Having been a part of a mock jury myself, I think I would seriously consider waiving my right to a jury trial and agree to a bench trial. I don't think regular jurors know enough about the law to render a verdict based solely on legal issues. A jury trial is more about one set of lawyers pitting themselves against another set of lawyers. The defendant's true guilt or innocence may be a minor point compared to the back-and-forth arguments between skilled debaters.
When I was on the mock jury, there were other jurors who just wanted to vote "guilty" and go home. Some of us tried to make valid arguments about the evidence, but others only chose to focus on one or two points, like prior convictions or gun ownership. It was like the rest of the testimony didn't matter. I wouldn't want my own life to depend on the opinions of 12 ordinary people. I'd much rather let a competent and experienced judge weight the evidence and render a verdict.
