What is a crime defined as?

A crime is defined as an act or failure to act that is prohibited by public law. This definition highlights that crimes are established by the legal framework of a society, which outlines specific behaviors deemed unacceptable. Public law serves to maintain order, protect individuals, and ensure the overall safety of the community. By prohibiting certain acts, the law creates boundaries for acceptable behavior and enforces consequences for those who violate these laws.

Understanding this definition underscores the importance of recognizing that crime is not solely about harming others—it's about adhering to laws that govern societal conduct. The other options do not encompass the full legal definition of a crime. For example, a non-violent action causing no harm does not accurately reflect the criteria for a crime, as crimes can include a wide range of actions, including those that do not cause physical harm. Similarly, the legal right to protect oneself pertains to self-defense and does not encompass the broader definition of criminal acts. Lastly, an agreement between parties to avoid prosecution does not constitute a crime but rather a legal strategy to circumvent legal consequences.
