James "Jim" Nuciforo, a former NYPD detective and actor on Blue Bloods, serves as a consultant for the show, making sure that the police stories depicted are realistic. He works closely with the writers, providing them with insights and stories from his own experience. Nuciforo has taught the actors how to handle guns and even took them to the gun range for lessons. He recently enlisted the help of a "legendary" Texas Ranger for an episode. Despite wanting to keep the show realistic, Nuciforo understands that it ultimately needs to be entertaining.
