1. They are already punished appropriately, as determined by law. We don't need social internet warrior vigilantes to damage their lives further, and more importantly their innocent families or friends. This is an incredibly dangerous crowd mentality aggression that can really hurt more than just the people directly involved.
2. Until their verdict is determined, they shouldn't be persecuted. Cases like these happen all the time in which the "predator" is found innocent but the damage is done. Thousands of angry hate mails, maybe your job already lost, sometimes even physical violence. We see it all the time. Which brings us to something very interesting...
We're probably having this discussion about that event in comic con right? Everyone should read the updated news story on it. Turns out there is a high probability that there wasn't any sexual assault at all, and the girl in question just fell and was knocked unconscious. This is exactly why its such a huge relief that the suspect in question hasn't been "revealed" to be publicly shamed before we knew the full story. We're not entirely certain on the truth yet, but we should always try to be civil and level headed about these things rather than getting angry and raising our pitchforks. Its honestly embarrassing.
I don't know if I'd go as far as to Name-And-Shame, but definitely ban them from future cons as well as ejecting them from the current con. I personally don't think that the NaS method works on these types of people, after all they are doing it in a very public area, even if it is as subtle as grabbing an ass-cheek while getting a photo taken, they probably aren't that worried about getting caught, for whatever reason some part of them sees nothing wrong with what they are doing. Shaming them for it probably wont change that.
what pisses me off the most is the amount of "what do you expect when you go around dressed like that in public" comments I've been seeing around the web, like come on.. I just feel genuinely sad that her first comicon was ruined like that, I imagine the excitement the joy that she was actually there just shattered, she'll probably develop a fear of strangers or dressing a certain way and ugh... when I think about what might be going on in the poor girls head just makes me so sad.. <:/
No. For years, I have been against the stigmatization of criminals and especially the sex offender registry. I figure the best way to deal with this problem is to have a *private* list for administrators to ban people from cons. Public shaming is only going to make the problem worse.
It's going to focus attention on pointing out and shaming the perpetrator as opposed to having fun at the convention. The crime has been committed, the perp served time, the admins know ahead of time, it's in the past. Public stigmatization only encourages harassment, which in turn creates more problems.
