FOR OVER TWO DECADES, the shows in the Law and Order franchise have been popular with television viewers. Each episode transports viewers into the world of American criminal law and process. A crime, investigation, and judicial process are neatly wrapped in a 1-hour episode, from the dramatic opening theme song with its scene-changing “clang” sound, to the final scene when justice is served. Law and Order episodes focus on criminal law, which is one aspect of the American legal system.

This chapter provides a high-level overview of the legal system in the United States. It is important for Americans to have a general understanding of this system because it affects us every day. We are bound by a system of laws that regulate our behavior and contribute to an ordered society. Laws reflect our values, and they evolve over time.

The American legal system, its history, and its processes are a fascinating area of study. Many talented judges, attorneys, and law scholars have written excellent books about it. This chapter provides only an overview, but will outline a framework that can enable you to do further reading and research on this topic.
