Well, unless you 'know', you can't state it can you?
I didn't state it. Speaking hypothetically, I wrote:
"One mistake on Rudy may represent 5% of his data, whereas one mistake on Raffaele represents 100% of his data."
To which you responded,
"Only the lab didn't make any mistakes with Rudy, did it?"
I then asked you how we would know whether they made mistakes, and you set up yet another Straw Man, as is your habit.
Deliberately falsified? I see absolutely no logic (not to mention no evidence) to support this claim. Why, oh why...if they were going to falsify the evidence, would the put Meredith's DNA on the blade of a volume SO low on the blade the machine could hardly read it and there was not enough to retest? WHY would they not have put a high volume of Amanda's DNA also on the clasp? WHY not place Raffaele's DNA in some of luminol prints? If that's your idea of a falsifying evidence...
"Finding" Meredith's DNA on the blade of the knife was the first piece of falsified evidence. I actually think Patrizia Stefanoni may have had mixed feelings about it, but eventually realized she had no choice, so forced the results. I sincerely doubt Stefanoni or Mignini thought anyone would question the results, so they didn't feel they had to be terribly brilliant about the whole thing. Anyway, "running out" of sample -- another obvious contrivance -- assured that nobody would be able to double-check the results.
By the time they falsified the bra clasp, they had a lot more at stake -- the kids had now been in prison for six weeks. It was time to be blatantly corrupt. They managed to find "copious" amounts of Raffaele's DNA, which might not be suspicious if we didn't know they had access to copious amounts of DNA by virtue of the fact that Raffaele was in prison.
I suppose they could have availed themselves of copious amounts of Amanda's DNA, too, and placed it somewhere, but since they hadn't thought of it soon enough, maybe they didn't want to push their luck. Even the prosecution seems to have had some limits to what they thought was acceptable vs. what was ridiculous.
RE: the luminol prints -- any investigations at the cottage were more public than the investigations in the lab.
