In the 2002 sci-fi noir film Minority Report, PreCrime, a specialized police agency, apprehends people who are forecast to commit crimes. No trial is necessary because the not-yet-committed crime is considered a vision of the future and thus a matter of fact. The film's plot challenges viewers to consider the issue of free will vs. determinism, and consequently, the morality of punishing someone for a crime not yet committed. It serves as a useful metaphor for the argument against coercive vaccination, writes Dr. Jeffrey A. Singer. That's because, while some argue that unvaccinated people will endanger the life and health of innocent bystanders, such a position requires infallible precognition.
