Thanks for walking through all these points above.
Don't want to sound repetitive, but I think the emphasis of the evidentiary value of a finding of Meredith's DNA on Raf's kitchen knife is way overblown, when the physical context of the crime scene only permits a single attacker.
There is zero physical evidence of anyone but Guede attacking Meredith, and a dubious DNA result on the knife, even if the DNA reading had been valid, would still not be "incriminating" evidence, imo.
Also, other posters have questioned the validity of evidence collected against Rudy at the same time as the bra clasp 6 weeks after the crime. Some have asked, or claimed, that such evidence had no merit because it was also contaminated - by not having been collected, and/or being mixed into the hamper.
I agree the poor collection method adds to the possibility of contamination, but finding Rudy's fingerprints on the jacket are not in dispute. And finding Rudy's DNA is supported by that physical fact. The point is, though the evidence collection isn't perfect, that fact alone ought not preclude the evidence from consideration at trial, though it certainly can be questioned, imo.
In short, the findings are not conclusive simply because they exist, and the only question left is whether the findings are correctly validated. But rather, the question is firstly whether the findings are valid, and then secondly, so what? What is the meaning of the findings, even if true?
The absence of any other evidence of Amanda and Raf, while taken in conjunction with not only evidence against Only Rudy Guede, but the impossibility of anyone else participating and not leaving similar evidence, makes the exercise of the knife and bra-clasp something of a fools errand, IUAM.
This is what I have said many times - the discredited DNA results would not indicate guilt even if genuine. Mach, Vixen and the other faith-based posters are fond of claiming "there is no innocent explanation!" but this is another of their deluded claims.
Not only are there plenty of ways that the DNA could have been present on the knife and the bra clasp before the crime occurred, but there are no plausible ways in which the 2 traces could have got there in the course of the crime. So we have Massei having to make up a fictional, evidence-free account in which Amanda allegedly carried the knife for "protection", while we have others claiming that Raff allegedly forced the tiny bra hook open with his fingers - rather than unhooking it in the normal way without ever touching the hooks.
Of course, this kind of reasoning isn't unique to Italy. In the Birmingham (UK) pub bombing case, alleged traces of explosive on the hands of the accused were taken as "evidence" they had planted the bomb (rather than manufacturing it); in the Lockerbie case, highly suspect identification evidence of Megrahi allegedly buying the clothes, was taken as proof that he had planted the bomb; and in a case I know of in the US, an alleged rapist-arsonist was convicted partly on the claimed discovery of fire-damaged items from the house in his car (showing that the items were taken from the house after the fire, at a time when only the police had access to it).
