B) there can be no appeal or retrial if you are found innocent
Canada also has jury nullification. However our countries differ in that a Canadian prosecutor can appeal the acquittal.
Northern juries found people illegally assisting with the escape of slaves innocent, and southern juries found black lynch mobs innocent. Two very concise, clear examples of jury nullification.
I saw that and thought it was also a good argument in favour of prosecutorial right to appeal.
