Im sorry when I replied before to this post, I went on a tangent. I wanted to also say I agree with you here that there is room for improvement in general courtroom understanding for a jury.
They just kind of throw everyone in there and for lots of people it is all new and confusing.
Maybe a training session rather than a quiz. Maybe like Juror Training 101 sessions are needed once a jury pool is decided on.
When I was called in for jury duty, I was surprised find myself in a room with hundreds of other potential jurors. I piqued my curiosity and made me wonder what kind of a case it was (not many high profile cases here). I was also a bit surprised that before doing anything else, we were all required to watch a rather long video about jury service, inc. basics about how the proceedings work, what to expect, the admonition stuff, and FAQs. It was interesting and helpful stuff.
I may have one of a very few who were disappointed to learn that while we were watching the video a plea agreement had been reached so we were all sent home. Boo! In my county those few hours that day still counted as jury duty so I won't be called back for at least 8 years.
