I originally tried to submit this about an hour ago, but either the website didn't respond or my DSL was out a while:
Is there not some contradiction inherent in these two objections?
It seems that on one hand the objection is that the investigators couldn't have found everything, and then later the objection is that they didn't. This is a good technique for obfuscation, but it doesn't lend itself well to rational review of the data.
I'm sorry if I expressed myself poorly.
The witness for the prosecution mentioned in Fiona's quote said that the only other source of Solecito's DNA in the flat besides the bra clap was the cigarette butt. This was offered by the witness to support the contention that it was unlikely that the bra clasp could have been contaminated with Solecito's DNA from having been left in the apartment for 46 days.
I added the word
identified to the quote because, as JihadJane source pointed out, there could have been more of Solecito's DNA in the apartment besides what was on the cigarette butt. I thought that biological matter could have been tracked onto the clasp after the murder, but JihadJane's source stated that DNA on the bra clasp could have been left before the murder from Solecito's presence such as his use of the bathroom.
Are we quite certain that alien space lizards didn't transmute all the evidence from gold into base metals? Any number of things are possible and defenders of the accused will attempt to plead them as possible. For there to be any merit to the pleadings there should be at least a test of likely. Is there some data beyond "Well. It could have happened." that we have not had shared with us?
Leaving aside discussion of the merits of that accusation how is it of significance unless some demonstration of evidence tampering is forthcoming? Does that accusation include demonstration of prior evidence tampering?
Can you think of any case where an allegation of the possibility of evidence tampering could not be brought up? How would you weigh the value of such assertions as a general defense?
I was speculating on alternate possibilities to the the prosecution's claim that the DNA on the knife and bra clasp was placed on them during the murder. You feel those possibilities are as remote as alien space lizards. I think they're far more likely. Even in the past couple of years in the US there have been scandals in US forensics labs and cases of DNA sample switching and evidence lost from storage.
In a trial, it comes down to how much the jury trusted the involved police force, chain of custody of evidence, and forensics lab.
Given the prosecutor's zealotry in this and previous cases, the poor handling of the crime scene, and the Perugia police's abusive interrogation, I think reasonable doubt is raised by the possibility of DNA contamination when weighed against the absurdity of the prosecutions claimed motive and the improbabilty that Knox and Solecito would have carried the murder weapon back to Solecito's apartment and put it in his kitchen. Were they really so in need of keeping kitchen knives that they wouldn't have just disposed of it?
It is not clear what you are trying to say here. You point out that the O.J. jury disregarded a wealth of valid evidence because of the possibility that some of it might have been tampered with and found him not guilty.
I don't understand how that applies to Knox's conviction. Are you saying that the Italian jury demonstrated error because they did not arrive at the same flawed conclusion as the O.J. jury for the same flawed reasons?
Comparing the Knox case to the OJ case was probably a mistake because there are so many cases of some juries disregarding overwhelming evidence of guilt and other juries convicting when the evidence is so weak that there clearly was reasonable doubt.
What I do feel is that the DNA evidence is so sparse in the Knox case and that the evidence of a conviction-obsessed prosecutor and police so strong in the case that a jury would be justified in feeling that the existing DNA evidence could have resulted from willful or careless contamination.
However, the forensics expert shown by JihadJane said that the DNA evidence is so weak that contamination by the police may not have even been necessary to explain it as not being due to the crime.
For either reason, I would consider there to be reasonable doubt that the DNA evidence indicates Knox's and Solecito's guilt.
