funding father 说，

jury trials prevent tyranny. The definition of tyranny is oppressive power exerted by
the government. Tyranny also exists when absolute power is vested in a single ruler. Jury trials are the opposite of tyranny because the citizens on the jury are given the absolute power to make the final decision. 其实，一切都在法官控制之下。陪审员听什么信息由法官决定，陪审团不过是一个形式而已。参加过的人都知道，如果做不出法庭要的决定，就别回家。如果陪审团的决定和法庭一致，马上结束。
