I can't exclude those involved in this willfully not reporting errors they recognised: indeed my statement implicitly includes that as a possibility.
So why do you keep saying that it was Rossi who misused instruments in order to deliberately spoof the profs? It didn't happen for the 1st academic report (Bologna) and there is no reason to think that it happened for the 2nd (Ferrara) or 3rd (Lugano) reports.
