@clintflint - I don't see why, unless they've got something important on at the same time. I'd love to do jury duty. I think it would just be such a different experience from everyday life, and different is always good.
It might also be because I'm a writer and I'd like to know what jury duty is like in case I want to write a story with it someday. I know my grandfather, who was a lawyer, always wanted to do jury duty to see it from the inside as well. I'm not sure if people in the legal profession are allowed to though.
