That’s not what Conti and Vecchiotti concluded, though. They agreed that the DNA on the knife matched the victim’s. Their criticism was that the amount was not large enough to allow for repeated testing, so they argued for the evidence to be dropped:

We could go back and forth like this forever. You could keep pointing to one website, and I could keep pointing to another. But, I don’t think we’ll change each other’s opinion.
Is this or is this not the conclusion of the report re: the knife:
ITEM 36 (KNIFE)
Relative to the genetic analysis performed on trace A (handle of the knife), we agree with the conclusion reached by the Technical Consultant regarding the attribution of the genetic profile obtained from these samples to Amanda Marie Knox.
Relative to trace B (blade of the knife) we find that the technical analyses performed are not reliable for the following reasons:
1. There does not exist evidence which scientifically confirms that trace B (blade of knife) is the product of blood.
2. The electrophoretic profiles exhibited reveal that the sample indicated by the letter B (blade of knife) was a Low Copy Number (LCN) sample, and, as such, all of the precautions indicated by the international scientific community should have been applied.
3. Taking into account that none of the recommendations of the international scientific community relative to the treatment of Low Copy Number (LCN) samples were followed, we do not accept the conclusions regarding the certain attribution of the profile found on trace B (blade of knife) to the victim Meredith Susanna Cara Kercher, since the genetic profile, as obtained, appears unreliable insofar as it is not supported by scientifically validated analysis;
4. International protocols of inspection, collection, and sampling were not followed;
5. It cannot be ruled out that the result obtained from sample B (blade of knife) derives from contamination in some phase of the collection and/or handling and/or analyses performed.

Having read that conclusion are you going to continue to insist that the knife was the murder weapon???
