On the highlighted part, I would love to see a cite where Italy is an expert at LCN DNA. I don't believe it for one minute after watching their top people preform on this case.[/I]
That's not exactly what they're saying, it's more along the lines of 'the inquisitorial systems of Europe have been using LCN DNA to convict people for years now.' I assume, like the Italian system, their inquisitorial roots incorporate the prosecutor as an 'incorruptible' purveyor of Truth and thus allow them to introduce just about anything they want as 'evidence.' DNA seems to have 'magic' qualities about it, if the prosecutor finds DNA
anywhere for
any reason it seems to translate to 'they done it' with some people.
Unfortunately with LT DNA, for which the risks of contamination are extreme compared to high copy number DNA analysis, it is often very difficult to say where the DNA
came from. With blood, semen or saliva left at a crime scene there's at least a physical representation of what they found, notably 'So-and-so left their saliva in a bite wound;' or 'we found this blood at the crime scene attributable to so-and-so.' It
makes sense what they're saying, not so much with the LT-DNA analysis done in this case.
Here they're saying they found Meredith's DNA on a knife that tested negative for blood and didn't match the wounds, and they don't
know where it came from, that part is 'hypothesis'--but it
must be a result of Amanda wielding that knife in a death struggle with Meredith. That's where the 'magic' comes in. With Raffaele on the bra clasp the situation is similar, somehow his DNA gets on that bra clasp, and by making those same untoward assumptions instead of the question being: 'how did that DNA get on that clasp along with at least two other males,' it instead becomes 'Raffaele's DNA must be the result of him handling the clasp in the course of the murder'--or maybe its contamination, but what are the 'odds' of that again?
No matter how improbable the scenario, to some people Meredith's DNA on that knife or Raffaele's on the clasp must either be the result of the murder or contamination, and comparing it to contamination rates in labs required by outside entities to keep track of contamination leads one to the (spurious) conclusion it must be a minimal concern. However, as you've noted before with the link from New Zealand, with LT-template DNA analysis they're basically looking for contamination level DNA--and thus they're much more likely to find it, especially in labs not equipped for the stringent new protocols devised to prevent such accidental exposure.
So with these inquisitorial systems they don't have outside agencies or even their own judges in some cases determining what is valid evidence, thus they produce DNA on a zucchini, say some of the wounds are compatible with being bludgeoned by a summer squash, and presto! Conviction! It may not be a coincidence that of the EU members the
inquisitorial systems
dominate the ECHR in violations under the category 'right to a fair trial' for this and other reasons. Looking at that former chart, including EU members only, and juxtaposing the per-capita approach also offered by that excerpt from the legal tome, one is left with this list of violations under the 'right to a fair trial' category:
1. Italy 194
2. France 161
3. Britain 61
4. Greece 56
5. Austria 45
Thus Italy and France dominate by raw numbers, and the UK is present, but is more comparable to the next two, which are also inquisitorial systems. Off the top of my head, Britain must have at least five times the population of Greece and Austria, which makes their per-capita 'advantage' profound.
In the long run I don't think it will be to the advantage of either LCN DNA analysis or the inquisitorial system for it to be said now that the inquisitorial systems of Europe are 'ahead of' the United States and other countries a bit more leery of this kind of DNA analysis, the foundation of which is the fallacy of equivocation: LT-DNA is
not that same thing inherently as finding someone's blood, saliva or semen (or other truly traceable signs) and attributing it to the suspect through DNA analysis. It's the presence of the biological material that's incriminating, the DNA analysis just more properly attributes it than blood type and the like could do in the past. Trying to find criminal meaning--and
only criminal meaning--in specimens that leave no actual traces outside what can be divined by LT/LCN DNA analysis is an entirely different thing.
