Did you also happen to catch this rather telling quote in the same piece from Gen Garofano (an erstwhile pro-guilt favourite no less!) about the farcical nature of crime scene forensic investigation in Italy (my bolding):
And former General Luciano Garofano, long head of Ris of Parma, admits the cultural lag, "The police has made leaps and bounds in the technique of the inspection and the laboratory tests, but much remains to be done. At the crime scene should go only pure specialists that we have not."
It's a shocking and manifestly dreadful error that not-a-real-doctor Stefanoni and her crew were let loose on the crime scene in the cottage. They obviously did not know how to do things properly, yet they blustered and blundered on regardless. In the process of course, they compromised, contaminated, destroyed and overlooked (in varying degrees) pretty much ALL the important physical forensic evidence in this critical case. At least they had the decency (hubris?) to videotape their slapdash and harmful efforts, which would be comical if they didn't have such serious implications.
