In View: Key Trends in Body-Worn Camera Policies

The CNA Corporation, Arizona State University (ASU), and Justice and Security Strategies (JSS) provide training and technical assistance (TTA) to law enforcement agencies that have received funding for body-worn cameras (BWCs) through the U.S. Department of Justice, Bureau of Justice Assistance (BJA) BWC Policy and Implementation Program (PIP). Administrative policy review is a central feature of TTA. The TTA team developed a BWC policy review process to assess the comprehensiveness of BWC policies through a BWC Policy Review Scorecard
Because the policy review process assesses comprehensiveness only and is not prescriptive, agencies vary in the way they deal with specific key issues. We recently completed an analysis of the BWC policies for 129 police agencies (covering 54 agencies funded in FY 2015 and 75 in FY 2016). Our analysis examined variation across five dynamic areas: activation, deactivation, citizen notification, officer authority to review, and supervisor authority to review. We examined two additional issues for FY 2016 sites only: camera wearing during off-duty assignments and activation during public demonstrations. The full report can be found online here.  
We identified 17 key BWC policy trends across these 7  policy considerations. They are listed below.
(1) All agencies mandate and prohibit activation for certain types of encounters. No agency allows full officer discretion on BWC activation.
(2) Most agencies (60 percent) allow for discretionary activation under certain circumstances.
(3) All agencies provide guidance for BWC deactivation. However, officer discretion is more common for deactivation than activation.
(4) Officer discretion in the deactivation decision is more common in the policies of FY 2016 agencies. 
Citizen notification
(5) Less than 20 percent of agencies mandate citizen notification of the BWC. 
(6) About 40 percent of agencies recommend, but do not require, citizen notification of the BWC. 
(7) Mandatory notification is less common in the policies of FY 2016 agencies. 
Officer authority to review
(8) Nearly all agencies allow officers to review BWC footage for routine report writing.
(9) Less than 30 percent of agencies allow officers unrestricted access to BWC footage during an administrative investigation.
(10) After a critical incident, more than 90 percent of agencies allow officers to review their BWC footage prior to giving a statement. 
Supervisor authority to review
(11) Nearly all agencies permit supervisors to review BWC footage for administrative purposes, such as investigation of citizen complaints and use of force. 
(12) Most agencies give supervisors authority to review line officers’ BWC footage to determine compliance with BWC policy and procedures. Nearly all FY 2016 agencies (93 percent) allow for BWC policy compliance checks by supervisors.
(13) Most agencies give supervisors authority to review line officers’ BWC footage for general performance evaluation. Nearly all FY 2016 agencies (93 percent) allow supervisors to access BWC footage to assess officer performance. 
Off-duty assignment (FY 2016 only)
(14) The majority of FY 2016 agencies (69 percent) do not address BWC use during off-duty assignments.
(15) Twenty-eight percent of FY 2016 agencies mandate BWC use among officers on off-duty assignments.
Activation during demonstrations (FY 2016 only)
(16) The majority of FY 2016 agencies (71 percent) do not address BWC use during public demonstrations.
(17) Just under 20 percent of FY 2016 agencies require activation and recording during public demonstrations.
Though our sample may not be representative of police agencies nationally, the report provides insights into trends in key policy areas, as well as some benchmarks for agencies involved in BWC policy development and assessment. This analysis reinforces the idea that BWC policy should be responsive to local circumstances, as well as the needs of local stakeholders. Moreover, BWC policies should continue to evolve as evidence from research emerges, as states weigh in with policy requirements, and as BWC technology changes.  

The Critical Importance of Body-Worn Camera Policy Development and Review

This webinar reviewed the key trends identified in our review of over 125 BWC PIP policies.  Administrative policy review is a central feature of TTA. The TTA team developed a BWC policy review process to assess the comprehensiveness of BWC policies through a BWC Policy Review Scorecard. Because the policy review process assesses comprehensiveness only and is not prescriptive, agencies vary in the way they deal with specific key issues. 

In View: What Have We Learned from The BWC Implementation Program So Far?

In FY 2015, the Bureau of Justice Assistance (BJA) funded the Body-Worn Camera (BWC) Training and Technical Assistance (TTA) program to help police agencies and communities implement their BWC Policy Implementation Program (PIP) initiatives and learn lessons from those initiatives for the benefit of other agencies and communities. Since then, the BWC TTA team has responded to over 200 TTA requests, conducted 15 webinars, held 3 regional meetings and 2 national meetings, developed new technical assistance resources, and provided direct technical assistance to over 176 law enforcement agencies across the country.

Through this work, the BWC TTA team has gained a deeper understanding of the complexities and challenges agencies face when implementing a BWC program. Below, we review some of the lessons learned from our BWC PIP agencies over the past two years. These lessons learned should serve as important considerations for agencies just beginning or in the midst of BWC implementation.

1. Have a plan.

As with any new equipment deployment or substantial policy change, agencies must operationally plan how to roll out a BWC program. Planning should be thoughtful, comprehensive, and collaborative, and the plan should include several key factors: identifying program goals, establishing a timeline for deployment, conducting pilot tests, establishing working groups with internal and external representatives, conducting fiscal reviews and preliminary meetings with external stakeholders, reviewing related state legislation, determining staff and technology infrastructure needs, and more (see the BJA BWC Toolkit for guidance on getting started with a BWC program). This planning is fundamental to the implementation process.

2. Be flexible.

Although planning is vital to the successful deployment of BWCs, BWC PIP agencies also stress the importance of remaining flexible throughout the entire implementation process. Plans will change, new state legislation may require policy changes, fiscal changes will occur, equipment may not be as interoperable as promised, and challenges in establishing the infrastructure to support the program will arise. Agencies must be ready to adapt to these uncertainties.

3. Engage internal stakeholders.

Many of the BJA BWC PIP agencies have noted the importance of engaging officers early in the process. Officers should be part of the policy development process, the pilot testing phase, and training development. Actively engaging officers early in the process ensures greater buy-in for the BWC programand greater overall likelihood of success. 

4. Engage external stakeholders.

 BWC programs must also engage external stakeholdersfrom the community, as well as local government and criminal justice partners such as the prosecutor, city manager, and representatives from the local court system. These stakeholders are essential to the success of the program. Agencies should engage them in the process from the very start.

Agencies seeking to implement BWCs should hold multiple meetings with the community to leverage partners such as the NAACP, ACLU, and victims’ advocates. BWC PIP agencies note the importance of seeking input from the community in the policy development phase and being transparent about each phase of the deployment process. Some agencies have tried various methods (e.g., postcards, online surveys, town hall meetings) to inform, engage, and gather input from their communities.

Criminal justice stakeholders are also vital to a BWC program. Prosecutors are, in many ways, an end user of BWC video. Agencies must work closely with prosecutors to create procedures for efficiently and responsibly transfering and sharing BWC video. Prosecutors and police agencies are beginning to understand the effect BWC footage can have on investigations and prosecutions. Working closely with these partners while implementing BWCs results in better processes and fewer challenges with program management.

5. Train.

According to the BWC PIP sites, training is integral to ensuring that officers understand the policy and technology. Training should include related state legislation, how to activate, when or when not to activate, how to catalogue and tag videos, reporting requirements, the limitations of the camera technology, and departmental compliance and auditing.

Furthermore, agencies should consider using BWC footage for training. Agencies like the Las Vegas Metropolitan Police Department, the San Antonio, Texas Police Department, and the Sturgis, Michigan, Police Department frequently use BWC footage to showcase best practices and areas for improved tactics and decision-making skills.The BWC TTA team developed a Training Guide as a resource for law enforcement agencies seeking to develop or modify their BWC training programs. The  guide provides police instructors with a standardized BWC training template that includes an introduction to issues surrounding the development of BWCs, BWC specifications and operations (which vary by vendor), key issues in policy and practice, and topics related to agency accountability.

Agencies should also consider including community representatives in these training sessions or conducting separate training sessions for the media and public. Not only will these sessions encourage transparency and community buy-in, they will also serve as a means for the public to get an up-close look at how police use BWCs in the field.

6. Engage with a research partner.

Though working with a research partner is not a PIP requirement, many funded agencies have engaged with research entities to conduct process evaluations, impact evaluations, or both. Research partners can be a valuable resource during program planning, implementation, and ongoing program management. They can also independently and rigorously assess the BWC program.

7. Audit.

Finally, BWC PIP agencies stress the importance of auditing BWC footage. Once BWCs are deployed, agencies should periodically review and audit videos to ensuring officers use BWCs according to departmental policy. BWC footage can also be used to evaluate performance, highlight training opportunities, and identify areas for department-wide policy and procedure changes.

BWCs and Procedural Justice

This paper explores variations in procedural justice delivered in face to face encounters with citizens before and after the implementation of body worn cameras (BWC). The paper draws on recent advances in the measurement of procedural justice using systematic social observation of police in field settings in the Los Angeles Police Department. Data collected on 555 police citizen encounters are examined in bivariate and multivariate models exploring the primary hypothesis that BWC affects procedural justice delivered by police directly and indirectly.

Body-Worn Camera Policy Implementation Program New Grantee Webinar

This webinar served as an orientation to the FY17 Bureau of Justice Assistance (BJA) Body-Worn Camera Policy Implementation Grant Program. During this webinar, sites heard from BJA and the training and technical assistance (TTA) provider, CNA Corporation. The webinar also familiarized the sites with the goals of the program, the role and value of TTA, provided introductions of the BJA grant administrators, and also gave a brief overview of grant administration requirements. 

BWCs in the Field

In an effort to improve accountability and citizen confidence in the police department,Chief Harteau and the Minneapolis Police Department (MPD), decided to evaluate the use of body worn cameras by officers. Staff researched and a conducted a product search for body worn cameras. Research included the gathering of information on policies, best practices, required infrastructure, devices, costs and operational support.

In View: BWCs and the Results of Randomized Experiments

Recent years have seen a number of new research studies addressing the effects of body-worn cameras (BWCs). Several of these studies implemented randomized controlled designs, the strongest designs available to detect the effect of BWCs with high confidence. Under randomized designs, researchers randomly assign an intervention (in this case, BWCs) to a treatment group of officers (those with BWCs) and a control group of officers (those without BWCs). If they implement the randomization correctly, then there is no real difference between the treatment and control groups, except that one received the intervention (BWCs) and the other did not. As a result, we can confidently attribute any observed differences in the outcomes of interest between these two groups to BWCs.
Somewhat vexing is the fact that these rigorous studies have produced different findings. For example, a study in Rialto, California, found dramatic reductions in use of force incidents and complaints against officers after the introduction of BWCs. [1] Other studies in Mesa, Arizona [2]; Orlando, Florida [3]; Phoenix, Arizona [4]; and Spokane, Washington [5] produced similar findings regarding the direction of the influence of BWCs—use of force incidents and complaints were reduced—but the reductions were not so dramatic. These studies also found positive outcomes regarding citizen approval of BWCs and positive effects of BWCs on citizen views of police legitimacy. More recently, other studies produced different findings. A study in the United Kingdom found increases in assaults on officers wearing BWCs [6], and a recent study of BWCs in the Metropolitan Washington, DC, Police Department [7] found no differences between treatment and control groups regarding use of force incidents and complaints against police.
What are policy-makers and practitioners to make of these different findings, and why do rigorous scientific research designs produce such different findings? Here we provide some suggestions for how to interpret the recent findings on the effects of BWCs. We focus on three important issues: jurisdictional differences in context, contamination in randomized studies, and compliance with BWC policies.
Jurisdictional differences. Rigorous studies of BWCs do not always arrive at the same conclusions about the effects of BWCs because real differences exist among jurisdictions. Simply put, the implementation of BWCs is likely to be different in Rialto, California, and Washington, DC—the communities are different, the histories of police-civilian relationships are different, and the actual implementation of BWCs in each agency might have been different. For example, the implementation of BWCs in Washington, DC occurred after several years of scrutiny and improvements in police operations under a consent decree. This was not the case in Rialto. Thus, it is reasonable to expect more dramatic changes in police-civilian relations after the implementation of BWCs in Rialto than in Washington, where good relations may have already existed. If the baseline frequency of use of force incidents and complaints against police are low at the outset of an experiment with BWCs, large reductions after BWC implementation are less likely.
Contamination. One concern with randomized experiments is the contamination issue, which occurs when members of a control group become exposed to the treatment group intervention such that their behavior becomes more like the members of the treatment group. In the case of BWC experiments, if control group (non-camera-wearing) officers are frequently exposed to treatment group (camera-wearing) officers, the control officers will likely react to the presence of the BWCs and act more like they are wearing BWCs themselves. This occurs, for example, when a camera-wearing and a non-camera-wearing officer arrive at the location of the same call for service. In this instance, the non-camera-wearing officer, if he or she notices the camera-wearing officer (or if the camera-wearing officer lets the other officer know a camera is present), may change his or her behavior during the incident. If such contamination happens often, the conditions of the experiment—separation of the treatment and control group—are lost or diminished, and differences between treatment and control groups will be less likely. In the case of a recent randomized BWC study in Las Vegas, Nevada [8], researchers determined that contamination between treatment and control officers occurred less than 20 percent of the time, and they found significant differences between the groups. In the Washington, DC study, in which differences between treatment and control officers were not found, researchers reported up to 70 percent contamination.[7] Thus, contamination is an important factor to consider when reviewing research results.
Policy compliance. Another important factor to consider when reviewing BWC research results is policy compliance. BWC policies typically provide guidance to officers on when to activate and when to deactivate BWCs, and whether officers are required to (or advised to) inform civilians that the incident is being recorded. If officers are required to turn their cameras on at certain times and notify civilians of the BWC, and they do not do so on regular basis, then there is a noncompliance issue—officers are not routinely following policy. If officers are noncompliant with BWC policy a majority of the time, the conditions of the experiment are again weakened. Either the camera is not operating, or the civilians do not know the camera is present, or both, in which case the hypothesized “civilizing” effect of the camera is negated. Thus, it is possible to implement an experiment with good randomization between treatment and control groups, and low contamination, but lose the desired effects of the cameras as a result of compliance problems. In our work with BWC technical assistance and through our involvement with BWC research, we have seen wide differences in BWC compliance in different jurisdictions— ranging from less than 40 percent compliance in one, to over 90 percent compliance in another. Recently, the Metropolitan Washington, DC, Police Department reported a compliance rate of approximately 65 percent for BWC activation.[9] This too may have contributed to the finding of no differences between treatment and control groups in that study.
We have illustrated several important features of BWC programs and BWC research projects that readers and research consumers should keep in mind when interpreting BWC research results: jurisdictional differences, contamination issues, and compliance issues. To be sure, these are not simple, clear-cut issues. It is possible to have low contamination or low compliance and still find no differences between treatment and control officers, and it is possible to have high contamination and still find differences between treatment and control officers. Even if these factors are well managed and controlled for in BWC research, it is possible that jurisdictional differences (e.g., different use of force and complaint baselines) will drive the research results.
Complexities such as these make clear the need for replication in the sciences. Studies must be done repeatedly under different conditions in different jurisdictions to amass a large body of scientific evidence on which to base decisions and judgements. BWC research has not yet reached this point, though the limited body of evidence in existence points to the conclusion that BWCs are beneficial to the police and their communities. Still, research and analysis must continue, with strong scrutiny of the results, to sort out these confounding issues.

BWC Implementation: Learning from the FY2015 BWC PIP Sites

The U.S. Department of Justice (DOJ), Office of Justice Programs (OJP), Bureau of Justice Assistance (BJA) launched the Body-Worn Camera Policy Implementation Project (PIP) in FY 2015 to assist law enforcement agencies with the enhancement or implementation of Body-Worn Camera (BWC) initiatives. The primary goals of PIP are to improve public safety, reduce crime, and improve public trust between police and the citizens they serve. This webinar showcased the progress and lessons learned from three FY15 BWC PIP sites.

External Stakeholder Perceptions of BWCs

External stakeholders’ acceptance of a police innovation shapes how it spreads and impacts the larger criminal justice system. Therefore, a lack of support among external stakeholders for BWCs can short-circuit their intended benefits. Existing research studies have, however, focused on the implications of BWCs for police officers and the citizens with whom they come into direct contact. As such, there is little direction for agencies concerning the perceptions and concerns about BWCs from others who are affected by a department’s decision to implement a new program.

June 25, 2017 - ICLEA presentation on BWCs

On June 25, 2017, Cheif Ed Book of Santa Fe College and First Sergeant Robert Bleyle of Syracuse University, delivered a presentation on the implementation of body-worn cameras at the IACLEA 59th Annual Conference & Exposition in Milwaukee, Wisconsin. The presentation shared the ins and outs of how to implement a BWC program, including a focus on grant application, policy, equipment, and storage. The speakers also highlighted the resources and sample documents to help ensure alignment with best federal practices.
