Jen and the justice system

I've gotten summoned for jury duty. Not only do I not need to know much about the law, but I don't even need to know much English. Call me what you will, but if I am ever involved in a criminal court case, I want the 12 people deciding my fate to understand all the facts, and all the whos and whys and wherefores. I'd want my jury to speak English well. I'd want them, the people who will decide if I'll live in a jail cell, or pay a hefty fine, to understand all that is said.
I had jury duty last year. I had to get up early to drive to a train station so I could take a train into the city, where I'd have to get off and walk a mile before I got to the courthouse, where I got to sit around and wait for an hour. In those quiet times, you wonder, "Why, when I haven't done anything wrong, am I being forced to sit here and waste my day?"
My mind goes back to the day some thug stole my dad's bike. After the bike was recovered by the police, the thug who stole it was still loose, (probably stealing other people's bikes), and because of some law that I'm unfamiliar with, the police were holding my dad's bike. So my dad, who had done nothing wrong, was being punished by being unable to ride his bike because the bike was in jail while the thug who stole it was out running around.
