Jury nullification is a very important fact that I think everyone should know about. We had a case involving it a few years ago in Colorado, the lady from the jury was accused of lying on the forms the jurists had to fill out, it was eventually dismissed.
As I understand it, it was used heavily prior to the Civil War. Evidently, many states had laws that forbid helping slaves find their way north to freedom. Many people were caught red-handed and found not guilty by a jury of their peers, law or no law.
Sometimes, there is still justice in the world.
