The Hero . . .
“...down these mean streets a man must go who is not himself mean, who is neither tarnished nor afraid. He is the hero; he is everything. He must be a complete man and a common man and yet an unusual man. He must be, to use a rather weathered phrase, a man of honor—by instinct, by inevitability, without thought of it, and certainly without saying it. He must be the best man in his world and a good enough man for any world."
Raymond Chandler's definition of a hero
British-American novelist and screenwriter noted for his detective novels
Generally all state and local police are portrayed well in this novel. Any negative law enforcement characters within are imposters or are bad apples with their own agendas or guided by superiors driven by such agendas. Such characters are utilized for dramatic effect and to highlight, by their contrast, the good officers who make up the bulk of such forces.
