That wasn't what I gathered from the discussion there. What I gathered is some posters are saying that the report does not appear to disprove that Raffaelle's DNA is on there. The report states that Stefanoni should not have "cherry-picked" (my phrase) the data. i.e. she should not have selected the peaks which matched Sollecito's and ignored the peaks which did not match him.
The discussion goes on where some of the forum members said they see no problem with matching the peaks to the suspect, since the point of looking at the information is to see if it proves a suspicion.
The response to this is that this evidence is absolutely NOT to be used to prove a suspicion. The evidence is supposed to be an objective fact. A disinterested third party should be able to come up with the same profile.
The implication from the CONCLUSION of this new report is that a disinterested third party would NOT have come up with the same profile Stefanoni came up with.
I agree with Otto, however, that this discussion is complex because none of us DO know what the "standards" are for DNA testing and results. Using disposable tongs SEEMS like a very simple, standard practice, but perhaps it is not universally accepted.
That being said, doctors didn't used to wash their hands, and they killed a lot of people. Some common practices are dangerous. If disposable tongs are not widely used, then I don't think it takes an expert to surmise that one could transfer DNA from one place to the next.
IS Raffaelle's DNA conclusively on the bra clasp? What does the report say?[/QUOTE]

It states that a Y haloptype is present along with some others. There is a percentage of the population that would have this probably in the thousands. RS happens to have the Y (being male) haloptype. They are also pointing out that the one main one being MK's and the lower count ones cannot be excluded from contamination. In other words there are more than one profile on the clasp that would match alot of different people but cannot be said to be one person in particular. The reason it seems they cannot exclude contamination is that there are so many profiles showing and due to the collection methods and fact that it was not collected for 46 days, passed around, and was found in a different area than where it was original photographed. As well they picked it up, appeared to forget to photograph it and put it back down on the floor
