I can't reply to the child comment, for some reason, but to expand on this idea: a jury's role is to basically decide if the facts as presented apply according to the law. The frustration technical people express is mostly that they want to decide what the law should be as part of the jury. This defeats the point of the legislative branch: if you want laws that make sense in a technical way, devote your life yo becoming a senator or congress person. Don't expect juries to suddenly gain the power to overturn laws because they "know better".
