IMO the way the RIS Carabinieri reported to the Nencini court is the model that should have happened with Stefanoni at the Massei trial.
The RIS Carabinieri simply brought everything with them as part of their report to the court, which became available to both sides upon acceptance by the court. IIUC this also included all the raw data, so that both sides could make of it what they would.
This is called transparency.
Machiavelli used to argue that it was the courts' responsibility to enforce Stefanoni's lack of disclosure.... and then when a poster would then show how a judge erred in letting Stefanoni get away with things, Mach would devolve into saying, "Well, the defence never objected." When a poster here would show that, in fact, the defence objected all the way along, Machiavelli just went silent.
This is called a lack of transparency on the part of the court.
Yes, I agree that is the way the forensic results should be presented, to the defense as well as to the prosecution. That conforms to the Convention and Italian law. But what I had meant in my question was who among the police actually saw Stefanoni's full work, or was it only seen by PM Mignini and other prosecutors. (If anyone posting here has any knowledge of this.)
