PC Andrew Harper was a hero. He risked his life to keep us safe. The 28-year-old lost it in the line of duty after being dragged behind a car for more than a mile. His injuries were so catastrophic a colleague at the scene couldn’t recognise him. His new bride became a widow within a month of their wedding. Now two of the men responsible for PC Harper’s death (seen here) are set to walk free at the halfway point of their sentences. Harper’s Law already exists. It was passed in Andrew’s name to ensure those who kill emergency workers face tougher sentences. But it doesn’t apply retrospectively. If the law named after Andrew Harper can’t prevent the men responsible for his death being released this early, what was it for? Read the room, prime minister.
