This discussion explores updated research and statistical models and processes to leverage to refine modern policing strategies. By acknowledging concepts like the Pareto Principle, the Law of Crime Concentration, and Binary Percentage Changes, and utilizing frameworks like Process Behavior Charts, Root Cause Analysis, and Decision-Making Management Models, agencies are able to enhance decision-making by operationalizing data to implement targeted strategies and gauge effectiveness through data feedback.

This session’s instructor is Renée J. Mitchell,  the co-founder and president of the American Society of Evidence-Based Policing (ASEBP). She has served in the Sacramento Police Department for 22 years and was a Senior Research Scientist with RTI International.

Specifics of her presentation include:

  • A quick recap of the first installment of the webinar series that demonstrates the inherent flaws and pitfalls of data and its analysis and how it impacts criminal justice agencies.
  • Factors to take into account when reviewing data that emphasize focusing on the officers, their activities, and their locations.
  • The importance of data cleaning to exclude irrelevant data, accurately segment calls for service data, correctly analyze and understand policing patterns, and reflect true public safety issues.
  • Concepts like the Pareto Principle and the Law of Crime Concentration which highlights how interventions must be targeted to the small percentage that creates the most impact on criminality.
  • How effective policing should focus on areas where crime is concentrated using evidence-based interventions.
  • Longitudinal data from Southern Seattle that reveal key crime trajectories and high-incident areas critical for proactive policing.
  • Inadequacies in current data analysis where data is not analyzed effectively to drive decision-making and the need to understand data deeply rather than looking at superficial changes.
  • A look into the default management model where data is reviewed as an afterthought and an updated model that integrates data and feedback to enhance policing strategies and operational effectiveness.
  • The value of process behavior charts in identifying variations and guiding long-term improvements in policing strategies.
  • Operationalizing data effectively by understanding relevant connections between crime and places, persons, and social networks, to enables targeted and effective interventions.
  • Shifting from eminence-based to evidence-based policing by mapping crimes across different time ranges to truly identify trends and taking the stratified approach to problems.
  • Utilizing models like the process flow chart, root cause analysis, and decision-making management models to break down data, stratify problems, get to the root cause, problem-solve, come up with interventions, and leverage a feedback loop to assess effectiveness.

Points raised during the Q&A are about:

  • Understanding what “correlation is not causation” means.
  • The pitfalls of comparing data year over year without considering other variables and why rolling comparisons are able to obtain more accurate insights.
  • Incorporating external events like weather or special events into data analysis to provide context and account for their impact on policing numbers.

Audience Comments

  • “I have no doubt that many agencies have become caught in a belief that Compstat is the only way to pursue crime strategies. My agency has an entire division to handle compstat and it is burdensome and ineffective. I loved listening to some new and researched ways to look at data, and particularly how to parse apart data to understand what is truly actionable.”
  • “A very good webinar.”
  • “Thank you for making this information available.”
  • “Great webinar with information that I can use immediately.”
  • “I appreciate the presentation and the speakers – they spoke clearly and the content was very informative.”
