As personifications of science, the ultimate voyeur, the CSIs in Las Vegas use its superhuman eyes and technological gaze to penetrate all textures and alibis. However, in the process of revealing their scientific truth, the CSIs cannot help revealing themselves and their own secrets. This expands the intrinsically voyeuristic television experience. The viewer not only watches the scientists dissect the bodies and minds of the victims and criminals, but also scrutinizes the CSIs' minds at work. This results in a double voyeurism for the television viewer as now it is the scientists themselves that are on display. Thus, the question "Who are you?" as posed in the series' theme song becomes not only that of the scientists as they try to unveil who the murderers and victims are, but also the theme song of the television viewer who is trying to dis-cover who the CSI men and women really are.
