Kelling et al. (Kelling, George L. & Cohen, Peter A.)

Kelling and Cohen proposed the "broken windows theory" in the 1980s, suggesting that visible signs of disorder, like broken windows or graffiti, lead to increased crime. Their argument is that if minor issues are left unaddressed, it signals that nobody cares, encouraging more serious crime. The theory emphasizes maintaining order in communities to prevent crime before it escalates. Essentially, addressing small problems helps create a safer environment, as people feel more invested in and responsible for their surroundings. This theory has influenced policing strategies and community interventions in urban areas.
