1. The fact that other alleles are found on the clasp cannot be a logical reason from which one could infer anything about the way Sollecito's DNA was on it. This is because of what Halkides called "the first axiom of DNA science": nothing about date and means of transfer of the DNA can be inferred from the presence of the DNA itself.
The extra alleles themselves do not tell anything about the way they have come on the item, and they cannot provide any information about how Sollecito's DNA came on it. Absolutely zero.
2. C&V cannot "rule" anything, while Hellmann's decision was definitively ruled illogical and null.
3. The external side of the door seems to be the area of interst (of speculation) by the defence. However the fact that Sollecito tried to kick down the door (allegedly "tried") itself may not provide a reasonable probability that a massive amount of Sollecito's DNA would stick on the external side of the door - or that any amount of it would.
I assume Sollecito did not spent time licking areas of the door surface.
In fact the problem is about the intrinsic extreme improbability of tertiary transfer, which is something that calls into play conditions that are intrinsically improbable: according to experiments requires conditions of presence of wet biological fluids or wet surface and only happens within the framework of a structured interaction between very small areas, of which one already has an abundant DNA presence - it could be detected sometimes only in cases where you already know that there has been a contact with some speific very small (square centimeters) area where it was already known there was DNA, under wet conditions, and in those extreme low probability conditions it still happens in a minority of cases.
In this case we don't even know if there was Sollecito's DNA on the external surface of the door, there is no reason to assume that there had to be DNA on the door, to think that the forensic's glove ever touched the door (which had been disassembled by that day btw), even less we have a reason to expect that this immaginary touch would have occurred on that specific square centimeter where Sollecito had left his hypothetical DNA, and even less we could assume that the hypothetical biological material in those conditions after 46 days could be "wet" that is in transferable conditions.
There is also no reason to expect this kind of alleged contamination with any degree of frequency, given if this type of transfer was frequent we should have found quite a number of other instances, not only of Sollecito around the apartment but also of Amanda Knox inside the murder room.
4. The SC anyway cannot assess this topic. They have no legal power and no mean to do it. Direct assessment of this matter is exclusive competence of courts of merits.
Let's not forget, anyway, that the bra claps is only a piece of circumstantial evidence. Sollecito had a number of other pieces of evidence against him, and evidence has to be assessed altogether.
And also, consider that the evidence against Knox adds itself to the evidence against Sollecito.
Nencini is absolutely correct. The (alleged) TMB negatives itself do not reduce at all the probabilities that luminol traces are blood, due to the properties of TMB and luminol (there is no known alternative substance that reacts to luminol but not to TMB, even less a plausible substance, they have the same false positives while luminol is more sensitive and more specific than TMB).
There is in fact no plausible alternative substance at all to explain the bare feet prints, no plausible alternative dynamic, and there are even other bare foot prints on the scene that are proven to be in diluted blood and to be related to the murder (but not showing to be related to Rudy Guede).
1. Very true, but they were there and that means they got there either through direct contact or secondary or tertiary transfer. Since it's unlikely that Meredith had sexual relations with 2-3 different men since last washing her bra we can assume it got there through transfer and that raises the possibility of contamination.
2. Playing word games? C&V concluded the results were unreliable. Hellmann's decision (sorry, opinion) was shared by M/B, and that was not only a ruling, but a final ruling.
3. Obviously you've not read up on secondary or tertiary transfer and what are good sources of human DNA. The amount of DNA transfered by touch dramatically increases as one perspires. Given a state of emotional alarm and physical exertion it is reasonable to theorize a signifiant amount of DNA was deposited on the door/frame/handle. There are several studies that show tertiary transfer is indeed possible entirely through touch DNA. You can try to diminish all you want what these studies have shown, but given that it has been proven possible it is not possible for you or anyone else to argue it couldn't have happened. But all of this is moot. Your entire argument is to turn the burden of proof upside down. There are acceptable protocols for the collection, storing, testing and interpreting DNA evidence and when those protocols aren't followed the results MUST be considered unreliable.
4. Apparently they can and did, as did the 1st Chambers SC, albeit with a different conclusion.
What other evidence against Sollecito? And while I won't get into the sheer lack of evidence against Knox, on what basis can you claim evidence specific to Knox has bearing on the totality of evidence against Sollecito?
See, this is a clear indication of the absurdity of your 'logic'. A negative TMB result is, for the most part, considered definfitive proof of the absence of blood. Even Stefanoni agrees on this point. That you think it "do not reduce at all the probabilities that the Luminol traces are blood" is (with all due respect, and I mean that...) blindly ignorant. Whether you think you can explain away the results, the results absolutely are very significant. But this is irrelevant. You continue to try to flip the burden of proof onto the defense. Luminol is a presumptive test, nothing more. It PROVES nothing. This is a scientific FACT. It is well documented that Luminol alerts an investigator to the possible presence of blood, but that a confirmatory test must be conducted to prove it. Further, even if it were proven to be blood (and let's assume proven to be human blood and not, say, cat blood) you still need to prove whose it is. So while you can embarrass yourself by trying to ignore the TMB results, you still have to deal with the fact that several of the samples had either no DNA or only Amanda's DNA. So how does that figure into your insistance that the traces were made with Meredith's blood?
