At the outset of the story, Anderton immediately defines Witwer by his youth. With his optimism, energy, and faith, Witwer is a foil for paranoid, worn-out Anderton, demonstrating how working in the Precrime system forces a person to become cynical and accustomed to dehumanization. For example, Witwer is instantly uncomfortable when he sees the precogs because he never considered the physical effects of the precog mutation on the people who undergo it. Additionally, Witwer is quick to emphasize that all the people the precogs name would surely commit murder if left to their own devices, while Anderton acknowledges the reality that they could technically be innocent. It’s clear from these early interactions that Witwer’s inexperience with the reality of Precrime allows him to romanticize it, ignoring the complexity inherent in upholding the system. Even toward the very end, Witwer continues to ask Anderton if there is a way to recalibrate the computer or improve the system to create complete surety. Witwer has not quite learned that being Precrime Commissioner means ignoring the possibility of other choices a potential murderer could make.
