The Proactive Policing Lab
Cynthia Lum (PI) and Christopher Koper (PI); with Xiaoyun Wu, William Johnson, Megan Stoltz, and Sang Jun Park (Research Assistants) (Funded by the Laura and John Arnold Foundation)
One of the most significant reforms in modern policing has been the push for police to be more proactive, either to reduce crime or to build trust and confidence with citizens. While there have been controversies surrounding certain types of proactivity such as stop-question-and-frisk, pretextual traffic stops, and zero tolerance policing, research continues to find that many other types of proactive approaches (e.g., problem-solving, positive community contacts, and patrol visibility) can be effective in not only preventing crime and disorder but improving citizen satisfaction with the police. However, despite studies evaluating specific proactive interventions, we actually know little about the realities of proactive policing, including the extent to which police officers and agencies in the U.S. are proactive, the types, frequency and dosages of proactivity by officers, and the impacts and consequences of police proactivity. The Proactive Policing Lab was established by professors Lum and Koper within the Center for Evidence-Based Crime Policy at George Mason University to examine these questions.
Basic Analysis of Traffic Citation Data for the Alexandria Police Department 2011-2015
Cynthia Lum and Xiaoyun Wu
At the request of the Alexandria City (VA) Police Department, we conducted an independent and preliminary analysis of the police department’s traffic citation data from 2011-2015.
An Evidence-Assessment of the Recommendations of the President’s Task Force on 21st Century Policing
Cynthia Lum (PI), Christopher Koper (PI), Charlotte Gill (CoPI), Cody Telep, Julie Hibdon, and Laurie Robinson (Faculty Researchers) (Laura and John Arnold Foundation)
The Final Report of the President’s Task Force on 21st Century Policing is one of the most significant documents for law enforcement in modern history. The Task Force was charged by President Obama in 2014 to “examine ways of fostering strong, collaborative relationships between local law enforcement and the communities they protect and to make recommendations to the President on the ways policing practices can promote effective crime reduction while building public trust” (Final Report, p. 5). But where should law enforcement agencies begin in implementing these recommendations? Which recommendations should be prioritized for action, for policy implementation, or for more research? With a grant from the Laura and John Arnold Foundation, the Institute for Community-Police Relations of the International Association of Chiefs of Police (IACP) has collaborated with researchers from George Mason University’s (GMU) Center for Evidence-Based Crime Policy to create an evidence-based Blueprint for 21st Century Policing. The research team was charged with reviewing existing research knowledge about those Task Force recommendations relevant to state and local law enforcement, highlighting promising efforts based on research knowledge, and identifying issues that need more research and testing.
Body Worn Cameras: Knowledge Gaps and Opportunities (completed)
Cynthia Lum (PI), Christopher Koper (PI), Linda Merola (Faculty Researcher), Amber Scherer and Amanda Reioux (Research Assistants) (Laura and John Arnold Foundation)
Recent use-of-force events have led law enforcement agencies, citizens, civil rights groups, city councils, and even the President to push for the rapid adoption of body-worn camera (BWC) technology. In a period of less than a year, BWCs transformed from a technology that received little attention by many police leaders and scholars to one that has become rapidly prioritized, funded, and diffused into local policing. At the same time, this rapid adoption of BWCs is occurring within a low information environment; researchers are only beginning to develop knowledge about the effects, both intentional and unintentional, of this technology. Much more research is needed to understand the intended and unintended impacts and consequences of cameras. In this project, we identify knowledge gaps and opportunities for research on body worn cameras, examine concerns in law enforcement and the courts regarding body worn cameras, and assist in making evidence-informed decisions about this technology. To access all completed reports, go to the Body Worn Camera webpage in our Technology Webportal.
Identifying effective investigative practices: A National Study Using Trajectory Analysis (ongoing)
Cynthia Lum (PI), Charles Wellford (PI), Thomas Scott and Heather Vovak (Laura and John Arnold Foundation)
Most serious violent and property crimes do not result in clearance, and clearance rates for these crime categories have not changed in over thirty years; indeed, for homicide, clearance rates have declined dramatically. Current research on crime clearances leaves many questions unanswered including what police can do to improve clearance rates in a just and respectful manner. Our preliminary examination of UCR data in the last three decades shows that despite significant fluctuations in crime rates, some agencies have maintained high clearance rates for all serious crimes during this period while others have shown a pattern of low clearance or even consistent declines. This study will analyze and understand this variation using trajectory approaches (Nagin), and further identify a sample of agencies that differ in clearance trajectories to explore why some agencies perform better than others.
Evaluating the Crime Control and Cost-Benefit Effectiveness of License Plate Recognition (LPR) Technology (ongoing)
Cynthia Lum (PI), Christopher Koper (PI), James Willis (CoPI), Stephen Happeny, Heather Vovak, and Jordan Nichols (NIJ: 2013-IJ-CX-0017)
This study examines the crime control and cost-effectiveness of the use of license plate readers (LPR) in police agencies. Preliminary assessments of LPR focused on the efficiency of the technology itself, not its crime control or cost-effectiveness. Limited randomized experiments conducted by this study’s PIs in northern Virginia and Mesa, AZ (discussed below) have provided mixed evidence on LPR’s effectiveness in reducing crime and suggest that the impact of LPR use on crime may depend on the scale of LPR deployment, the information and information sharing supporting LPR systems, and the specific ways that LPRs are used. In this study, we explored the effectiveness of LPR in both investigations and patrol, as well as conduct a national survey to assess the diffusion of this innovation.

The Evidence-Based Policing Matrix is a research-to-practice translation tool that categories and visualizes all experimental and quasi-experimental research on police and crime reduction according to three common dimensions of crime prevention – the nature of the target, the extent to which the strategy is proactive or reactive, and the specificity or generality of the strategy. This categorization and visualization of policing evaluation studies reveals three-dimensional clusters of effective studies, which we refer to as “realms of effectiveness.” These realms of effectiveness provide insights into the nature and commonalities of effective police strategies and can be used by police agencies to guide various aspects of their operations.

Improving Police Response to Mental Health Crisis in a Rural Area (ongoing)
Sue-Ming Yang (PI), Charlotte Gill (co-PI), Caitlin Kanewske, Paige St. Clair Thompson
Bureau of Justice Assistance Smart Policing Initiative (with Roanoke County Police Department), 2015-WY-BX-0007, $630,000
Mental health-related calls are a major concern in Roanoke County, as in many police departments around the country. While they account for a small number of calls overall, they disproportionately consume police and mental health service resources. This is especially challenging in a rural department like Roanoke, where services are already limited.CEBCP and RCPD are collaborating to transform RCPD’s current approach to these calls by providing quality mental health service to people with mental illness who have contact with the police. CEBCP and RCPD have partnered with Intercept Youth Service’s Crisis One program to design and implement a standard treatment response. Police will have 24-hour access to on-call trained mental health professionals, who can take over from officers where a mental health issue is identified but the individual does not meet the criteria for arrest or emergency custody. We are evaluating the results of the program in a randomized controlled trial.

Response Awareness, De-escalation, and Referral (RADAR): A Subject-Specific Information-Sharing Approach to Increase Public Safety in First Responder Crisis Management (ongoing)
Charlotte Gill (PI) and Rachel Jensen, with Breanne Cave (co-PI, Police Foundation)
Bureau of Justice Assistance Smart Policing Initiative (with Shoreline Police Department), 2015-WY-BX-0005, $630,000
CEBCP, the Police Foundation, and Shoreline Police Department are collaborating to develop RADAR, a community-focused program that seeks to reduce repeat calls for service and the risk of use-of-force incidents between police and individuals with mental or behavioral health issues and/or developmental disabilities (BH/DD). The RADAR approach involves relationship building between police and individuals with BH/DD and information sharing among first responders to improve emergency response when the individual is in crisis. The goals of the program include developing individualized de-escalation strategies, connecting individuals with BH/DD to existing services and treatment, and promoting police-community collaboration. RADAR will be evaluated using a rigorous quasi-experimental evaluation.

Office of Community Oriented Policing Services, 2012-CK-WX-K026, $250,000
While there is a growing body of research indicating that crime concentrates at small geographic units or ‘hot spots,’ little research has examined the unique characteristics of juvenile offending at places. In this project, funded by the Office of Community Oriented Policing Services, we developed, implemented, and rigorously evaluated a community-oriented policing approach to juvenile crime hot spots in Seattle. The police worked with the community to develop community policing and problem-solving responses targeted at the specific risk factors for juvenile crime in each hot spot. These strategies, while police-led, focused on crime prevention rather than traditional arrest-based law enforcement approaches. Although the police achieved several successes, there was no overall effect on crime in the hot spots. However, the project revealed key lessons for police leaders and jurisdictions seeking to implement community policing, including the importance of organizational support and training for community policing efforts.

Increasing Collective Efficacy at Crime Hot Spots: A Patrol Force Approach in Brooklyn Park, Minnesota (ongoing)

Bureau of Justice Assistance Smart Policing Initiative (with Brooklyn Park Police Department), 2013-DB-BX-0030, $700,000
This project capitalizes on new evidence that indicators of social control, such as collective efficacy, are concentrated at individual street blocks. High collective efficacy is associated with a lower risk of a block becoming a crime hot spot. Traditional hot spots policing approaches rarely account for the social context of crime at places, or the role of the community in crime prevention. In this project, CEBCP and the Brooklyn Park Police Department collaborated to develop a problem-solving approach called BP-ACT (Brooklyn Park-Assets Coming Together to Take Action), in which police first identified “assets” (key residents and community resources) at the hot spots and then brought these resources together to collectively develop solutions to crime problems. The goal of BP-ACT is for the police to help build collective efficacy by bringing communities together to deal with crime and disorder at hot spots. We are evaluating BP-ACT using a randomized controlled trial and expect to have final results by late 2017.

City of Seattle Office of City Auditor, $100,000
Seattle’s City Auditor finds that Seattle Police Department has been “thoughtful in the development” of its School Emphasis Officer (school police) program, seeking to avoid the focus on patrol and enforcement that characterizes some police activity in schools. The program’s website states that the SEOs are “specially selected for their interest and experience in working with youth,” and focus on providing support to at-risk youth through promising approaches such as mentoring and conflict resolution/restorative justice, home visits, and referral to services. However, as with most school police programs, Seattle’s approach has not been evaluated. In this process evaluation we documented the SEO program through analysis of program documentation; interviews with key stakeholders, including the SEOs themselves; and observations of the SEOs working in the schools. We found that the program was implemented in line with a non-law enforcement focus and had good potential for integration with services and enhancement of police-community relations. However, it also faced important challenges, including clarity of the program structure; evaluability; and sustainability. We provided recommendations for clarifying the program with a view toward future rigorous evaluation.

Realizing the Potential of Technology In Policing: A Multisite Study of the Social, Organizational, and Behavioral Aspects of Implementing Policing Technologies. National Institute of Justice Office of Research and Evaluation (completed)
Christopher Koper (PI), Cynthia Lum (PI), James Willis (co-PI), and Julie Hibdon, in collaboration with the Police Executive Research Forum. (NIJ: 2010-MU-MU-0019)
This project examines the social, organizational, and behavioral implications of some of the most commonly used technologies in policing. While technological advances hold great promise for enhancing the effectiveness, fairness, and legitimacy of policing, there has been little research on the implementation and impacts of policing technology, and that which does exist suggests that technology does not always bring expected benefits. There is thus a need to better understand both how technology affects police agencies and how, in turn, various aspects of police agencies and their environments shape the uses and effectiveness of policing technology. This project examined these issues through in-depth cases studies and experiments in four police agencies. Findings from this project can help illuminate the organizational practices and changes needed to fully realize the potential of technology for enhancing the fairness and effectiveness of policing.

The Mobilization of Crime Mapping and Intelligence Gathering: Evaluating Smartphone Deployment and Custom App Development in a Midsize Law Enforcement Agency (completed)
David Weisburd (PI), Charlotte Gill (co-PI), in collaboration with Redlands Police Department (Travis Taniguchi, PI)
National Institute of Justice, 2010-DE-BX-K006, $475,000
Advances in technology, such as smartphones and other mobile devices, provide new opportunities for data-driven law enforcement. CEBCP collaborated with the Redlands, CA Police Department (RPD) and the Omega Group to develop and test an iPhone application that allows police officers to access and record data on hot spots, crime incidents, and people while out on patrol. The research team surveyed officers and civilians within the department to understand their technological capabilities and needs, and evaluated the prototype app in a randomized controlled field experiment.

The security of transportation facilities is of national concern and carries significant costs. Yet, very little evidence exists on what types or processes, programs, and interagency strategies yield the most effective cost-beneficial security structures. Through funding from the Department of Homeland Security, this project examines crime prevention and security in our nation’s airports in a multi-stage evaluation.

Sacramento Police Department Partnership (completed)
Renee Mitchell, Sacramento PD (PI), David Weisburd, Cynthia Lum, Christopher Koper and Cody Telep
Sgt. Renee Mitchell in collaboration with the CEBCP has recently completed a hot spots policing experiment in Sacramento. Sgt. Mitchell undertook this project without any additional funding. The Sacramento Police Department released a press release announcing the significant crime declines that resulted from the experiment: “‘Hot Spots’ Policing Reduces Crime” and the COPS Office also summarized the results from the experiment.

Objectives: This randomized controlled experiment tests whether license plate readers (LPR) deter crime generally, and automobile crime more specifically in crime hot spots. The limited intervention tested here reflects one current likely use of LPR at the time of this publication.
Methods: We use a place-based block randomized experiment. Our subjects were 30 hot spots across two jurisdictions, 15 which were assigned to experimental conditions. The treatment involved targeted police patrols using a “sweep and sit” approach with license plate readers in these hot spots, also applying the Koper Curve timing principle. We examine effects of the intervention during and in a 30-day period post-intervention, controlling for pre-intervention levels of crime, seasonal factors, and jurisdiction.
Results: Our findings indicate that, when small numbers of LPR patrols are used in crime hot spots in the way we have tested them here, they do not seem to generate either a general or offense-specific deterrent effect.
Conclusions: While we did not find significant findings of this intervention, a number of limitations and caveats to this study must be considered in conjunction with these findings. The authors suggest how already acquired LPRs might be used in ways that might increase their effectiveness in crime hot spots.
CEBCP-University of Cambridge Partnership (completed)
Cynthia Lum (PI)
Building an evidence-based policing infrastructure requires that police researchers understand, develop, and participate in activities that facilitate the translation of research to practice. One core component of this participation is finding methods to meaningfully interact with police practitioners in ways that convey research findings and provide opportunities to apply research in practice. The CEBCP-University of Cambridge Partnership pairs the Evidence-Based Research Program with the University of Cambridge, Institute of Criminology, Police Executive Programme (Dr. Lawrence Sherman, Director). Specifically, this grant serves to build the capacity for law enforcement agents in the United Kingdom to become more evidence-based in their daily practices, to improve their education in this area, and to apply their knowledge acquisition in the field. This venture is spearheaded by Dr. Cynthia Lum, co-Director of the Evidence-Based Research Program and fellow collaborators of the Evidence-Based Policing Matrix, Drs. Christopher Koper and Cody Telep.
CEBCP-Association of Prosecuting Attorneys Partnership (completed)
The field of prosecution needs a stronger evidence-base. Researchers within the CEBCP explore this need through a collaboration with the Association of Prosecuting Attorneys. The first project focuses on a research contract on animal abuse. But more generally, the CEBCP and APA hope to begin a relationship in which the area of evidence-based prosecution might be advanced. Drs. Cynthia Lum and Christopher Koper are developing another Matrix – the “Evidence-Based Prosecution Matrix” in this area.
The San Bernardino Valley Broken Windows Policing Experiment (completed)
David Weisburd (PI), Josh Hinkle, Christine Famega, and Justin Ready
Over the last two decades, “Broken Windows Policing” has become a central component of police strategies to combat crime and disorder. But surprisingly, Broken Windows Policing itself has not been subject to sustained empirical examination. In this project, we address this knowledge gap by conducting a randomized, experimental evaluation of Broken Windows Policing in three cities in the San Bernardino Valley area of California. Questions addressed in this study will be whether broken windows policing reduced fear, made residents feel safer, and increased collective community efficacy. This project is being funded by the National Institute of Justice and is conducted in conjunction with researchers at the University of Maryland and California State University, San Bernardino.
The Effects of Problem-Oriented Policing on Crime and Disorder: A Systematic Review (completed)
David Weisburd (PI), Cody Telep, Josh Hinkle, and John Eck
Problem-oriented policing has diffused quickly since Herman Goldstein’s original conception in 1979. Today, more than two-thirds of large police departments utilize POP. In this project, we conducted a Campbell Collaboration systematic review of POP programs to synthesize the extant literature on problem-oriented policing to determine whether this widely adopted innovation is effective in reducing crime and disorder. Eligible studies for this review had to meet rigorous methodological criteria set forth by Campbell . After an exhaustive literature review, only 10 eligible studies were discovered, which indicate that in general, POP does help reduce crime, but our ability to contextualize this finding was limited by the small number of methodologically rigorous studies. An examination of pre/post evaluations of problem-oriented policing indicate this program has much promise.
Final report available here.
The Influence of Places on Policing: The NIJ DuBois Fellowship. (completed)
Cynthia Lum (PI) (NIJ: 2007-IJ-CX-0032)
Do characteristics of places, in particular their racial, ethnic, immigrant, or language composition, influence police decision making?
As the 2007-2008 National Institute of Justice W.E.B. DuBois Fellow, Dr. Lum examines whether police officers “upgrade” or “downgrade” either the seriousness of a call for service or their decision to take further actions (reports, arrests) may be influenced by the characteristics of people who reside at those places. Over 250,000 “decision making pathways” for all crime and across all small spaces in an entire city are analyzed in this study.
Project TIPLINE (completed)
Cynthia Lum (PI)
Project TIPLINE was developed by Dr. Cynthia Lum at George Mason University, in collaboration with the Departments of Justice (NIJ) and Defense (SPAWAR), to provide law enforcement with free tools to develop tip line systems for building their capacity to respond to critical incidents as well as investigative and community-based problem solving projects using large amounts of publically-garnered information. Inspired by lessons learned from the Washington DC tri-state area sniper incident, Project TIPLINE is an automated tip collection, management, andanalytic tool which is adaptable, operationally relevant, practitioner friendly, and technologically efficient. Included with the free software is also an operational handbook designed in consultation with police partners to guide agencies through the process of setting up the automated TIPLINE system and also in developing standard operating procedures, strategies, and tactics for preparing and responding to critical events using large amounts of tips gathered from the public.
