The trouble in America brewed for decades until it finally flashed over into violent riots in the summer of 2016. The elections were postponed indefinitely. After martial law, civil war, and then a brief and destructive world war... America began to pick up the pieces and rebuild. This time, the focus was on equality for all. The cops and drones of the Equality Enforcement Corps would make sure that citizens treated each other fairly.
By 2043, the new government had established financial and social equality, and had nearly eliminated violent crime. Its next goal was to identify currently law-abiding young citizens at risk of becoming the criminals and sociopaths of tomorrow. If they could find them, they believed they could fix them.
