If I were David Mills, I do not have regret to leave Springfield and work in a big city. Although his wife, Tracy wants to stay in Springfield, there are lots of noise, dirt and crime in the city. Even in her sleep she worries because she feel there is not safe in the city. However, I think Mills is very happy to work with Somerset since Somerset has become a homicide detective for twenty-three years and he has enriched experience with investigating different types of cases. Therefore, he can learn and understand how to be a perfect homicide detective on him. Besides, if I were the judge, I would still send Mills to prison. Since he had killed one man, even the man who is a serious killer and kill lots of people. He should send the killer, John Doe to prison to accept sanctions and not to shoot him. If you shoot him, I think your method do not have too difference with the killer, John Doe in the novel, don’t it? You should give him a chance to think about and correct the mistakes. And I think Somerset tell Mills to throw down his gun because he wants that Mills inherits his job to take a responsibility to fight the fight in the city. Then, he can retire and leave the city to have a child with somebody in the country. When Mills leaves prison, I think he will go to visit his wife and baby's grave and talk about his life in prison with them. Also, he prefers to be a detective rather than a policeman because he feels guilty about the past when he was a policeman. And he can have unrestricted investigation when he becomes a detective.
