That's why jury members shouldn't be the average, possibly dim, possibly outright stupid, possibly just apathetic person, but actually be required to posses at least a modicum of intelligence, so as to be able to research minimum sentences etc.
Yes, but if we make it easy for anyone who can fog a mirror to get out of serving in combination with throwing anyone off who the prosecution thinks might be able fog a mirror, then we can expect that who ever is left will have few problems.
My feeling is serving on a jury it is a bit like voting. I know it is unlikely that I am doing any good, but it is my duty to do my best in both circumstances.
