I think this is interesting to read and constructive for the discussion, but "a scientist who was a witness" is a fairly misleading description. This is not like an independent expert that was just called in for the trial, which is what I first thought when I read your description, this is someone with a very long (10+ year) history of personal conflict with Mann. That doesn't mean anyone should discount his opinion, but it's very important context for reading the post.

> As I said at the trial, Mann has not been the best colleague to me, but I am fine even so. Who knows what demons haunt him and why he behaves the way that he does. I do hope he can find peace at some point.

Clearly this person's perspective is driven by more than just being "a scientist".

Thank you for sharing this. It's interesting to see this perspective.
