Tesla why do obfuscate?
Did anyone credible say the DNA was starch? Yes or No.
I do not trust her work or conclusions. I don't think that the knife or bra DNA should be admitted to any court, but it wasn't found to be starch.
If you can't admit it, just let it go.
You obviously think you're making a very clear point (I think it's more a matter of scoring a point), but really .....
"The DNA"? Meredith's DNA was in Stephony's lab in copious amounts, there's no question of that.
She produced a chart showing RFU peaks which are barely above the 'noise-floor' the machine produced, i.e. at the very limits of its ability to differentiate them from nothing - by definition in the LCN range.
Her own notes show that the blade tested negative for human tissue or blood, yet she claims she found a "speck" (which she didn't photograph), and which she claims was the source of this infitesmally small amount of DNA.
C&V confirmed no human tissue or blood, only visible traces of vegetable starch.
Assuming Stephony DID actually find a "speck", then in all likelihood it TOO was starch, and the DNA was from elsewhere in the lab
Once again - since this matter [ETA >> i.e. the starch] was on the blade, at the junction with the handle, exactly where one would look for something missed by cleaning, what rationale could there possibly be for Stephony ignoring it, while just happening to get lucky with the single other "speck" on the blade that yielded DNA? Do you honestly find that remotely credible?
Whatever, had she produced charts for negative control runs which showed only noise (the controls aren't an "option" to "just make sure" of the results, they are an integral part of those results), then it would be credible that her "speck" did indeed yield the few picograms of DNA.
The only thing then standing in the way of presenting it as "evidence" would be complete, unambiguous records/documentation of the "chain of custody" of the knife, proving that the absolutely mandatory procedures for sterile collection, handling and storage had been observed ........ er, oh dear.
Methinks you really need make some effort to get a more thorough grasp of this "DNA science stuff", if only a 'lay' one.
BTW, I have to assume you don't bother reading at IIP (it's too "biased", I suppose), because if you had, you'd be aware of the time and effort Diocletus has put into doing exactly that, and I doubt you'd be so ready with the condescending tone when discussing this particular issue with him.
