Get the "confirmation bias" cut and pastes ready, and add this to the ridicule sent to Lowe.
Nevertheless, IMHO,
1) Sollecito suddenly felt a very strange necessity and timing to extemporaneously come forth with his ludicrous cock and bollocks fabrication about pricking Meredith's finger with that knife in question.
2) That "stupid kid" story revealed more to me about what he thereby confirmed was *at one time* in sufficient quantity on that blade than any subsequent tests needed to.
3)Add to this the defendant documented anxiety about "what might be found on the knife" and then believe and send to leader Lowe what you may.

haha
Context is king, pilot. Open your eyes and read what he

Raffaele's Diary said:
Nov 16 2007
Last night I saw on television that the knife that I had at home (the
one from the kitchen) has traces of Meredith and Amanda (latent) ...
my heart jumped in my throat and I was in total panic because I
thought that Amanda had killed Meredith or had helped someone in the
enterprise. But today I saw Tiziano who calmed me down: he told me
that the knife could not have been the murder weapon,according to the
legal doctor, and has nothing to do with anything as Amanda could take
it and and carry it from my house to her house because the girls
didn't have knife so, they are making a smokescreen for nothing ... I
live in a reality show nightmare, the 'nightmare reality show'.
Unbelievable!
I am starting to have perpetual panic attacks and palpitations due to
...in the anticipation of these scientific tests that fire shots
unsettling of this sort... Oh God, it is not their fault but of the...
who take everything that they can involve in this story.
I want to think about other things, think of my friends who are close
to me and think of fathers in these moments that will stay very badly
and will be worried and I am very sorry. I do not know what to do.
Please Jesus give me the strength and reason to deal with this
situation and I pray to support also dad who is sustaining an absurd
situation.

they are keeping me in jail because there is a kitchen knife with a
trace of Meredith's DNA. It seems like a horror movie ... Looking back
and remembering it came to mind that the night dad sent me an sms
message of goodnight to be indiscreet (knowing that I was with
Amanda), then the day after Amanda repeated to me that if she had not
been with me at this time she would be dead. Thinking and
reconstructing, it seems to me that she always remained with me, the
only thing I do not remember exactly is when she left in the early
evening for a few minutes.
I am convinced that she could not have killed Meredith and then return
home. The fact that there is Meredith's DNA on the kitchen is because
once while cooking together, I shifted myself in the house handling
the knife, I had the point on her hand, and immediately after I
apologized but she had nothing done to her. So the only real
explanation of the kitchen knife is this.
I am not quiet because if they have found a trace so ridiculous they
can find many so many others on the rags and so on ... What a
nightmare! They should first of all show that the knife is indeed the
weapon of the crime: knife, type of cut, the obvious traces on the
blade, etc.. Then if they want to find invisible traces of Meredith in
my house, find some in the streams of this passage! There must be a
divine justice to all this! I continue to wake up in the morning with
accusatory faces that fix me as a murderer ...
Read that passage in totality, Pilot, put together the information it offers. Raffaele
knew the knife wasn't the murder weapon, he'd been told so by someone relaying the coroner's report, however he was being kept there because they said DNA had gotten on the blade somehow. Being as he's innocent, he can't quite figure out how the DNA could have gotten on the blade, but the other thing he is told is Amanda could have borrowed it and taken it to the cottage. How in the hell is he supposed to know for sure, the knife is a common one found in any kitchen in Italy, it wasn't even his as we've been told repeatedly by bunnies, kittens and gargoyles assuring us his landlord would be pissed if it's missing, so if murdered anyone he'd have to put it back!
From the first page entry on the page I linked:
Raffaele's letter to Telenorbo said:
"Put yourself in my clothes", writes Sollecito, "I meet a girl in a concert and from that moment we start going out. She lives with her friends and often I have lunch with them, I'm often at their house."
So what does Raffaele know? He knows it's not the murder weapon, but the cops are using it to hold him and Amanda in jail. He knows one explanation for the DNA being on it is that Amanda borrowed it to take to the cottage. He knows he often had lunch with the girls at the cottage and remembers an incident that took place when he was cooking--that has to be it! See! Raffaele can put on a bunny suit too! The
'only' explanation has to be that Amanda had borrowed the knife and it was the one he was using when he shifted and accidentally almost pricked Meredith. From the 'find invisible traces of Meredith in my house, find some in the streams of this passage!' part he might even have been kidding about it! You
don't know for sure what he meant, but what you
do know is that when he wrote it he'd been told it wasn't the murder weapon, but they were just using it to keep him in prison and he was kinda pissed about that as you can imagine.
Here's the thing though, Pilot. If they didn't find blood on that blade, then any DNA they found
wasn't the result of the murder. Like the
Doctor of Biochemistry has been trying to tell people for two years now, that's basically impossible, it requires 'magic cleaning fluid.' You ought to be able to tell from other arguments made, notably with the luminol footprints, that it is possible to detect blood without being able to find DNA, it doesn't really work the other way around! They found starch though, didn't they? Thus no 'magic cleaning fluid,' and the starch basically proves there was never blood on that blade, and if there was never any blood on that blade it sure as hell didn't make a neck wound which sprayed blood out to the wall.
So, how is it that you can take a distorted reading of that passage and pretend it overrules scientific evidence? Or any of the other more plausible explanations of why he might ponder in his diary as to how the seemingly impossible could have happened? What would you think if you were in Raffaele's shoes, sitting in prison because they said their found the DNA of a murder victim on one of your knives, and you had nothing better to do all day than try to think of ways it might have happened, knowing full well you weren't a murderer, and coming to the conclusion that the cute girl you'd been cuddling with couldn't have done it either?
If logic won't convince you, just look at the guy, does he
really look like a murderer to you? Or does he look like a guy who'd rather spend a cold November evening watching movies and cuddling with his first real girlfriend?
