I really respect Ed Weissman's contributions and knowledge, so this is not meant as any type of personal attack. But I was thinking back when I read this comment four months ago that it seemed unusually harsh for someone who was facing 35 years in prison for something that _might_ deserve a slap on the wrist. So it's not all hindsight.
I was also surprised that it was the most-upvoted comment of the thread. And it also wasn't the only harsh comment in that thread. So if anyone deserves criticism, it's the Hacker News community for not showing a more compassionate side. I'd rather say it was the responsibility of the community as a whole rather than a single person.
It makes no sense to discuss if anything would be different if the HN community had responded differently to this story, but in general, giving an unsupportive collective response to someone who is down is probably not the best idea.
