Well, actually I don't think Massei's narrative (properly, the court of assise's narrative) is the main object of the case and I don't think the evidence depends on the particular logical consistence of the narrative chosen by the court.
If the Massei narrative was false then they were convicted on the base of a false case, correct? If so I cannot see how it can not be "the main object of the case".
You can't legitimately convict someone if it's not possible for them to have done it.
I think I have some more to say about other topics before.
I can say something in advance on the mentioned issues: I simply think the evidence is non sensitive to the time of death. There are several windows were it is possible to locate time of death, it is quite indifferent respect to the evidence, whether Meredith died at 22:00 or at 23:30, with the sole exception of Antonio Curatolo's testimony. But I never consider Curatolo's testimony when I think at the evidence.
As we have shown by citing the peer-reviewed scientific literature, there is no way known to science that a normal, healthy young woman who had eaten a small-to-moderate size meal with no alcohol, serious stress or other confounding factors could have no digested matter at all in her duodenum at 23:30.
No confounding factors with any plausibility have been suggested.
That evidence rules out all times of death later than 22:00, and makes any time of death after 21:30 incredibly unlikely. The most likely time of death by far is the earliest which can be reconciled with the witness evidence that says Meredith wasn't home until 21:05 or so.
This is also consistent with the body temperature evidence, the anomalous phone use and the anomalous 22:13 ping.
Whereas the Massei narrative has absolutely no positive forensic evidence whatsoever to push forward the time of death.
You can either contest these facts with facts and citations of your own, or accept that Meredith almost certainly died in the 21:05-21:30 range and that Amanda and Raffaele are therefore innocent. There is no rational alternative.
The second argument is completely flawed. I think by "desctruction of evidence" you can only mean the modification of log file due to new "last access" data. Even here, there is no reason to assume the police ever accessed the file (there is not even a reason why they should destroy evidence, loosing information doesn't help them). The laptop was on for days after the murder and the file shared on a P2P application all the time.
The alterations to the Stardust metadata occurred six days after the murder while the laptop was in police custody but had not yet (as far as we have been told) been backed up.
There is an
excellent reason for corrupt police to destroy this evidence: It almost certainly falsified the prosecutor's theory that Amanda and Raffaele were in a drug-fuelled orgy at Amanda's place, when they claimed that they were at home watching Stardust.
If the police had the laptop plugged into an internet connection with access to the outside world, which is what it would take for the P2P excuse to hold water, that would be just as amazingly incompetent as destroying multiple hard drives without backing them up, and destroying the evidence which could prove or disprove two of the suspects' alibis.
Past a certain point, the charitable hypothesis that these were the most incompetent computer forensics workers in all of human history ceases to be credible.
Anybody or any automatically launched application can change this log data.
No. You have to open the specific file. The laptop was in police custody at the time, so the only "anybody" with access to do so was the police.
Moreover, there is not much for asserting that a last access on Stardust could be "evidence". The truth is we don't even have the word of Raffaele claiming of the use of Stardus, because Raffaele refused to answer in court and refused to make statements on the topic, so any alleged previous claim of him is unconfirmed hersay and because of his silence his police statements are not entered in the court debate.
This is really a reach. If the file was opened at a time when prosecution witnesses or theories have them out on the town or murdering Meredith that is hard fact, recorded in ones and zeroes, that the given witness was lying or that the given theory is false.
On the other side, there is an evidence that Amanda and Raffaele lied in their recollection of the night (this is a topic itself).
We hear this sort of vague accusation a lot, but please don't get into this sort of petty stuff before you answer the tough questions about the time of death and the computer forensics.
Once we've sorted that out you can cite specific sources to back up the claim that they lied, and we can look at them, if it's still relevant in any way.
