Doesn't seem that serious, especially if you consider that luminol prints were analyzed at the presence of Prof. Potenza and SALs were accessible throughout the investigation, and if you consider that TMB test is irrelevant. Also, you should consider that Stefanoni pointed out that they made a "series of other tests" on luminol stains at the beginning of her 2008 testimony.
.
They are just recorded as tested in a table, without any specification. But this is still irrelevant since they were tested at the presence of defence experts and magistrate. Prof. Potenza was there and could see and record exacly what was done.
.
This is a repetition of the above point. Prof. Potenza was there and he knew everything, the investigation judge was there, defence experts were summoned, the defences did not object. The omission of QBit fluorimeter from documentation cannot serve any malicious purpose, since we know the fluorimeter is less performative than the other techniques, and the defence expert of Sollecito knew the fluorineter was being employed.
- Samples marked as ‘cat blood’ were positive for human DNA[/
I don't see how you can see anything criminal I'm this. The samples were also positive to cat antibodies. They were taken from a bed sheet of a human, but yet the presence of human DNA is not certain. There was a testimony that there was a wounded cat. Now, these are questionable aspects of the investigation maybe, but I can't see something like a criminal intent.
Under suspicion of no offence. There is no elements for suspicion.
The above ones look like just complaints about documental imprecision or incompleteness, or (as for the cat) a criticism about investigation choices.
So just to be clear - are you saying that there is no question of non-disclosure here because the items omitted by Stefanoni from her report were known to the defence by other means - that Potenza knew about them, could inform the defence attorneys and that Stefanoni was able to be comprehensively cross examined on these points immediately she began her testimony?
Separately, can you cite one case either in Italy (you claim to know about the Italian legal environment), or elsewhere, where it has been known to the court that a luminol positive reaction has been followed by a TMB negative reaction and yet a conviction has been based in part or in whole on fact finding (in Italy) where the conclusion is a finding of blood in the samples or by jury verdict in common law systems?
Additionally, can you cite one academic paper or alternatively expert testimony where by experimentation or by some other reference, a bona fide, relevantly qualified scientist has stated that it is safe to conclude blood presence from a luminol positive/TMB negative test?
Furthermore, can you cite any study, forensic handbook or other literature which supports your contention that a TMB or some other equivalent second field test is an unnecessary test when the samples concerned are not submitted for confirmatory testing?
Do you agree that it is routine practice at crime scenes to follow up a luminol positive test with a second presumptive field test (TMB O Tolidine etc) and then only to proceed to confirmatory testing where the second test is positive for blood?
In what circumstances would you accept that a luminol positive reaction is not proof of blood?
