Reporting what actually went on is an act of creation. Any good story requires detective work, something that is based a lot on intuition, interpersonal communication, and lateral thinking. These skills are not easy to automate. Also, you'll never get the complete story, some guesswork and logic is required to fill in the holes and deliver a cohesive narrative. So in that sense you'd need quite the impressive program to uncover the truth behind, for example, watergate.
