Crime Prevention
Broken Windows Theory
Definition: A criminological theory that visible signs of disorder and neglect (like broken windows) encourage further crime and anti-social behavior.
In Detail
Broken windows theory, introduced by social scientists James Q. Wilson and George L. Kelling in a 1982 Atlantic article, posits that visible signs of crime, disorder, and civil neglect, such as broken windows, graffiti, litter, and vandalism, create an environment that encourages further crime and increasingly serious offenses. The theory suggests a causal chain: untended disorder signals that no one is watching or cares, which emboldens minor offenders, which leads to more serious criminals moving in, which drives out law-abiding residents and businesses, creating a downward spiral. The theory had enormous influence on policing in the 1990s, most notably in New York City under Police Commissioner William Bratton and Mayor Rudolph Giuliani, who implemented aggressive "quality of life" policing targeting minor offenses like fare evasion, public urination, and squeegee men. New York's dramatic crime decline in the 1990s was partly attributed to this approach, though critics argue that crime declined nationally during this period due to other factors (demographics, economic growth, the end of the crack epidemic, increased incarceration). The theory remains controversial. Supporters point to evidence that addressing disorder can prevent more serious crime. Critics argue that broken windows policing disproportionately targets minority and low-income communities, leading to over-policing, erosion of trust, and civil liberties concerns without necessarily reducing serious crime. Modern approaches tend to blend environmental maintenance with community engagement rather than relying solely on aggressive enforcement of minor offenses.
