Criminology

Study of crime, criminal behavior, and the criminal justice system.

Basic Concepts

What is Crime?

Defining Crime

Crime is any act or omission that violates a law and is punishable by the government. Not all bad behavior is a crime—only actions that break specific laws created by society.

Types of Crimes

  • Violent crimes: Actions that use force or threaten harm (e.g., robbery, assault)
  • Property crimes: Involve theft or destruction of property (e.g., burglary, vandalism)
  • White-collar crimes: Non-violent, financially motivated crimes (e.g., fraud, embezzlement)
  • Victimless crimes: No obvious victim, but still against the law (e.g., drug possession)

Changing Definitions

What counts as a crime can change over time and between cultures. For instance, something illegal in one country may be legal in another, and laws can evolve as society changes its attitudes.

Why Study Crime?

Understanding what counts as crime helps society create fair laws, protect citizens, and promote justice.

Examples

  • Speeding on the highway is a crime, but the speed limit may be different in another state.

  • Downloading music without permission is considered a crime in many countries.

In a Nutshell

Crime is a violation of laws defined by society, which can change over time and by location.
