The "independent scientific opinion" asserted that the additional sample on the knife handle at the blade was too small to be tested. In the next trial, it was tested successfully. Why should anybody think those "experts" were objective and/or competent?
Welcome to the forum.
The original Scientific Police destroyed Sample 36B, the claimed sample belonging to Meredith on the blade. They did not do thissuspiciously, there was only enough sample to allow one test.
In fact, its very claimed presence was a bit of a headscratcher to begin with. The claim was that the destructive "test for blood" would destroy the sample ( a correct claim), but this then begged a huge question. How could this sample survive the claimed bleach-cleaning of the knife, if the test-for-blood would eradicate it?
Enter the further baseless claim. The groove on the knife in which Stefanoni claimed, and Massei accepted, the sample had been protected. This is a striation no one else say, including the expert at the preliminary hearing, who was on the original prosecution's side.
The PMF website claims to have a picture of the knife which shows the groove. Yet the Massei report specifically mention why the groove cannot be seen, an specifically outlines the special lighting conditions Stefanoni said she had to use to see something no one else saw.
I think at this point any reasonable judge would have simply thrown out the sample 36B as useless. But no, it becomes the hinge on which others find guilt. Others even add a bit of hyperbole when they claim that there is "abundant evidence" to suggest their guilt.
But let's go back. This evidence no longer exists. Unlike sample 36i which was testable and verifiable (as Amanda's) four or five years later, sample 36b is non-verifiable and the electronic data files have not even been released to demonstrate why the "one-off" test should be considered valid.
The raw data for DNA was disclosed. It was referenced in court according to the transcript.
A crime lab isn't conducting science. It isn't research.
WTF!? It's not science? Well, quite literally what Stefanoni did, and what Massei signed off on, was actually NOT science, which is a reason for their conclusions to be discounted. This is a stunning admission.
