To offer a counterpoint, when I did jury service the other jurors were one of the few parts of the justice system I left with more respect for. Everyone took their duty very seriously even those who were self-employed and thus directly losing out as a consequence of the jury system. If it were me in the dock, I would rather face twelve of my countrymen than officialdom alone whose shortcomings were thrown into relief by the conduct of the jury in my view.
