Learning from the Body-Worn Camera Experience: Evidence-Based Solutions vs. Perceptional Pressure
July 30, 2019 Great article in the recent issue of Police Chief Magazine: Body-Worn Cameras Show Policing Policy Can't Afford to Hide from Evidence by Alex Trouteaud, PhD, Director, Criminal Justice Research, Arnold Ventures. Dr. Trouteaud makes the case, citing the events of 2014 and the subsequent rapid and costly adoption of the fairly new body-worn camera technology, that police agencies should take a different approach in the future. He recommends agencies should express

Digital Evidence Is More Than Just Video
August 1, 2018 A great short article on the importance of effective digital evidence management. The article focuses on storage and management challenges associated with body-worn camera and other types of video. Police departments should, however, anticipate that more and varied types of digital evidence may soon become accepted by our courts. This will require more storage and a more effective, integrated, evidence management tools. Departments should weigh this future stat

November 27, 2017 This morning, in a press conference held at the Las Vegas Metropolitan Police Department Headquarters, CNA publicly released what is perhaps the most important research to date on the efficacy of body-worn cameras in a major police department. The yearlong study, conducted in 2014-2015, followed 400 volunteer officers in a rigorous randomized controlled trial experiment.

Body-Worn Cameras and the Results of Randomized Experiments
November 25, 2017 Great summary by Chip Coldren of CNA. This should be required reading for everyone involved in making procurement, policy and research decisions regarding body-worn cameras. This research is important. How to interpret it is even more important. This summary will be especially useful for those in the media. In View: BWCs and the Results of Randomized Experiments

Body Camera Program Compliance Audits: A Necessity
August 20, 2016 The Louisville Police Department is being criticized for its lack of oversight in conducting "regular, random audits" as required department policy. The article states that the department "isn't keeping track of how the cameras are used." Compliance auditing is an essential program and risk management function. I recently wrote the first part of a series on BWC risk management and use of force for In View on the Body-Worn Camera Training and Technical Assistan

How Software-Defined Storage Improves Access and Sharing For Body Camera Video
August 11, 2016 Much of the activity around police body cameras has focused on getting cameras into the field. However, law enforcement agencies are still trying to identify answers to key questions about how captured videos will be stored, accessed and shared. I was recently interviewed by the Center for Digital Government about how new storage technology is offering agencies a way to choose storage models that best suit their needs while allowing for better use of all store

How Body-Worn Cameras Can Allow Police to Apply a Risk Management Lens to Use of Force
July 6, 2016 This is first in a series of articles I’ve written for “In View” on the CNA Body-Worn Camera Training and Technical Assistance Website: 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

Consultants and Body-Worn Camera Programs
June 25, 2016 This news story is representative of a growing trend that seems to be more common as departments push forward with body-worn camera implementation. Local governments are being asked to commit large amounts of taxpayer dollars or make critical policy and implementation decisions on camera programs. Unfortunately, for both the departments and local officials, they are increasingly discovering “issues” with either the vendor, the equipment, selection processes or

June 17, 2016 A recent report published by Dr. Barak Ariel et al., and now posted on the BJA Body-Worn Camera (BWC) Toolkit website (https://www.bja.gov/bwc/pdfs/BWC-Report.pdf), is already being used by some to question the efficacy of body-worn cameras and the need to implement a program. I urge everyone to read this report carefully especially the Discussion and Conclusions section. A solid BWC policy on activation should start from a position that the camera will always b

What Would Your Department Do?
June 17, 2016 Ask yourself what your department would do if this happened? Was this the improper action of a poorly trained officer? Is this the culture of all patrol officers? Was it an honest mistake? Is department policy clear in this area? Regardless of the answer, departments must have a plan in place to address such shortcomings. The camera will capture much of what officers do on a daily basis in excrutiating detail . Departments now “own” these shortcomings in a way t

The Importance of Body-Worn Camera Tactics
June 17, 2016 This news report highlights the importance of developing sound tactics for the use of body-worn cameras. Officers should be trained to activate their cameras as soon as they are dispatched to a call or prior to officer initiated contacts. Officers should consider activating their cameras prior to their portable radios. Seldom does an officer begin a contact without their radio turned on. This simple “muscle memory” process should become second nature in all bu

Do Body-Worn Cameras Belong in Police Tactical Teams?
April 30, 2016 Body-Worn Cameras are changing the face of policing in America. Almost every police agency in the country has either deployed them, is in the process of deploying them or is exploring their feasibility. What role do they play in what are arguably the most high risk – high liability operations conducted by a police department? Should they be standard issue? When are they activated? Do the activities they record reveal operational sensitive information? What happ
