Body-worn cameras are widely used by state and local law enforcement agencies in the United States. They are worn principally by officers in the performance of duties that require open and direct contact with the public. Despite their widespread and growing adoption, the current evidence regarding the effectiveness of body-worn cameras is mixed. Some studies suggest that body-worn cameras may offer benefits while others show either no impact or possible negative effects. The mixed results of these studies strongly imply that additional research is needed. In particular, more studies employing randomized control trials [1] are needed.
Based on these reviews and the existing research on the impact of body-worn cameras use, it is clear that further research is essential to determine the value of body-worn cameras use and potentially the more effective ways body-worn cameras could be deployed. Given the growing use of body-worn cameras, it would be best to build in rigorous evaluations as law enforcement agencies expand their use of this technology.
Developed by the NIJ-funded NLECTC Sensor, Surveillance and Biometric Technologies Center of Excellence, A Primer on Body-Worn Cameras for Law Enforcement provides an introduction to body-worn camera systems. The report discusses the functions and features of body-worn camera systems and highlights issues and factors that law enforcement organizations should consider before and during implementation.
Agencies should consider how body worn cameras will meet their mission needs and requirements prior to procurement and use of the technology. To provide general guidance to law enforcement practitioners, NIJ, NIST and the FBI developed a table listing operating characteristics and associated functionality descriptions based on existing technical resources about criminal justice use of video.[5],[6] The operating characteristics and associated functionality descriptions in the table can help agencies determine what they need as they consider the commercial products available.
VGA, HD 720P, and 1080 HD are predominant standard resolutions. The higher the resolution, the more storage is needed. Estimates below were created assuming H.264 compression with medium to high motion at 30 frames per second (fps) derived using a heuristic formula widely used in industry. Actual storage utilized is dependent on scene complexity and the motion of the video captured. Consider what sort of analysis may be conducted on the video before selecting a resolution. For example, if forensic video analysis is anticipated, a resolution less than VGA is not recommended.

The visuals are shocking: Some show young people running for their lives from a music festival, screaming out in fear as gunfire sprayed. One shows a Palestinian gunman throwing a hand grenade into a public bomb shelter attached to a bus stop, gunning down an unarmed man who ran out; another captured a militant shooting a man in civilian clothes on the ground at point blank range. There were videos of hostages, too, some taken over the border to Gaza: a young Israeli woman begging for mercy on a motorbike; a mother clinging to her two young children; a group of shoeless civilians violently led down a street, their bodies later seen scattered on the ground, crumpled and still.
But shared alongside those videos were falsehoods, too, both subtle and blatant. Some misinformation claiming to be from Israel, Gaza, Lebanon and elsewhere appears intentional: doctored footage, manipulated video, false translations, realistic footage from video games and more. But much seems to be shared unintentionally by journalists, officials and concerned citizens alike. This includes footage from previous conflicts, incorrect geolocation, and false context.
This is where the Digital Investigations Lab at Human Rights Watch comes in, working closely with colleagues in our Middle East and North Africa division as well as our Crisis and Conflict team, including on-the-ground researchers. Since Saturday morning, when the first videos of carnage started trickling in, we have collected, preserved, verified, and contextualized key information to inform our research. We are building investigations into possible war crimes committed in Israel, where people are reeling from the enormity of the loss of life in what is being described as a massacre, and in Gaza, where more than 2.2 million people face a now total siege and near-constant aerial bombardment.
As with all of our research, this is a careful, time-consuming, and often slow process. Given the volume of videos and photos posted online every day, this is an invaluable source of information for our work, but it also means that we regularly collect and analyze several hundred pieces of content for any given piece of research. We are prioritizing the analysis of hundreds of pieces of visual evidence from the present conflict between Israel and armed Palestinian groups in Gaza, which has led to the reported deaths of over 1,200 Israelis and foreigners in Israel, and 1,000 Palestinians since Saturday.
Over the coming weeks and months, we will share our research findings in tandem with on-the-ground researchers. We are just beginning to build a body of evidence to document the unfolding abuses. Our task is to develop a comprehensive picture of the abuses that have occurred and who should be held accountable.
Tallahassee Police Chief Lawrence Revell blasted a report that appeared online with a viral narrated body-camera video alleging an officer "planted" evidence on a man who was arrested on a DUI charge.
The trial of Calvin Riley Sr. began Friday morning, but in an official statement issued Thursday on social media, the police department said it "thoroughly reviewed" the case against him and found no evidence of officer misconduct.
"We are confident with the charges and we respect the judicial process and believe it is vital for a fair trial," the statement said. "Therefore, we will make the full video available for release after the trial has concluded."
Our Tallahassee, a left-leaning and electioneering online outlet founded by Max Herrle, a political operative and former local lobbyist, posted edited video on its website and social media feeds of the May 7, 2023, arrest of Riley. It was viewed more than 2.5 million times on Twitter/X alone.
Herrle, who operates three state political committees and has campaign ties to City Commissioners Jeremy Matlow and Jack Porter and County Commissioner Brian Welch, narrated the footage himself. The two-and-a-half-minute video, with the headline "TPD Officer Plants Evidence in DUI Arrest," shows an officer open a sealed bottle of what is purported to be alcohol, pour it out and throw it back in Riley's car during his arrest.
Revell said it was "reprehensible" that video "intended to sway a jury" was released, and in the way that it was. The Tallahassee Democrat requested a copy of the video before TPD isued its statement.
We are committed to adhering to and enforcing the law while conducting ourselves in an ethical and moral manner," Revell said. "Additionally, we condemn any attempts to manipulate or impede the judicial process as seen with the release of this video. We assure the public that we will continue to do our part to ensure justice is served while upholding the principles of fairness, transparency, and integrity."
The arrest report says Officer Kiersten Oliver stopped Riley after observing his white Mercedes driving around 2 a.m. on South Monroe Street "at a high rate of speed" and with no headlights on. Riley said he had been to Pockets, a local bar, where he'd had a couple of beers. His license was suspended, the report says, and he refused a field sobriety test.
"A search of Riley's vehicle yielded a small (approximately 5 fluid ounces) bottle of vodka that was opened, in a pocket on the driver's seat cover," Officer Margaret Mueth wrote. "Located in the center console of the vehicle I observed there was as cup that smelled of an alcoholic beverage."
Later, while Mueth was taking him to jail, the report says Riley repeated numerous times that TPD "had only arrested him because he had gone to the club and had drinks." Court records show he has a history of citations for driving on a suspended license and other arrests, most more than a decade old.
"The bottle was open because Officer Oliver opened it," the defense motion says. "By engaging in that behavior, Officer Oliver irreparably tainted the stop. Nothing so far has suggested that any of the officers did anything to rectify this action. Rather, they turned off their cameras, arrested Mr. Riley, and handed him over to their partners at the State Attorney's Office for prosecution based on a fundamentally flawed stop and search."
Matlow, who has long been at bitter odds with Revell and management at City Hall, called the footage "troubling to watch" in a post on X and said he will be requesting "a full review and explanation" of the incident by the city manager. He also said TPD's finding of no misconduct "without any explanation of what we can plainly see with our own eyes further strains credulity."
Jones earlier ruled against a defense motion to suppress the bottle from evidence along with several statements Riley made on the other officer's body-worn camera. Both the defense and prosecution stipulated that his refusal to perform field sobriety tests will be excluded and that statements he made after Mueth's attempts to read him his Miranda rights will be admitted.
