Do you really need to have the impossibilty of 'proving a negative' explained to you? Or are you (yet again) simply demonstrating your disingenuousness?
Are we back to the question of why spoons from the draw weren't tested? I still haven't seen any evidence that this is standard forensic practice. Supposing that this is an important issue, I should imagine that, if the defence had wanted, they could have had the spoons tested. Don't you think though it would be very puzzling if it turned out that Raffaele's apartment was awash with Meredith's DNA? I mean, one LCN test of the knife and it comes back as a clean sample of Meredith!!! If this is just a fluke, what are the odds? How much of Raffaele, and Amanda, and the cleaning lady, and all sorts of other peoples DNA must there be all muddled together at Raffaele's in vastly greater quantity that Meredith's DNA?
My imagination really fails me to imagine a scenario where Meredith, never having been at Raffaele's, could be such a dominant DNA source on his cutlery. I mean, they got a clean hit for Meredith on the blade! If it's claimed that is just random chance, then WOW must the odds be low.
The lab (that is, Stefanoni) can produce the records which show they adhered to the protocols in question, or there results should be ignored, period.
Doubtless. In court. If they fail to do so, then it is the job of the defence to embarrass the hell out of them. Why should the lab produce the evidence for us? Dr Waterbury says he has proof that no controls were done. He is an Amanda Knox advocate, so presumably cares about proving this to the public. Let him share his proof. If he doesn't share the proof, then what are we to conclude but that he doesn't consider this an important enough issue to prove, or that releasing the data he has would be more damaging than proving this single point.
If Dr Waterbury is right, then surely he has proof that Dr Stefanoni lied on the stand about the controls? Is this mentioned in Amanda's 200+ page appeal document?
