First Scientific Report Suggests Body-Cameras Can Prevent Excessive Use Of Force By Police

As President Obama pledges investment in body-worn-camera technology for police officers in the midst of nationwide protests against police violence, researchers say cameras induce ‘self-awareness’ that can prevent unacceptable uses-of-force seen to have tragic consequences in the U.S. over the past year — from New York to Ferguson — but warn that cameras have implications for prosecution and data storage.

Researchers from the University of Cambridge’s Institute of Criminology (IoC) have now published the first full scientific study of the landmark crime experiment they conducted on policing with body-worn-cameras in Rialto, California in 2012 — the results of which have been cited by police departments around the world as the evidentiary basis for rolling out this technology.

The experiment showed that evidence capture is just one output of body-worn video, and the technology is perhaps most effective at actually preventing escalation during police-public interactions — whether that’s abusive behavior towards police or unnecessary use-of-force by police.

The researchers say the knowledge that events are being recorded creates “self-awareness” in all participants during police interactions. This is the critical component that turns body-worn video into a ‘preventative treatment’, causing individuals to modify their behavior in response to an awareness of ‘third-party’ surveillance by cameras acting as a proxy for legal courts — as well as courts of public opinion — should unacceptable behavior take place.

During the 12-month Rialto experiment, use-of-force by officers wearing cameras fell by 59 percent and reports against officers dropped by 87 percent against the previous year’s figures.

However, the research team caution that the Rialto experiment is only the first step on a long road of evidence-gathering, and that more needs to be known about the impact of body-worn cameras in policing before departments are “steamrolled” into adopting the technology — with vital questions remaining about how normalizing the provision of digital video as evidence will affect prosecution expectations, as well as the storage technology and policies that will be required for the enormous amount of data captured.

Self-awareness and deterrent effects of body-cameras

President Obama recently promised to spend $263m of federal funds on body-worn-video in an effort to stem the hemorrhaging legitimacy of U.S. police forces among communities across the United States after the killing of several unarmed black men by police caused nationwide anguish, igniting waves of protest.

Still, some question the merit of camera technology given that the officer responsible for killing Eric Garner — a 43-year-old black man suffocated during an arrest for selling untaxed cigarettes — was acquitted by a grand jury despite the fact that a bystander filmed the altercation on a mobile phone, with footage showing an illegal ‘chokehold’ administered on Garner who repeatedly states: “I can’t breathe.” (A medical examiner ruled the death a homicide). In what many described as the ultimate injustice, the only person indicted by a grand jury in Garner’s death was the bystander who filmed it.

Body cameras may act as a preventative measure, potentially deterring some incidents of excessive force before they take place.

Body cameras may act as a preventative measure by stopping some incidents of excessive use of force before they take place.

For the Cambridge researchers, the Rialto results suggest that body-worn-cameras can mitigate the need for such evidence by preventing this excessive use-of-force in the first place. Data from the Rialto experiment shows police officers are deterred from unacceptable uses-of-force — indeed, from using force in general — by the awareness that an interaction is being filmed; but this ‘deterrence’ relies on cognition of surveillance.

While the evidence provided by the video of Garner’s death would suggest a heinous miscarriage of justice, say researchers, the filming itself by a bystander would not generate the self-awareness and consequent behavior modification during the incident as observed during Rialto’s institutionalized camera use.

“The ‘preventative treatment’ of body-worn-video is the combination of the camera plus both the warning and cognition of the fact that the encounter is being filmed. In the tragic case of Eric Garner, police weren’t aware of the camera and didn’t have to tell the suspect that he, and therefore they, were being filmed,” said Dr. Barak Ariel, from the Cambridge’s IoC, who conducted the crime experiment with Cambridge colleague Dr. Alex Sutherland and Rialto police chief Tony Farrar.

“With institutionalized body-worn-camera use, an officer is obliged to issue a warning from the start that an encounter is being filmed, impacting the psyche of all involved by conveying a straightforward, pragmatic message: we are all being watched, videotaped and expected to follow the rules,” he said.

Rialto findings prompt widespread policy changes

The idea behind body-worn-video, in which small high-definition cameras are strapped to a police officers’ torso or hat, is that every step of every police-public interaction — from the mundane to those involving deadly force — gets recorded to capture the closest approximation of actual events for evidence purposes, with only case-relevant data being stored.

“Police subcultures of illegitimate force responses are likely to be affected by the cameras, because misconduct cannot go undetected — an external set of behavioral norms is being applied and enforced through the cameras. Police-public encounters become more transparent and the curtain of silence that protects misconduct can more easily be unveiled, which makes misconduct less likely,” said Dr. Ariel.

Requiring police offers to wear body cameras led to fewer complaints against police an

Requiring police offers to wear body cameras was found to reduce both use-of-force incidents and complaints against police officers.

In Rialto, an experimental model was defined in which all police shifts over the course of a year were randomly assigned to be either experimental (with camera) or control (without camera), encompassing over 50,000 hours of police-public interactions. The analysis showed that police use-of-force was 2.5 times higher before the cameras were introduced, while complaints against officers dropped from 0.7 complaints per 1,000 contacts to 0.07 per 1,000 contacts.

The dramatic reduction in both use-of-force incidents and complaints against the police during the experiment led to Rialto PD implementing an initial three-year plan for body-worn cameras. When the police force released the results, they were held up by police departments, media and governments in various nations as the rationale for camera technology to be integrated into policing.

Dr. Ariel and colleagues are currently replicating the Rialto experiment with over 30 forces across the world, from the West Yorkshire force and Northern Ireland’s PSNI in the UK to forces in the United States and Uruguay, and aim to announce new findings at the IoC’s Conference for Evidence-Based Policing in July 2015. Early signs match the Rialto success, showing that body-worn-cameras do appear to have significant positive impact on interactions between officers and civilians.

Use of body-cameras poses new challenges

The researchers caution, however, that more research is required, and urge police forces considering implementing body-worn-cameras to contact them for guidance on setting up similar experiments. “Rialto is but one experiment; before this policy is considered more widely, police forces, governments and researchers should invest further time and effort in replicating these findings,” said Dr. Sutherland.

Body-worn cameras appear to be highly cost-effective: analysis from Rialto showed every dollar spent on the cameras saved about four dollars on complaints litigations, and the technology is becoming ever cheaper. However, the sheer levels of data storage required as the cameras are increasingly adopted has the potential to become crippling.

“The velocity and volume of data accumulating in police departments — even if only a fraction of recorded events turn into ‘downloadable’ recordings for evidentiary purposes — will exponentially grow over time,” said Dr. Ariel. “User licenses, storage space, ‘security costs’, maintenance and system upgrades can potentially translate into billions of dollars worldwide.”

Although these initial findings are encouraging, the researchers caution that body-cameras cannot be expected to solve long-standing problems of

Although these initial findings are encouraging, the researchers caution that body-cameras are not flawless and will likely present new challenges that should be considered before the use of body-cameras is adopted by police nationwide.

And, if body-worn cameras become the norm, what might the cost be when video evidence isn’t available? “Historically, courtroom testimonies of response officers have carried tremendous weight, but prevalence of video might lead to reluctance to prosecute when there is no evidence from body-worn-cameras to corroborate the testimony of an officer, or even a victim,” said Dr. Ariel.

There are also there are still plenty of concerns from both the law enforcement and civil rights communities about how, exactly, a large-scale police camera program would be implemented. Which interactions, for example, would be recorded? How would the review process work? What would the penalties be for failing to record an interaction? Such questions are further complicated by state laws that differ on when and where people may be recorded, as well as how such recordings may be stored and accessed by the public.

These problems were highlighted last week in Berkley, Missouri, where 18-year-old Antonio Martin was shot and killed by a police officer who was not wearing his department-issued body camera at the time of the incident. The police officer, who also failed to activate the dashboard camera in his vehicle, claims that Martin pointed a gun at him, but some bystanders have called his account into question. So far, police have not announced any plans to discipline the officer for not following the department policy.

“Body-worn-video has the potential to improve police legitimacy and enhance democracy, not least by calming situations on the front line of policing to prevent the pain and damage caused by unnecessary escalations of volatile situations,” said Dr. Ariel. “But there are substantial effects of body-worn-video that can potentially offset the benefits which future research needs to explore.”
