Voir Dire would have delved into how someone knew about the case, and if they read about it and discussed it with others, etc, etc. Not just be aware of it, but case followers like those on WS who are talking about the trial day in and day out would be booted from juror consideration (and they should be, I don't have a beef with that). Since I've followed the case in detail and have formed opinions about the case and would disclose that during voir dire, I would not be a part of this jury even if I wanted to (which I wouldn't want to, but my desire to or not is neither here nor there).
I still think that's incorrect. There nothing in voir dire to prevent someone who followed the trial even as closely as here on web sleuths from serving. Even if they have an opinion on guilt or innocence. They are asked if they have formed an opinion and if they can be open minded. Though one side or another may not want that person on the jury. Just depends on what they say. I can see some posters here being qualified to serve.
