Answer:
In the beginning of his argument, Fuller uses logos and pathos to establish what type of person Hinckley is. When describing Hinckley's plan to "become a rock star or a songwriter," he calls it unrealistic. Here, the author uses ethos; the audience must feel some sort of emotions after hearing such a harsh and negative approach at someone else's dreams. But once he explains that this dream wouldn't make sense because he hadn't had, "one moment of training in music," this is where Fuller uses logos and the audience uses their own logic to accept Fuller's argument. He continues using pathos by using negative words to describe Hinckley and even saying that his goals might have been considered "psychotic." Clearly, Fuller wants to make the audience feel how unrealistic and sad Hinckley's goals were to establish a connection in his argument.
