The issue isn't whether someone else had a contrary opinion: the issue is that (just going by the linked reports) Bernardo De Bernardinis came out from the meeting with the scientists and informed the public that there was "no danger". Now, either the scientists felt that this was a reasonable summary of what they had said, or they didn't: either of those is bad, in different ways.

To be fair, it looks like there was fraud in the Italy case - just of the builders not the scientists.
