Bill Robinson is on trial for murder (因谋杀而受审). He grew up in a small town in Ohio and then went to Kent State University for one year. When he was nineteen years old, he was asked to join the army and was soon sent to fight in Vietnam. He was very unhappy there as he hated the war and he hated killing people. Two years later he returned home and tried to pick up where he had left off, but things were never quite the same again for the young black man. For one thing, he always had terrible dreams about the war. He could not concentrate on his studies and soon he had to leave school.Then he was fired from one job after another. He wanted to meet someone nice and get married, but he just couldn't seem to get close to anyone. He was always lonely. Finally one day, while eating at a restaurant, Bill lost control of himself and shot someone for no reason at all. Bill's lawyer hopes that the judge and the jury (陪审团)  will understand that Bill was “temporarily insane" (一时精神错乱) and did not really choose to kill anyone.
