The United States Constitution has greatly influenced the U.S. criminal justice system by establishing rights and procedures that guide it. Three key influences are: (1) the principle that no one is above the law, as shown by the trial of President Bill Clinton; (2) the Constitution's ability to adapt to changes in society, seen through its interpretation of racial segregation laws over time; and (3) the right of the accused to be considered innocent until proven guilty. The Constitution continues to shape how criminal justice is administered and will guide changes in the future.
