There are only a few things that are required of U.S. citizens other than obeying the law. You must pay your taxes. If you have children, you must send them to school. If you drive a car, you must get it licensed and insured — something you don’t have to do with much more dangerous weapons of war. And you must go to jury duty when called.
My time rolled around to serve on jury duty recently, and unlike past times when I was called, this time I had no real excuse for not serving, and this time, I wanted to serve. In the past, as the leader of a not-for-profit organization, there would have been some inconvenience if I had been chosen to serve, but I never got to the point where my inconvenience was a reason for being excused. All the previous times I was excused was because I knew someone, I had some relationship with the company involved in the case, or I had a person close to me who had a similar bad experience as the plaintiff.
