All nations within the Anglosphere (US, UK, CA, AU & NZ) have JD imposed towards citizens. I know that the US & Canada both inherited that from Britain, which explains why they have it. However, should it be entirely only the judge making the conviction (some countries operate on a lay-judge system meaning juries aren’t used, such as Finland or Japan for example) rather than leaving that decision up to jurors?
We have Schöffen that supposedly bridge the gap between ‘the people’ and the court. That’s a slightly different system though and they only participate in like 10-15% of court cases iirc.
