stef did her duty and turned it into evidence against Raff, then destroyed it so nobody could double check her work. It was a nice try but not enough to make the case into something it wasn't.
The defense actually has an abundance of reasonable doubt. You could dump evidence and they would still have reasonable doubt. It's enough that Guede the burglar shows up on CCTV alone, the wounds and imprint all match a single small knife, and only his forensics are time stamped to the murder, but you also have his confession to his friend that nobody he knew was with him when she was attacked. You also have the unexplained wounds on his hands he voluntarily connects to the murder weapon. You also have a witness statement saying Guede had a history of pulling a switchblade sized knife during home burglaries. And for the break-in it's enough that the climb was doable and the rock was proven to be thrown from outside, but you also have a criminal record of Guede connected to a nearly identical break-in with a difficult climb and a rock smashed window.
The prosecution has Quintavalle the lying bozo, and Curatolo the helpful serial witness junkie. The case is shooting fish in a barrel for the defense really.
Your bias is grotesque. You don't seem even real to me.
Your blindness and twisting of each element is so systematic that it requires a big effort to show all the points one by one. There might be a step by step process, but, I can see that you are unflinched by some very disturbing aspects of Hellmann's verdict, for example by its racist point. You don't seem sensitive to racial issues and you seem to not see aspects of bias that are really huge, before your eyes - someone says, it requires considerable effort to notice things that are before our eyes.
You say Guede appeared on CCTV. There is actually no evidence that he is on CCTV more than Knox is, or more than Sollecito's car. But you note Guede.
There is not even evidence beyond reasonable doubt that he was a burglar, btw, he has no precedent for burglary. There is a suspicion of link, to only one burglary. Reality is made of details.
You could have equally said - based on the same type of evidence - that Amanda Knox is the one who picks up drug dealers in series, who has precedents for drug fuelled parties dangerously running out of control and rape pranks on roommates, who used to spend 1k euros cash in excess on unknown items every months; or recall of Sollecito as the knife collector and an enthusiast of snuff movies.
These are elements of profiling, but they are not evidence. They are contextual elements, they may help understand a scenario.
They are not evidence neither for Knox, Sollecito or Guede.
You cannot "use" a precedent (or suspicion) of burglary against Guede that way, as if it was evidence that Guede committed that specific crime, alone. I caught a burglar (a girl, 16/18 yo) yesterday, as she was trying to enter my dining room, an a second girl was hiding in the garden. My city - just like Perugia - is full of burglars, but nobody rapes tortures and murders women in the house: you need specific evidence about a crime.
And one of the most obvious sets of evidence about this crime, not the only one but just one of the obvious sets of evidence, is that it was not committed by a single perpetrator.
