求翻译：从理论上说，在被告被证明有罪之前认为他无罪的观念能确保不判冤案、不冤枉好人。在独幕剧《十二个愤怒的人》中，八号陪审员就是利用这一原则来挽救那个小伙子的性命。是什么意思？

In theory, the defendant is innocent until proven guilty that he can ensure that no sub-concept of injustice, not innocent man. In the one-act play "12 Angry Man", on the 8th of this principle is the use of jurors to save the young man's life.
