Yes, those Massei segments are extraordinary. They 'filtered' the allele scores, as C and V discovered, to present a forced interpretation. That's known as 'doctoring the results', isn't it?
Kauffer - I think all Massei was trying to determine - which he determined wrongly - was if Stefanoni followed a "suspect-centric" analysis, as the defence expert claimed she had.
Massei at least has the cojones to deal with the issue. But when you read the sections where he tries to deal with it, his own "analysis" of it gets lost. Massei is the source of what the ISC in 2013 eventually said about all this - that regardless of protocols....
..... the technician still needs to rely on their experience and intuition. However, in this case, that "experience and intuition" found no need for things like a second confirmatory test, despite protocol. Massei's point of view is, if Stefanoni (the expert) says this is all right, then it is all right. If someone else says it is not all right; even appointing an independent third party to see who's right will only side with one or the other, and Massei says this leaves him no better off than when he started.
This, by itself, confirms Stefanoni's suspect-centric method, at least how Massei deals with it. She's basically saying that there's no need to run a confirmatory test, because: "What? You want me to find Raffaele on the bra-clasp
again?"
Well, yes, that's what confirmatory tests are all about!!! And Massei eventually lets Stefanoni off the hook, with his own brand of, "the technician is not the one on trial here."
Whether or not this is "doctoring the results", is not something Massei deals with, really: except to say he can't imagine why someone connected with the police would do that.
