Remember the good old days when all you had to do was drown someone to see if they were a witch or not.
Now you got all kinds of science (DNA is part of science, right?) getting in the way of all that drowning.
Like it or not Mach, scientific research IS part of the legal process, always has been and always will be.
You've got the science of fingerprinting, ballistics, fiber analysis, and even the science of human physiology when you do an autopsy or take someone's temp to see when they died. Even digestion is part of that scientific menagerie.
And as a result, the trial is a kind of peer review of all the forensic science used to convict someone, and when you don't allow full disclosure of the evidence so this peer review can be accomplished, all you are really doing is going back to drowning someone to see if they're a witch,

Scientific research can be part of a trial.
It means that methods developed though scientific knowledge can be employed of the process of evidence finding in a court.
But a trial does equate to scientific research nor to results of a scientific research.
I hope this subtlety is not too difficult to grasp, because it's a fundamental difference. It's something the pro-Knoxes seems have problems to understand.
Trial and scientific methods of investigation are not the same thing.
Methods used as scientific means for evidence findings are subjected to peer review, but the trial is not something peer-reviewed nor a peer-review process, and a peer-review process about methd is not a trial.
An assessment about the quality of scientific methods that were employed to find evidence, does not equate to putting in discussion the result of a trial.
In some peculiar cases, in theory, there might be an evidence finding obtained through scientific methods that allowes the entire trial to be re-opened and its outcome to be put in discussion; but that's another story. A simple criticism or peer-reviewing of the quality of some investigation methods does not change anything and has nothing to do with the outcome of a trial.
To complain that some collecting of evidence - ballistics, fingerprint or else - used imperfect or low quality, less than state-of-the art methods, or that something is not perfectly scientific, is a completely pointless argument.
And this is true especially in this case in particular (a case based on circumstantial evidence).
You once asked me what is the difference between some piece of "scientific evidence" and the "context". To understand how scientific research, scientific certainty their peer-review on one side, they do not equate with the outcome deduced from the evidence under a legal point of view, let's make an example.
Imagne a simplified case. Not this one, nut another one, an imaginary case much simpler than this with just few elements: a woman is found dead, her body is naked and her clothes are ripped off, she has bruises on her body, and she has small bruises on her genital area.
Imagine a coroner that, from a scientific point of view, makes the following observation: there is no scientific proof that there was sexual violence, since bruises on the vagina might have other causes, not always indicate sexual violence. Imagine that someone presents a statystical table indicating medical results, reporting that about 20% of bruises found on vagina in average have nothing to do with sexual violence.
Based on these scientifical findings, it would be possible to draw the conclusion that there is no scientific evidence of sexual violence. If you apply a cartesian method on the scientific discipline alone, this conclusion is correct.
Under a cartesian, scientifical point of view, it would be correct to say that the bruises on her vagina are not proof ox sexual violence.
But under a legal point of view, the bruises found within that evidentiary context are unequivocal proof of sexual violence.
Because the legal point of view does not depend strictly on the scientific quality of the finding. It depends on the capability of the findings to be consistent with each other within a logical evidentiary picture.
When considered under a scientific point of view, alone, bruises on genital area are an ambiguous finding, they can have more than one cause, they are not sufficient evidence of sexual violence.
An argument based on cartesian doubt however, based on the insufficient quality of scientific evidence alone, will be simply
rejected by a judge, because such kind of argument given the contxt would be logically pointless within a legal venue.
To any judge, the bruises on the victim's vagina would mean
only sexual violence, and they would be evidence of it. And that decisioon would be logically correct. Because when the element is found
in that context, within that set of evidence, it only means
that and nothing else, from a judicial point of view.
The value and meaning of each piece depends on its context.
Not only that. There are also other considerations to be made, that I can't say all now. For example involving the modernity or accuracy of instruments (methods, research, experts) employed, or about possible criticisms to this or that witness or merits of testimony or opinion.
Imagine for example that the coroner who is called as a witness for the prosecution to give an opinion about the victim's bruises is found out to be a drunk, incompetent guy who makes scientificaly incorrect statements and gives an inconsistent testimony. Imagine he says: "Yes definitely this is 100% proof of sexual violence"; and then, imagine a defence expert instead brings out a more correct table and says: "Look, it's not true, There is 20% of probabilities that this is not the case".
The fact that the coroner gets discredited as an expert, would that change the nature of the evidence, the judge's decision and the outcome of the trial? The answer is: no.
Even if the evidence is imperfect, and even if the witness was inaccurate and presented an opinion that does not match the truth or the best scientific method, may well change nothing. Would change the point of view of from peer-review in that discipline, but the judge in that trial may have good reasons to just come to the same conclusion, that that piece of evidence has only one possible meaning. Its meaning, under a logical point of view, does not depends strictly on its scientific quality nor on the quality of the witnesses. From a legal point of view, the fact that there is a reasonable doubt on a certain scientific, cartesian aspect of a finding, does not affect its value as a piece of circumstantial evidence.
