With regards to the 'negative controls requested or not' discussion. This just reinforces the view that the forensic science laboratory procedures are of poor quality and Machiaveli does not understand the practical nature of doing this stuff. When you run an analysis the run is your result; positive controls, negative controls and your ca libration curve if your analysis requires one. As I have said before, you can no more cut out a single result, from the run than it is valid to crop a photo and present it in evidence. You can show the whole phot and a close up of a scene of interest, but giving an isolated result is just disingenuous. It implies there is something you are trying to conceal, a slight of hand. As has been argued in certain circumstances even previous runs are relevant if there might be a hang over contamination. Specifically requesting the controls should not be necessary, they are part of the result. I cannot emphasise to much that you cannot interpret the results without the full set of data, this should be automatic. If there are not the control values the result is meaningless. If you ran a test and forgot the controls, or the results of the controls are outside acceptable limits you have no result. You might as well have used a Ouija board (apparently under Italian jurisprudence equally acceptable as evidence to the court).
Thank you for your contributions, I've found them of great interest. I do have a question for you: what specifically do you suppose might be Stefanoni's reason for refusing to turn over the electronic data files?
As an aside; I think interacting with Goeffrey is pointless. It is like having discussions with believers in ID or HIV denialists. There will never be convincing scientific proof. At a fundamental level they know the truth and any supporting evidence is 'high quality' and any contradicting evidence will have a fundamental flaw.
Perhaps having 'faith' (or more accurately hope!) in the power of human reason means guys like me resemble little gerbils running around the wheel in my cage to the amusement of others, but some of us can't resist the impulse to try to see if their dis/misinformation is corrected if they might even change their minds.
