Prosecutorial and Public Defender Perceptions: Anticipated Impact of Police Body Worn Cameras on Jurors' Decision Making

O. Nicholas Robertson, John D. McCluskey, Shakierah S. Smith, Craig D. Uchida, and Damon Mosler

This research studies how prosecutors and public defenders (PDs) in three counties adapt to body-worn cameras (BWCs) in their everyday practice and the perceived value of BWC video as evidence in their cases. More specifically, the researchers consider prosecutorial and PD notions regarding the effect of BWC footage on jurors’ expectations and the effect of BWCs on juror decision making. The resulting article reviews the literature with a focus on decision making, the role uncertainty plays in negotiation, and how new evidence, such as the CSI effect (unrealistic citizen/juror expectations about the types and extent of forensic evidence, or in this context, video, available in a criminal case), is anticipated to influence juries and jurors. The CSI effect, resulting from an overwhelming amount of crime television shows, explains the widespread phenomenon of civilians’ misperceptions of the practicality of the criminal justice system. Qualitative results drawn from in-depth interviews inform quantitative analyses from surveys. This is a summary of a larger report, scheduled for release in the coming months.

Stephen Rickman, BWC TTA Lead and Subject Expert

Each jurisdiction and law enforcement agency that deploys body-worn cameras (BWCs) has a unique history, police culture, and circumstances. Community voices, like advocacy and faith-based organizations, police advisory groups, the media, social service organizations, and other community stakeholders, are important to consider when deploying BWCs. In some jurisdictions, these voices have...

Police officers tend to have a love/hate relationship with training. Announce that there will be an Active Shooter Scenario-Based Tactical Training, and some will be giddy while others will dread it.

In View: Body-Worn Camera Compliance

Thomas Woodmansee, Senior Advisor at CNA, BWC subject expert and former police officer, with contributions from BWC experts Orlando Cuevas and Charles Stephenson


When police officers hear or read the word, “compliance” as it relates to policy, what often comes to mind is, “what do I have to do to avoid getting into trouble?” For various reasons, compliance appears to be somewhat more challenging for police agencies when it comes to their body-worn camera (BWC) programs. We are all learning that introducing BWCs entails much...

In View:The Impact of BWCs From a Prosecutor's Perspective

Damon Mosler, Deputy District Attorney, San Diego County, California

Upon learning that a local law enforcement agency was preparing to deploy body-worn cameras (BWCs), we as prosecutors had to wonder what this new evidence would mean to our presentation of cases in court. Would it mean more or less work? More or fewer trials? Better trial outcomes?

In its simplest form, footage from BWCs could be considered just another type of evidence collected by law...

Police cruisers across America; showcase such popular catch phrases as, “To Protect and To Serve” or, “Serving Our Community”.  Perhaps replacing these phrases with a more tangible creed would be appropriate, such as, “Transparency, Accountability, and Officer Compliance.”  With departments racing to outfit their officers with body worn camera’s (BWCs), there are not only concerns about...

Dan Zehnder, Lieutenant for the Las Vegas Metropolitan Police Department & BWC TTA Subject Matter Expert

Body-worn cameras (BWCs) are rapidly being deployed in police departments around the country. These deployments come with a host of expectations, as well as challenges.
