The Broken Windows theory proposes that visible signs of disorder and crime in a neighborhood, such as broken windows left unrepaired, encourage further disorder and more serious crimes. The theory was first introduced in 1982 by George Kelling and James Wilson. While the theory influenced policing strategies focusing on minor crimes and disorder, there is debate around its effectiveness and whether it unfairly targets low-income and minority communities. Both supporters and critics continue to discuss the impacts and implications of the Broken Windows theory.
