The system as it stands is not perfect, as most if not all of us have prejudices and preconceptions, as well as situational biases. That's what voir dire is about, both sides have equal opportunity to try to seat a jury that's favorable to their case. Most attorneys actually prefer jurors with a minimal knowledge of the law, as they can be more easily influenced. Professional juries would remove one of the powerful controls from the justice system because, if they are employed by the court system, they would have a vested interest in making sure that the conviction rate stayed high to ensure revenue to the court. Sure, jury duty is not the most convenient thing in the world, but I will serve if called(again), as I feel it is a better system than many if not most other trial processes, and I would like that system to be available to me if the need ever arose.
The judge is there to hear the case, if you don't want a jury. You would get a decision based on law and not mitigating factors.
I have been through several trials dealing with contract issues, damage calculations, business valuations. The juries I dealt with were generally good and look at things in a common sense way. i.e yes the contract says this and is in favor of party b, but party b was out to screw party a. That is just wrong. Verdict in favor of party a.
I have also seen the judge overrule the juries. That is a bitter pill after spending $50,000 on a trial and getting a favorable verdict.
There are a lot of reasons not the trust the court systems. Fairness and logic are lost sometimes.
Can I vote for reinstating public executions? I'll bring potato salad.....
Make it hotdogs, burritos, and gyros and I'll come. I won't even open my mouth for potato salad.
