I was on Federal jury duty and regular. Only two times in my life so far. It is nothing like you see in the court room tv shows or movies. Really I was ready to convict most of the fellow jurors on the jury I was on for being so soft hearted toward a mean, nasty, soon knock you in the head to look at you drug addict. Jury chairman is not a scary job, just someone to keep the votes counted and fill out the form to give to the judge. One we had to award a settlement. All 12 of us wrote down what we thought was a fair amount. It was added up and then divided by 12. The answer was the amount we awarded. As far as not having any pre set opinions, you hear the case and it was plain on the trial I had, it didn't matter what I thought, the person did a terrible thing and had to be voted guilty. We had to set the sentence too, that was when the arguing was worse, bleeding hearts wanted the min. the others wanted max. plus.
