I got called to jury duty once and will never go again. I'll find some way out of it in the future (I watched as most people simply claimed they were sole propreitors of a business and would suffer irreparable harm, etc. and were let go).
I sat for 2 days in the jury room, mostly working on my computer. Finally, I was juror 9 for an assault trial. As best as I could tell from the questions the prosecutor and defense attorneys asked, a drug deal went bad, two guys got in a fight, at least one of them had a knife and stabbed the other. The prosecution was making it out to be a simple, "he stabbed the other guy" case. The defense was making it out to be a simple, "they fought and my client had the misfortune to win the fight". I was looking forward to seeing what the actual evidence and law had to say on the subject as this didn't seem completely slam dunk from a common sense perspective.
During voir dire, both the prosecution and the defense dismissed every person in the jury and the backup pool (another 32 people) who had more than a high school diploma. A group of about 6 of us grabbed coffee afterwards and marvelled at it. They (both defense and prosecution!) dismissed people as soon as they found out they were teachers, doctors, engineers, etc. And the judge never questioned any of their dismissals.
I decided then and there I was never going to serve on another jury. What a waste of time.
