Which we don't need, because a bunch of HN commentators handily volunteered to conduct a trial on the spot, right? Forming mobs is really what humans do best.
I wonder if that's what Aaron felt when he asked for help: that HN had formed a mob against him. That's certainly the impression I get from reading the original HN thread (that HN turned into a mob against Aaron), yet there's not a single comment directing HN's attention to the fact that they were behaving like a mob.
