and as to the question at hand, I think the system we have now does a pretty good job. the cops have their job to do, as does the DA, the defendant can get a lawyer to represent, they all go through the process of picking jurors, the judge is supposed to just follow the law although I feel at times that isn't exactly the case, but the end result is usually relatively fair and just.

professional paid jurors would just be another tax hike when the people could judge their fellow citizens instead.

the system isn't perfect by any means but I feel it does a pretty good job.
