As I mentioned earlier, I did serve on a jury in a criminal trial one time. And, after that experience, I firmly believe that everybody ought to experience the role of a jury member at least once in a lifetime. It really is an awesome responsibility. You have the freedom of another person in your hands. You don't want to make a mistake and send an innocent person to jail. And, contrary to the easy opinions we form when watching TV news, court, and/or tabloid shows, the weighing of evidence is a serious matter. I know that my view of the justice system and criminal trial procedures was deeply affected by serving on a jury. In my particular case, we acquitted the defendant because there were just too many missing pieces in the evidence which did not come close to being "without a reasonable doubt." People who criticize jury decisions generally have never sat in a jury box and passed judgment on another human being.
ADDENDUM ADDED OCTOBER 29: As instructed, I called in to the automated system every evening last week. And I got the same message each time; I did not have to report on the following day. This time around I fulfilled my obligation on the telephone, not at the courthouse. But if everything remains as it has in the past, I will be called again in about 18 months.
