[narrating] I'm a prosecutor. I'm part of the business of accusing, judging and punishing. I explore the evidence of a crime and determine who is charged, who is brought to this room to be tried before his peers. I present my evidence to the jury and they deliberate upon it. They must determine what really happened. If they cannot, we will not know whether the accused deserves to be freed or should be punished. If they cannot find the truth, what is our hope of justice?
