I'm fully behind you with Webb, Tobe and Barni. If they say that when you have a positive luminol test followed by a negative TMB test and no confirmatory test for blood, that it is safe to conclude that there is blood, then I will re-evaluate my position. Perhaps they have something to say about the absence of DNA in blood samples too. Where do they write about these things?
Machiavelli said:
What they say is that it is possible, not that it is "safe"; it does not contradict any scientific knowledge. You can safely predict that if latent stains are highly diluted (which is somehow in the nature of latent stains) blood won't be detected by other tests.
But the point you seem to miss is another one.
It is only up to the judge to determine what evidence means, like to conclude if latent stains are blood or not. There is no requirement that some other discipline determines that.

Thank you for confirming that judges can convict on the basis of something being possible.
Machiavelli said:
The nature of single pieces of circumstantial evidence is to be not probative.
There is no requirement for single pieces of evidence to be proven beyond reasonable doubt.
Even less, there is no need for single pieces of evidence to be proven by scientific method.
It is a disingenuous spin, though, to translate this as saying that judges convict on "something that is only possible"; pieces of evidence are indicative, not just something possible.
Sometimes it is useful to track a sub-thread, so as to see how things follow.
Kauffer wants to know why others refuse to accept that whatever it was that luminol detected, it is proven as "not blood" by a further specific-confirmatory test.
Machiavelli presumably then sneaks a point in under the radar that the confirmatory itself is not 100% accurate - therefore it could be mistaken. All true (Why this reasoning then is not applied to the luminol, that it, too, could be mistaken, is beyond me. Then again, Machiavelli's purpose here is to Bewitch, Beguile, And Bewilder like Pal Joey...)
The convicting judges, one of them himself who used the term "presumed blood" multiple times to assess the blood evidence, seems to agree with Machiavelli. It seems that just because the confirmatory test has "ruled out" what was tested as blood, the good judge nevertheless accepts the proposition that:
What they say is that it is possible, not that it is "safe"; it does not contradict any scientific knowledge.
It therefore is safe to conclude that judges in Italy, acc. to both Nencini and Machiavelli, can convict on possibilities, even when the large weight of probability is against them.
Machiavelli then shifts the goalposts:
- "The nature of single pieces of circumstantial evidence is to be not probative." So even if some piece of evidence does not tend to add to "proving" the case, it still can be used.
- "There is no requirement for single pieces of evidence to be proven beyond reasonable doubt." Machiavelli just chucks this in there, not realizing that his first point covers this. If an item of circumstantial evidence does not even have to be probative, it most certainly does not need to BARD.
- "Even less, there is no need for single pieces of evidence to be proven by scientific method." At least there is one claim by Machiavelli that one can sink their teeth into. You see no one has said this. What is at issue if you read this thread through is if a single piece of evidence has been disproven by scientific method.
Reading Machiavelli and following the thread as he dances and weaves and Bewitches, Beguiles, And Bewilders like Pal Joey, is instructive.
He's the one who tried to conclude this thread with the baffling.....

We've moved from safe evidence, possible evidence, non-probative evidence (which in other words is non-evidence!!!) to BARD evidence, to evidence disproven by the scientific method, to .......
Bewitch, Beguile. Bother, and Bewilder:
Wise at last
My eyes at last
Are cutting you down to your size at last
Bewitched, bothered and bewildered no more
Burned a lot
But learned a lot
And now you are broke, though you earned a lot
Bewitched, bothered and bewildered no more
Couldn't eat
Was dyspeptic
Life was so hard to bear;
Now my heart's antiseptic
Since you moved out of there
Romance-Finis
Your chance-finis
Those ants that invaded my pants-finis
Bewitched, bothered and bewildered no more.
