It is the year 2097, and advances in nanotechnology have transformed humanity’s ability to study the human brain. Scientists have developed neural nanobots, microscopic machines capable of entering the brain and mapping the physical changes created when a person experiences an event. Once activated, these nanobots analyze neural patterns and reconstruct memories, allowing a person’s perception of a specific moment to be visualized with extraordinary detail, including what they saw, heard, felt, and understood.
Under this system, criminal investigations no longer rely primarily on witness testimony, physical evidence, or interrogations. When a crime occurs, trained investigators implant specialized nanobots into the brains of victims, witnesses, and suspects. The nanobots extract relevant memory sequences connected to the event and convert them into a digital reconstruction that can be reviewed by judges and legal experts. Criminal trials are replaced by memory examinations, where reconstructed experiences become the primary source of evidence used to determine responsibility.
