I don't think its as simple as that - the contamination argument has already since been rejected by the supreme court as it doesn't hold water... the delay isn't massively relevant,DNA has been collected in cases after much longer delays, it doesn't just magically appear. The Bra Clasp wasn't 'almost black with dirt' either.
Dna actually can just appear, particularly when the same video's showing the clip show forensic investigators touching things without gloves, improperly handling evidence.
The point is over 46 days how many people walked around that apartment, and how many times, how many people may have trodden on or kicked that bra clasp around, then it was found under a pile of clothes or rags. The apparently tiny sample of dna could indeed have been tracked into that room by incompetent idiots, over 46 days of being trampling there is no way to say where the DNA came from, or even if it was found on the clasp and not contaminated at the lab which is also possible.
Again it's not really saying it definitely isn't his DNA and it definitely wasn't there, it's a case of after such horrendous mishandling being very much able to say it wasn't definitely there originally.
The more you read up on it the more ridiculous it gets frankly.
One of the reasons they were found not guilty is because the judge ordering re-examination of the evidence, particularly on the knife and the bra clasp basically show an idiot forensic investigator using equipment not recommended, for unqualified tests, and bypassed parameter's on the machine to get the results they wanted.
The experts appointed by the judge basically said the lead forensic investigator on the case who later admitted that basically there was no evidence on the knife. The knife which was taken from his home to be tested based on..... looking clean, they didn't test or check the other knives. There was no control done in a lab that had been testing huge amount of the victims dna. The police presented it as the murder weapon and explained the lack of blood as... the pair cleaned it, with bleach..... leaving both of their dna on it and the victims non blood dna evidence.......... Yup, they poured bleach all over the blood but again carefully avoided the victim and knox's dna.
If, and I mean if Knox was a world famous forensic investigator with the whole kit, and pre-meditated it, then maybe she could have cleaned up with such precision in the bedroom, but that doesn't explain missing one spec of dna(later seemingly proven not to be hers) on the knife.
Anyway when the evidence was re-examined, the low dna count method they used to test destroyed the minute amount of DNA if it was the victims or not. The method used to test is poor, and it wasn't to detect blood evidence, it could only be certain types from that kind of sample. The knife was re-examined and no trace of blood was found on it at all. There is no evidence that makes it the murder weapon, it doesn't match most of the wounds, there was no blood on it, it wouldn't have DNA on it if it were cleaned, if not it would have blood on it. The judge appointed pair conclude it wasn't the murder weapon and that it's extremely likely the sample was cross contamination.
The DNA clasp, more detail, firstly the video shows forensic investigators touching it and other things without changing gloves, second, the DNA IS NOT a direct match for Sollecito, some strands matched, not all it was merely in a class of dna types that COULD be his, the prosecution failed to explain that to the jury in the first trial. The sample contained the dna of several other people also. It was metal, stored in water(????) and rusted so couldn't be re-examined. The video showed dozens of problems with the collection of the evidence, not changing gloves when poking around the room then touching the clasp, the 46 day delay in collecting it, that it was moved around the room and was found under a pile of stuff.
Neither pieces of DNA are remotely reliable, the overwhelming likely hood is if his dna was on it or the victims on the blade, it was contaminated. Neither samples were proof it was those peoples DNA in question, both pieces of evidence were improperly collected, handled, tested and stored........
But again it's the lack of evidence that is even more compelling. They stabbed her and took the knife home, cleaned all the blood but neither of their dna off the knife? They picked the knife at random, they left no trace of her blood on their clothes, their rooms, no footprints, no finger prints, not a single skin cell.
There has been less coverage of the latest trial because 99% of people know what it is, BS, the uk/us isn't that interested in it. I'm going to presume they managed to re-enter the basically insane, bogus, guesswork dna evidence.
