My opinion has changed as the prosecutions evidence was reviewed piece by piece and overtime the inability for a motive and setup of the crime was never presented well by the prosecution.
I agree, there's not enough for a guilt vote.
However, I am curious what exactly the Judge Hellman is going to do with the knife? What is he expected to do? Will he instruct the jurors to ignore the knife? How will the results from the new experts be implemented in this trial?
An excellent example of DNA chart reading and basic threshold settings, are presented here at this link. Figure 9

the knife dna chart- (note the range is set to 0 to 84 , nit 0 to 2000)

The Italian criminal justice system is different from the US or UK one. Hellmann is not only the lead judge (making rulings and running the trial) - hes also a member of the judicial panel, together with one other professional judge and six lay judges (members of the public). In other words, Hellmann himself is a juror.
Regarding the knife, my view is that the independent report will say that it's unusable as evidence in and of itself: the presence of Knox's DNA on the handle is not probative, and the alleged presence of Meredith's DNA on the blade was not identified using recognised protocols for DNA of such miniscule amounts. It will also point to significant failings in the chain of custody of the knife (most notably the transfer of the knife at the police HQ from a sealed envelope into a non-sterile box that previously contained a desk diary).
I also think that the report will make the following observation concerning the bra clasp: it may find that there is evidence of Sollecito's DNA upon it, but I think that it will find that the manner in which the clasp was left in the cottage is such a serious breach of protocol that the presence of Sollecito's DNA cannot show that it was deposited there during the crime. The report will point to the other unidentified female profiles on the clasp as further evidence of contamination: this DNA could not have survived a machine wash, for example, so it had to have been deposited onto the clasp at some time after the bra was last washed. There appears to be no logical reason why unidentified females would have been touching Meredith's bra clasp before her death - the logical conclusion is that this DNA was somehow deposited on the clasp through contamination after the murder.
