In my county, everyone in my family gets called about every two years. They are large panels and we only get chosen for the jury about one out of four times.
It really bugged me at the time. I might not have felt that way had I seen others being called at the same rate.
I am still a believer in the system, as flawed as it has become. If they called me now, I would go without protest. Back then, I was a young and busy man, and felt I had much to do.
