This study examines community policing and insecurity in Keffi Local Government Area of Nasarawa State, Nigeria, through three theoretical lenses: partnership policing and community participation, broken windows, and social disorganization theories. Together, these frameworks stress that policing is most effective when community-driven, preventive, and responsive to underlying social conditions. The partnership approach underscores collaboration and mutual trust between citizens and law enforcement; the broken windows perspective emphasizes addressing minor disorder before it escalates; while social disorganization highlights the impact of weak institutions, unemployment, and instability on crime. A cross-sectional design was adopted, with 355 respondents selected through multi-stage sampling methods. Data were collected using structured questionnaires, in-depth interviews, and secondary sources. Quantitative findings were analyzed with descriptive statistics, while qualitative insights were subjected to content analysis. The Findings of the study revealed that community policing in Keffi has reduced insecurity, particularly where collaboration and intelligence sharing are strong. However, challenges such as corruption, inadequate logistics, poor training, and weak institutional support undermine effectiveness. These findings align with the social disorganization and broken windows perspectives, which link persistent crime to structural weaknesses and unattended minor disorders. The study concludes that community policing remains a vital strategy but requires government support, proper resourcing, and strengthened institutions for sustainability. It recommends improved training, provision of modern policing tools, anticorruption measures, and stronger community–police engagement. Overall, genuine partnership and preventive strategies are key to sustaining community policing as a pathway for reducing insecurity in Keffi and beyond.
