Answer:
CSI presents its storylines in terms of scientific fact to enhance the credibility of the show and to appeal to viewers who are interested in science and technology. Additionally, presenting forensic techniques as scientific fact may make the show more engaging and captivating for viewers, who may enjoy trying to solve the mysteries along with the characters. However, it is worth noting that the show is a fictional representation of forensic investigation and does not necessarily accurately reflect the complexities of real-life forensic techniques and their interpretation.
