Why do you think Capote split the narrative into sections?

Capote's choice of narrative technique, which essentially consists of two different points of view, allows for different perceptions of events and characters. For the most part, Capote chose the third-person point of view, using an omnisicent narrator. For the more personal sections, he chose to use the first person with a variety of narrators. In doing this, he lends a sense of urgency to the story, and the reader sees the events unfold through the eyes of actual witnesses.
