I grew up in Australia where a jury consists of 12 people. I've lived in France for the last 12 years, though, and here the jury (when there is one) it will typically be either 6 or 9 citizens. One of the overseas territories uses a jury system that only has 4 people, and then expands to 6 on appeal. It would be interesting to understand how the 'Anglo Saxon' system (outside of Scotland, it seems) settled on 12 people.
