The writer has used ethos, as he describes himself as someone who has had firsthand experience in losing a child to an accidental gunshot, and knows what it feels like to have kin killed by gunshots, so he has the right and authority to approach the matter. He has used pathos, by describing how he lost his son and the reason for his appeal to the congressman was in order to decrease the number of such accidents in households so it would not happen to other families and their children. He described how his child was killed by gunfire, which made for emotional appeal. He has used logos, as he gave information on the statistics and numbers related to gun and handgun ownership and the accidents caused by gunshots. This information is given throughout the whole letter and this makes the letter a more logos-driven letter.
