Spurred in part by a 2021 grant from the Bureau of Justice Assistance (BJA BWCPIP Grant # 15P BJA-21-GG-04437-BWCX), Missouri’s St. Louis County Police Department (SLCPD) expanded and refined its body-worn camera (BWC) program, acquiring an additional 100 BWCs to expand deployment to all sworn personnel. Concurrently, SLCPD developed helpful applications around their BWCs, integrating cameras from multiple sources into one readily accessible platform. Overall, the officers at SLCPD who spoke to CNA during a site visit in October 2022 feel the BWC system makes their jobs easier and increases personal safety. Department investment in the technical infrastructure as well as staff resources has allowed creative uses of the cameras and their data with practical results. Commitment and support from both the officers and the department leadership has led to a successful deployment of the camera systems. The integration of BWCs with automated license plate readers (ALPRs), Missouri Department of Transportation highway cameras, and other sources allows users to access video data from multiple sources. This integrated system, managed by the SLCPD Camera Systems Unit (CSU), turns SLCPD’s BWC system into an application that improves operations, efficiency, and officer safety. While automation helps efficiency in the field, the technology still adds labor hours and costs to handle the processing and storage of footage. According to SLCPD, the benefit of increased officer safety and the evidentiary value of BWCs are worth the operational and maintenance costs. The BWCs and their features have been used in several critical incidents to date. The footage often makes investigations more efficient because of the added digital evidence and saves time spent testifying in court. SLCPD has also used BWC footage in press releases, highlighting officers’ actions in the field.

  In less than a decade, body-worn cameras rose from rarity to standard amongst local law enforcement in the U.S. as agencies sought to enhance trust, transparency, and accountability of officers. However, this policing tool also generates large quantities of a new source of data for criminal courts: footage of criminal defendants. This data can provide evidence pertinent to a criminal case, but at a cost of attorney time. Using rich case data from Virginia state courts from 2006-2020 and a new body-worn camera data set I investigate whether local law enforcement adoption of body-worn cameras changes court filings, criminal case dispositions, time to disposition, and other case outcomes. I find evidence that body-worn cameras affect interactions between police and members of the public, but that these effects are restricted to a small subset of cases. Once cases enter the courts, I find that in the aggregate, contrary to expectations, both case processes and resolutions are unresponsive to the influx of data generated by body-worn camera footage.

The U.S. Department of Justice has dedicated $20 million to fund the purchase of and technical assistance for BWCs. In 2013, the Law Enforcement Management and Administrative Statistics survey estimated that about a third of local law enforcement agencies had already adopted BWCs, and this percentage has likely greatly increased since then. 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.…what research questions and types of research should be pursued and why? How can we build a translatable knowledge base that is responsive and rigorous? An important first step in answering these questions is to identify not only existing knowledge but also current projects underway to see research gaps and opportunities. Equally important in building the evidence-base for BWCs is ensuring that research is responsive to the needs and concerns of police and citizens and that it also anticipates future uses and concerns of BWCs. Many types of research might be needed, including process and outcome evaluations, national surveys on prevalence and use, studies about the possible consequences of that implementation for both.

This report provides research findings from a rapid research project reviewing the use of Body-Worn Video (BWV) cameras in a policing context, with specific reference to police-citizen interactions and scrutiny mechanisms. The research was conducted in November and December 2021, using a methodology consisting of a literature review and a sequence of semi-structured interview with BWV experts. The research was undertaken with a view to providing advice and guidance to Police Scotland for the potential widespread future roll-out of BWV in Scotland. It is evident, from the research reviewed here, that BWV is being deployed internationally by law enforcement agencies and other public service providers. Typically, BWV is recognised to provide evidence of incidents, provide a level of personal protection and increased transparency in policing. The rationale for the use of BWV in policing is well established and is afforded a good level of public support. It is also evident, that across UK police forces there is differentiated use of the technology and associated governance mechanisms. In this respect, Police Scotland is in an advantageous position in that it can learn from what is perceived to be ‘best practice’ elsewhere in the UK and beyond. It is apparent that across the UK there are novel emergent mechanisms used to govern BWV in relation to scrutiny and accountability. These include dedicated Scrutiny Panels and practices referred to as random ‘dip sampling’, as well as dedicated codes of practice and use protocols. Here, it is suggested that Police Scotland review what other police forces are doing in this area and design processes that are compatible with Police Scotland’s institutional arrangements. The research presented here also suggests that BWV use protocols and data management procedures are established prior to the widespread deployment of the technology. One aspect in which published literature was lacking was in relation to the impacts of BWV on minority groups and ethnic minorities. Here, the evidence is mixed with some authors claiming BWV strained community relations, whilst others claimed BWV made police interactions more transparent. This points to both, a need for further research, plus the use of caution in the use of BWV in certain situations. It is also noted, that whilst there is a general level of public support for BWV, this relates primarily to basic BWV camera units and that this level of support cannot be assumed from more sophisticated data processes, such as those associated with face recognition and live streaming technologies. Here, it is recommended that Police Scotland implement mechanisms that ensure a degree of oversight and accountability in how BWV cameras are used. This can ensure legitimacy of use and facilitate public confidence in the use of the technology.
