In recent years, the implementation of police body-worn cameras (BWCs) has gained momentum as a tool to enhance transparency, accountability, and trust between law enforcement agencies and the communities they serve. These small, portable devices are typically worn on an officer's uniform and capture audio and video footage of police interactions with the public. In this blog post, we will examine the effects of BWCs on various aspects of policing, including use of force, citizen complaints, and officer perceptions.

Use of force

One primary concern in the debate surrounding the use of BWCs is whether these devices can reduce the instances of excessive or unnecessary force by police officers. Several studies have sought to examine the impact of BWCs on use of force by comparing pre- and post-BWC implementation data.

A 2014 study by the Rialto, California, Police Department found that use of force incidents decreased by 59% in the year following the implementation of BWCs. Similarly, a 2019 study of the Las Vegas Metropolitan Police Department noted a 37% reduction in use of force incidents when officers were wearing BWCs. While these studies suggest a promising trend, it is important to note that other factors, such as changes in police training or department policies, may also contribute to such reductions.

Citizen complaints

In addition to use of force, another major issue in police and community relations is the occurrence of citizen complaints filed against officers. These complaints can stem from a variety of reasons, ranging from alleged police misconduct to dissatisfaction with the response time of officers. BWCs have the potential to both deter undesirable behavior on the part of officers and provide a more accurate account of police-citizen interactions, which can assist in resolving complaints.

A study conducted by the Orlando Police Department in 2014 found that citizen complaints decreased by 65% following the implementation of BWCs. In a similar vein, the Metropolitan Police Department in Washington, D.C., experienced a 17% decrease in citizen complaints in the first year after introducing BWCs.

While these results are promising, it is necessary to consider other factors that may influence the decline in complaints, such as changes in departmental policies or increased awareness and acceptance of the presence of BWCs by both officers and citizens.

Officer perceptions

Equally important to the impact of BWCs on use of force and citizen complaints is the perception of these devices by police officers themselves. Researchers have sought to understand how BWCs influence officer attitudes and behavior, as well as their perceived benefits and drawbacks.

A survey of police officers conducted in a large U.S. city found that the majority of officers believed BWCs would increase their professionalism, improve evidence collection, and ultimately help resolve cases more quickly. However, some officers also expressed concern that the presence of BWCs may inhibit their decision-making ability or deter them from taking necessary action in critical situations.

While officer attitudes toward BWCs may differ, it is important to consider their opinions as agencies consider implementing or expanding BWC programs. Providing proper education, training, and support to officers may help alleviate these concerns and promote a more positive perception of BWCs.

Limitations and future research

Although the research on BWCs is growing, there are several limitations to consider. First, many studies have limited sample sizes, which can hinder the generalizability of results to other jurisdictions. Additionally, due to the relatively recent widespread implementation of BWCs, long-term data is not yet available to evaluate their effects over time.

In order to comprehensively understand the impact of BWCs, future research should examine their effects on a variety of outcomes, such as officer safety, community perceptions of the police, and the judicial process. Longitudinal studies that examine the impact of BWCs over an extended period of time are also vital to understanding their long-term effects.

As the debate surrounding the use of BWCs continues, it is essential that law enforcement agencies, policymakers, and researchers collaborate to better understand their implications both for those who wear them and the citizens they interact with. With this collaborative effort, we can work toward implementing effective BWC programs that foster a more transparent, accountable, and trusting relationship between the police and the communities they serve.
