no country for old men opening analysis

The opening to "no country for old men" starts with sceneic shots of the location this tell the audience were the events will take place. The location its self is a very barren and empty place. the voice over is brilliantly written and performed. He tells us about his life, past and what it means to be a cop in that area and how he was facinated by the men who came before him and lern from them. then he tells us how he had to sent someone to the eltric chair and how the media trys to make the criminal sound diffrent to how it is and the crimnal actuly told him how it was and that he do it agene if given the chance and he would go to hell for it. he also says how you have to be willing to die to do the job and put your soul in hazard and just say okay ill be apart of it. this tells us that the charcter has seen and exprienced things that could break people down and that he is strong willed and has a good moral code he lives by. We also see an arrest happening were it sets up the film, who is the man beaing arrested? why is he beaing arested?
