The Broken Windows Theory proposes that minor crimes and disorder, if left unchecked, can lead to more serious crimes. The theory was developed by James Q. Wilson and George Kelling in 1982. Critics argue that aggressive over-policing of minor offenses based on this theory strains the criminal justice system and burdens impoverished people, while supporters point to reductions in crime rates in areas where it was applied, such as New York City in the 1990s. Debate continues around the theory's validity and impact.
