Broken windows theory

theory was introduced in a 1982 article by social scientists James Q. Wilson and George L. Kelling

the broken windows theory states that visible signs of crime, anti-social behaviour and civil disorder create an urban environment that encourages further crime and disorder, including serious crimes.

so, it posits that targeting minor crimes such as vandalism, loitering, jaywalking, etc can help to create an atmosphere of order and lawfulness
