I'm a retired magistrate who sat not only on criminal cases but in the family court and at the Crown Court on appeals. I was called for jury service soon after I was appointed, but in those days, magistrates were not allowed tosit on juries. Now they can, but I have nevet been called again. However, it is not something I would ever recommend, and I would never wish to serve. You never know whether you will be needed, or for how long. There's an awful lot of noring sitting around, when you could be doing something useful. You may get an open-and-shut case, or you may get one that drags on for weeks. You may get a murder trial with harrowing evidence that could haunt you ever after, or a case which is so complicated that it is beyond the wit of a legally-untrained mind. No, stick to watching crime documentaries on tv!
