contrarily to what I'm reading here, I think that it is a good idea that the trial goes on. The point is not that a best estimate was wrong, but rather that the conclusions could have been steered by political pressures, which is actually not unlikely, considered the history of man-made or man-facilitated disasters in Italy (e.g. the Vajont dam).

I believe that the purely scientific advisors will be cleared at the end, but bringing everyone to trial is inevitable as the firt step. ("inevitable" in standard italian judiciary practice, that is).
