Critique and Considerations of the Kansas City Preventive Patrol Experiment


While the Kansas City Preventive Patrol Experiment has been groundbreaking in many ways, it’s important to approach it with a balanced perspective. In this post, we will explore criticisms, limitations, and considerations to bear in mind when interpreting the study.

Methodological Limitations

The experiment was conducted in a specific geographic and temporal context — Kansas City in the early 1970s. This raises questions about the generalizability of the findings to other locations and time periods.

Sample Size and Duration

The study was conducted over a single year and included only 15 police beats. This relatively small sample size and short duration may not provide a comprehensive picture of the long-term effects of different patrol strategies.

Changing Nature of Crime

The types of crime and societal conditions have evolved since the 1970s. New forms of criminal activity, such as cybercrime, were not accounted for in the study, limiting its applicability to modern law enforcement challenges.

Technological Advances

The study predated many technological advancements that are now integral to law enforcement, such as GPS tracking, body cameras, and data analytics. How these tools interact with patrol strategies was not a consideration in the original study.

Unmeasured Variables

While the study did examine several variables like crime rates and public perception, there may have been other factors at play, such as socio-economic conditions or the quality of police-community interactions, which were not measured.

Policy Resistance

Although the study’s findings were revolutionary, they were met with resistance from some law enforcement agencies that were hesitant to change long-standing practices. This highlights the challenges of implementing evidence-based strategies in real-world settings.

Ethical Considerations

Removing police patrols entirely from certain beats, even for experimental purposes, raised ethical questions about the potential risk to those communities.


While the Kansas City Preventive Patrol Experiment has been instrumental in shaping modern policing strategies, it’s crucial to consider its limitations and criticisms. A balanced perspective allows us to appreciate the study’s contributions while acknowledging areas for further research and development.
