so this guy goes for a walk

Ray Bradbury has written a story about a guy that goes out for a walk, but in the future.  So he goes to take a walk, a police car pulls him over, he sees there is no police officer in the car and he gets in and leaves.  In his experience in real life, he was stopped by police officers for walking, same thing that happens in the story.  The story though gives a descriptive depiction of what he felt had happened.
