Criminal justice infrastructure varies from country to country. Germany, for example, has a centralized approach that places a higher value on rehabilitation than retribution. In contrast, China has a more decentralized system heavily reliant on mandatory minimum sentences. The American system relies on “common law,” which is derived from UK law to a large extent and is based on legal precedents of previous court rulings. Ultimately, the criminal justice system is a complex institution that will keep evolving in the years to come.
