This is actually something I've been wondering about. We don't have this here in Sweden. I've seen this on TV and in movies, jury selections, I mean. Can anyone get summoned, I'm guessing citizens of a certain age? And you have to show up? Or is it considered an honour so everyone just show up because of that? As I've understand it the attorney and the prosecution has a selection of people to pick out the jurors from, and they have a right to say no to a certain amount each, at least that's how I've seen in movies.
Do you get any training for this in school? I mean it's serious things, and people should really know exactly what's expected of them. I wouldn't feel safe if I knew any moron could be on the jury. LOL
Here in Sweden we have a mixture of professional (educated) judges and something that's called "nämndemän", which are a sort of elected laymen in court.
