An infraction against the laws of the United States, as codified in the United States Code, constitutes a crime prosecuted by the federal government. Such transgressions often involve activities that cross state lines, impact national security, or concern federal property. For example, bank robbery, counterfeiting, or espionage are considered violations of national law and are therefore adjudicated in the federal court system.
Adherence to these national regulations is essential for maintaining a unified and stable society. Enforcing these laws provides numerous advantages, including safeguarding interstate commerce, protecting national interests, and ensuring equal application of justice across all states. Historically, the definition and scope of these regulations have evolved in response to changing societal needs and emerging threats, reflecting the federal government’s responsibility to address issues beyond the capacity of individual states.
