I have to say, I am worried about reasonable doubt. It is a difficult concept to deal with as a juror, at least it was for me when I was on a jury, because you are forced to ask yourself if your doubts are reasonable or not.
It is easier, imo, to write off your doubts as reasonable and vote NG than it is to convict someone of murder. I think it is hard, on a personal level, to convict. You have to live with it.
So, sitting here at home, I see no reasonable doubt, (I actually see no doubt), but it really comes down to the courage of those jurors, imo. And I think Mason's chart gave them a reason to justify reasonable doubt and let themselves off the hook, if one or some are thinking about it.
Makes me nervous, but then again, I always get nervous about juries. I had the same, or worse, fear about Scott Peterson and it didn't pan out there.
