Body-Worn Camera Community Education and Creating Reasonable Expectations

Tom Woodmansee, BWC TTA Senior Advisor at CNA and fomer Police Officer



As more and more police agencies across the country implement body-worn camera (BWC) programs, many feel that it is just a matter of time before this relatively new technology becomes an expected norm for the police. BWC programs have already demonstrated that implementation and outcome expectations are far more complicated and challenging than initially expected. It is difficult to identify another technology or tool that police have adopted which comes with such heightened public expectations and scrutiny. For example, compared to a department’s introduction of an electronic control device, a new caliber of firearm, or an improved records management system, the public clearly has more significant interest in and expectations of BWCs. However, most of the public and media likely lack a comprehensive understanding and appreciation about the limitations of BWCs. Some in the public who express distrust of the police may hope that BWCs will, “hold the police accountable like never before,” while at the same time there are many police officers who are eager to implement BWCs in hopes that they make clear the daily challenges, responsibilities, and decisions that officers face. Both perspectives are fair and may prove to be correct, and the police are in an excellent position to educate their communities about the complexities and realities of BWCs.

Denise Rodriguez, BWC TTA Project Manager and Research Scientist, CNA, Institute for Public Research


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...

In View: BWCs and the Results of Randomized Experiments

James R. "Chip" Coldren, Jr., BWC TTA Director and Managing Director of Justice Programs, CNA, Institute for Public Research

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...
In View: Police Body-Worn Cameras: Perspectives from External Stakeholders

Natalie Todak, Associate Professor, University of Alabama; Janne E. Gaub, Assistant Professor, East Carolina University; and Michael D. White, Associate Director, Arizona State University Center for Violence Prevention and Community Safety 

Changes made within policing carry significant downstream implications for the rest of the criminal justice system and for surrounding communities. The relatively recent expansion in police body-worn camera (BWC) programs across U.S. police agencies represents one such change that will have a wide impact on stakeholders both inside and outside the system. We investigated perceptions of BWCs...

In View: The Impact of BWCs from a Defense Attorney's Perspective

Erika Bierma, Senior Associate at Stafford Rosenbaum LLP, Criminal Defense Attorney in the Eastern & Western Districts of Wisconsin and the United States Court of Appeals for the Seventh Circuit

In the era of Law & Order, NCIS, Criminal Minds, and other television crime dramas, the public now expects clear and compelling recordings that document the commission of an alleged crime. At a minimum, they expect to see recordings of the arrival of the police on the scene and footage of the person charged with committing the crime. Body-worn camera (BWC)...

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...

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

Thomas Woodmansee, Senior Advisor, CNA, and former police officer

A Police Perspective

Perhaps no other new technology in American policing history has created such high expectations of establishing police credibility and accountability as have body-worn cameras (BWCs).  But what impact will such expectations have on investigations and trials? In discussions I have had with law enforcement officers around the country, I have learned that most...

In View: Addressing Police Accountability With BWCs and Victims Privacy

Mai Fernandez, Executive Director of the National Center for Victims of Crime

Although body-worn cameras (BWCs) can increase police accountability, they also can encroach on victim privacy and interfere with confidential communications. BWCs record sensitive information, the public release of which could be emotionally devastating and/or dangerous to a victim. The goal of every police department is to develop BWC policies and procedures that protect a victim’s right to...

In View: The Importance of BWCs from the Chief's Perspective

Harold Medlock, Chief (ret.) Fayetteville, NC and BWC TTA Subject Matter Expert

In summer 2015, my department received a complaint from a citizen that she had been sexually assaulted by one of my officers while the officer cited her for larceny. The complainant would not come to police headquarters, but instead provided her account by phone. The Internal Affairs Commander began an investigation and, two hours later, I learned that the officer was one of three in our...

In View: The Importance of BWCs from the Officer's Perspective

Wayne A Alsup, Research & Planning, San Antonio Police Department

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...

In View: How BWCs Can Be a Risk Management Lens to Use of Force

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. Departments shouldn’t overlook, or underestimate, the simple premise that the day the first BWCs are deployed they begin to document department operations, policy, practices, and training in a detailed manner not previously...

In View:Use of Force Vs. Assaults Against Officers

Michael D. White, Ph.D., Arizona State University, BWC TTA Co-Director

Researchers from the University of Cambridge, RAND Europe, and their colleagues (Ariel et al. 2016a, 2016b) published two papers this week that explore this provocative question. The research designs employed are rigorous, the data are sound, and the results are intriguing. I applaud the researchers for making valuable contributions to the evidence base on body-worn cameras and their impact....
