Final answer:
Traditional criminal offenses like murder, theft, and arson are defined by statutory law and usually tried at the state level in the jurisdiction where they occurred, with the judicial system overseeing the trials.
Step-by-step explanation:
Most traditional criminal offenses such as murder, theft, and arson are defined by statutory law and are tried within the criminal justice system of a specific jurisdiction, typically at the state level. These offenses are generally codified in criminal or penal codes that provide the legal framework for what constitutes a crime, the necessary elements of each offense, and the potential penalties upon conviction. The role of interpreting these laws and overseeing trials falls to the judicial system where judges and juries determine the guilt or innocence of individuals based on the evidence presented.
