In criminology, the Broken Windows Theory states that visible signs of crime, antisocial behavior and civil disorder create an urban environment that encourages further crime and disorder, including serious crimes. The theory suggests that policing methods that target minor crimes, such as vandalism, loitering, public drinking and fare evasion, help to create an atmosphere of order and lawfulness.

Vandalism is the action involving deliberate destruction of or damage to public or private property.
