Open Inquiry,
FOA have the complete transcripts, case file etc. the whole works. I'm on the point of bowing out, but my suggestion would be to persue them to share it, publish it even. They can tell you, if they choose, exactly what Stefanoni said during her testimony, what questions the defence asked and what she said in reply. They have copies of all of their requests to the lab and the court for forensic information, lists of what was and was not contained in the hundreds of pages of material that was handed over, and copies of their complaints to the court when that information was not forthcoming.
They can provide you with certainties. Here we are forced to make judgements based on who we think is reliable, and who we think is telling the truth.
If you have a few tens of thousands of euro you could get all this information from the court yourself.
