All answers are assigned by State of K users. The label Mixed means that a study found some evidence to indicate that the answer to the question is "yes" and some evidence to indicate that the answer is "no". This label is often applied when a study uses two or more proxies to study the same phenomenon (i.e. firearm sales figures and self-reported firearm ownership rates as proxies for the prevalence of firearms) and the proxies yield different results when looking for correlations with another phenomenon (i.e. firearm-related deaths). Alternatively, the label may be applied if the phenomenon under study (i.e. whether breast milk improves cognitive function) is true for one group, but not another (i.e. true for girls, but not for boys). The label Insuff. Evidence means that a study found there was insufficient evidence to reach a conclusion regarding the question. The label No Data means that State of K wasn't able to identify the study's response to the question based on the information that was available. This label is often applied when the person creating the list does not have access to the full text and the answer isn't clear from the abstract.

All labels of Literature Reviews and Highly Regarded Source are assigned by State of K.

The Benefits of Body-Worn Cameras: New Findings from a Randomized Controlled Trial at the Las Vegas Metropolitan Police Department
"Many community stakeholders and criminal justice leaders have suggested placingbody-worn cameras (BWCs) on police officers improves the civility of police-citizenencounters and enhances citizen perceptions of police transparency and legitimacy. Inresponse, many police departments have adopted this technology to improve thequality of policing in their communities. However, the existing evaluation evidence onthe intended and unintended consequences of outfitting police officers with BWCs isstill developing. This study reports the findings of a randomized controlled trial (RCT)involving more than 400 police officers in the Las Vegas Metropolitan PoliceDepartment (LVMPD). We find that BWC-wearing officers generated significantly fewercomplaints and use of force reports relative to control officers without cameras. BWCwearing officers also made more arrests and issued more citations than their nonBWC-wearing controls. In addition, our cost-benefit analysis revealed that savings fromreduced complaints against officers, and the reduced time required to resolve suchcomplaints, resulted in substantial cost savings for the police department. Consideringthat LVMPD had already introduced reforms regarding use of force through aCollaborative Reform Initiative prior to implementing body worn cameras, thesefindings suggest that body worn cameras can have compelling effects withoutincreasing costs."

Exploring the Potential for Body-Worn Cameras to Reduce Violence in Police–Citizen Encounters
"One of the most compelling perceived benefits of body-worn cameras (BWCs) involves the potential for reductions in citizen complaints and police use of force. A handful of early studies reported significant reductions in both outcomes following BWC adoption, but several recent studies have failed to document such effects. The current study explores this question using data from a randomized controlled trial conducted in the Spokane (WA) Police Department. Approximately half of patrol officers (n = 82) were assigned BWCs in May 2015, while the other half (n = 67) received their BWCs 6 months later (November 2015). The study explores the effects of BWCs on use of force, complaints against officers, and officer injuries, using more than three years of official department data pre- and post-BWC deployment. The outcomes of interest are rare in Spokane, which limited both statistical power and the results from significance testing. However, the within-group trends are consistent with a positive effect, particularly for percent change. Following BWC deployment, the percentage of officers with a complaint in each group declined by 50% and 78% (Control and Treatment, respectively); the percentage of officers with a use of force declined notably (39%) for one group only. The reductions disappeared after 6 months for the Treatment group. There was no relationship between BWCs and officer injuries. The authors discuss the implications of the findings for the ongoing dialogue on BWCs."

Body-worn video: A systematic review of literature
"Law enforcement use of video-based technology has substantially increased over the past decade. This systematic review examines the current evidence base for efficacy of body-worn video and the current case for implementation. Five articles were identified as pertinent to this review from a search of five electronic databases, with a further six articles of grey literature included. Inter-rater reliability was high amongst three independent screeners of literature. Articles were short listed for review if they explicitly identified police and record-ing devices as topic areas. Articles were then excluded if they did not involve an operational trial of body-worn video. Eleven articles were included for review; of the five peer-reviewed studies, two were randomised controlled trials. An abundance of evidence was provided; however, the majority of articles were methodologically weak. Body-worn video was shown to reduce use of force incidents, crime rates for certain crime types and court costs. Public response to body-worn video was varied, as was police officer and public opinion. Due to methodological limitations evident in most studies and the general lack of peer-reviewed material, further research is required; however, there are some considerable benefits reported in the current literature"

A Quasi-Experimental Evaluation of the Effects of Police Body-Worn Cameras (BWCs) on Response-to-Resistance in a Large Metropolitan Police Department
"© 2017 Taylor & Francis Group, LLC. The current study provides a statistically rigorous program evaluation of the impact of police body-worn cameras (BWCs) on police response-to-resistance (e.g., use of force). Results indicate that BWC officers’ mean frequency of response-to-resistance decreased by 8.4% from the 12 months pre-BWC implementation to the 12 months post-BWC implementation compared with a 3.4% increase observed for the matched sample of non-BWC officers. Police departments should consider adopting BWCs alongside other strategies to reduce police response-to-resistance, and to improve transparency and accountability. Study limitations and directions for future research are also discussed."

Testing the effects of police body-worn cameras on use of force during arrests: A randomised controlled trial in a large British police force
"This study aims to assess the effect of body-worn cameras (BWCs) on police use of force, in a British police force context. We tested the effect of BWCs with a large British force in a six-month randomised controlled trial. Police shifts (n = 430) were randomly assigned on a weekly basis into treatment and control conditions. Odds ratios of use-of-force rates per arrests were used to estimate the causal impact of BWCs. Analyses of these odds for overall use of force and again within pre-specified force categories were conducted. Overall, we found a 50 percent reduction in the odds of force used when BWCs are present compared with control conditions. Our estimates suggest a 35 percent reduction of overall weighted force in the treatment conditions compared with control conditions. However, the effect concentrates in open-hand tactics (physical restraints and non-compliant handcuffing), with no discernible effect on categories of more aggressive force responses (for example, dogs, Tasers, batons, pepper spray); 40 percent 'more force' was detected in treatment conditions for handcuffing non-combatant suspects. We conclude that BWCs deter officers, offenders or both into complaint behaviour. Importantly, showing a conditional effect on force types can be further contextualised as enhanced transparency and accountability by the police, with greater reporting of use of force that would otherwise be concealed. Our findings illustrate the importance of analysing police use of force with and without compliant handcuffing of arrestees, which may or may not form part of the force continuum."

Armed with Technology: The Effects on Fatal Shootings of Civilians by the Police
"Deaths of civilians by the police in recent years have led to protests and disruptions inseveral cities, such as New York and Chicago. In this study, we investigate how the use of technology by the police affects deadly shootings of civilians. Drawing upon the criminology literature, we propose a simple, stylized model on a police officer’s decision-making to shoot to explain how technology use for intelligence analyses and evidence gathering affects the use of lethal force. Our empirical analyses revealed both encouraging and surprising findings. We found that both the use of smartphones and the statistical analyses of crime data are associated with a decrease in deadly shootings. In contrast, the use of wearable body cameras is related to an increase in fatal shootings by the police. We also found that the effect of technology use is more pronounced for armed suspects and among males, the youth, and minorities."

Police Body Cameras in Large Police Departments
"Body Worn Cameras are spreading worldwide, under the assumptionthat police performance, conduct, accountability, and legitimacy, in theeyes of the public, are enhanced as a result of using these devices. Inaddition, suspects’ demeanor during police–public engagements ishypothesized to change as a result of the video-recording of the encounter.For both parties—officers and suspects—the theoretical mechanism thatunderpins these behavioral changes is deterrence theory, self-awarenesstheory, or both. Yet evidence on the efficacy of Body Worn Camerasremains largely anecdotal, with only one rigorous study, from a small forcein Rialto, California, validating the hypotheses. How Body Worn Camerasaffect police–public interactions in large police departments remainsunknown, as does their effect on other outcomes, such as arrests. With oneDenver police district serving as the treatment area and five other districtswithin a large metropolitan area serving as comparisons, we offer mixedfindings as in the Rialto Experiment, not least in terms of effect magnitudes. Adjusted odds-ratios suggest a significant 35% lower odds forcitizens’ complaints against the police use of force, but 14% greater oddsfor a complaint against misconduct, when Body Worn Cameras are used.No discernable effect was detected on the odds of use of force at theaggregate, compared to control conditions (OR=0.928; p>0.1). Finally,arrest rates dropped significantly, with the odds of an arrest when BodyWorn Cameras not present is 18% higher than the odds under treatmentconditions. The outcomes are contextualized within the framework ofreactive emergency calls for service rather than proactive policing. Wefurther discuss officers’ decisions and the degree of the necessity of arrestin policing more broadly, because the burden of proof for tangible evidencenecessary for making a legal arrest can be challenged with the evidenceproduced by Body Worn Cameras: officers become “cautious” about arresting suspects when Body Worn Cameras are present. Limitationsassociated with the lack of randomly assigned comparison units arediscussed, as well, with practical recommendations for future research onBody Worn Cameras."

Mixed Results
Wearing body cameras increases assaults against officers and does not reduce police use of force: Results from a global multi-site experiment
"Police use of force is at the forefront of public awareness in many countries. Body-worn videos (BWVs) have been proposed as a new way of reducing police use of force, as well as assaults against officers. To date, only a handful of peer-reviewed randomised trials have looked at the effectiveness of BWVs, primarily focusing on use of force and complaints. We sought to replicate these studies, adding assaults against police officers as an additional outcome. Using a prospective meta-analysis of multi-site, multi-national randomised controlled trials from 10 discrete tests with a total population of +2 million, and 2.2 million police officer-hours, we assess the effect of BWVs on the rates of (i) police use of force and (ii) assaults against officers. Averaged over 10 trials, BWVs had no effect on police use of force (d = 0.021; SE = 0.056; 95% CI: –0.089–0.130), but led to an increased rate of assaults against officers wearing cameras (d = 0.176; SE = 0.058; 95% CI: 0.061–0.290). As there is evidence that cameras may increase the risk of assaults against officers, more attention should be paid to how these devices are implemented. Likewise, since other public-facing organisations are considering equipping their staff with BWVs (e.g. firefighters, private security, traffic wardens), the findings on risks associated with BWVs are transferrable to those occupations as well."

Existing and Ongoing Body Worn Camera Research: Knowledge Gaps and Opportunities
"The GMU team reviewed two areas of research to examine the state of, and researchquestions explored in, existing and ongoing empirical studies related to BWCs. Most researchhas been and is being conducted in law enforcement agencies (Section A). However, given thelikely impact of BWCs on court processes, we also examined the literature and existing projectsrelated to BWCs in that arena as well (Section B). Despite the rapid diffusion of BWCs, wediscovered significant gaps in our knowledge about their uses, as well as their intended andunintended consequences in both policing and court processes. Significant opportunities forfuture research projects are highlighted for each."

Evaluating the impact of police officer body-worn cameras (BWCs) on response-to-resistance and serious external complaints: Evidence from the Orlando police department (OPD) experience utilizing a randomized controlled experiment
"Purpose: To evaluate the effect of police body-worn cameras (BWCs) on officers' response-to-resistance (R2R) incidents and serious external complaints.Methods: A randomized experiment was used where 46 officers were randomly assigned to wear BWCs and 43 officers were randomly assigned to not wear BWCs. Pre- and post-BWC implementation outcome data was compared both between and within groups.Results: The results suggest that BWCs are an effective tool to reduce R2R incidents and serious external complaints. Specifically, the prevalence of R2R incidents and the prevalence and frequency of serious external complaints were significantly less for officers randomly assigned to wear BWCs. Pre-post comparisons within groups demonstrated that the reduction in the prevalence of R2R incidents (53.4% reduction) and external complaints (65.4% reduction) were statistically significant for the officers who wore the BWCs, and significant reductions in the frequency of these outcomes were detected as well. Overwhelming agreement was also found among officers who wore the BWCs for the utility of BWCs to improve evidence collection and report writing and improve their behavior and police work in general by having the opportunity to review their own BWC videos.Conclusions: Police departments would be prudent to consider adopting these devices in their agencies."

The Effect of Police Body-Worn Cameras on Use of Force and Citizens’ Complaints Against the Police: A Randomized Controlled Trial
"Police use-of-force continues to be a major source of international concern, inviting interest from academics and practitioners alike. Whether justified or unnecessary/excessive, the exercise of power by the police can potentially tarnish their relationship with the community. Police misconduct can translate into complaints against the police, which carry large economic and social costs. The question we try to answer is: do body-worn-cameras reduce the prevalence of use-of-force and/or citizens’ complaints against the police?MethodsWe empirically tested the use of body-worn-cameras by measuring the effect of videotaping police–public encounters on incidents of police use-of-force and complaints, in randomized-controlled settings. Over 12 months, we randomly-assigned officers to “experimental-shifts” during which they were equipped with body-worn HD cameras that recorded all contacts with the public and to “control-shifts” without the cameras (n = 988). We nominally defined use-of-force, both unnecessary/excessive and reasonable, as a non-desirable response in police–public encounters. We estimate the causal effect of the use of body-worn-videos on the two outcome variables using both between-group differences using a Poisson regression model as well as before-after estimates using interrupted time-series analyses.ResultsWe found that the likelihood of force being used in control conditions were roughly twice those in experimental conditions. Similarly, a pre/post analysis of use-of-force and complaints data also support this result: the number of complaints filed against officers dropped from 0.7 complaints per 1,000 contacts to 0.07 per 1,000 contacts. We discuss the findings in terms of theory, research methods, policy and future avenues of research on body-worn-videos."

Evaluating the Impact of Officer Worn Body Cameras in the Phoenix Police Department
"The Bureau of Justice Assistance (BJA), through the SMART Policing Initiative (SPI), awardedthe Phoenix Police Department $500,000 to purchase, deploy and evaluate police body worncameras. The design and implementation of the project included the purchase of 56 Body WornCamera (BWC) systems and deploying them in the Maryvale Precinct. The implementation ofthe BWC’s occurred in one of the two Maryvale Precinct squad areas (aka target area). Allofficers assigned to the target area were issued the equipment and were provided training in itsuse, maintenance, and related departmental policy. This evaluation was conducted to examinethe effect of implementing police worn body cameras on complaints against the police anddomestic violence case processing and outcomes.Our analysis of the camera meta-data indicated that only 13.2 to 42.2 percent of incidents wererecorded by and BWV camera. Domestic violence incidents were the most likely to be recorded(47.5%), followed by violent offenses (38.7), back-up (37%), status offenses (32.9%), andsubject/vehicle stops (30.9%). Other offense types were recorded less often. While in generalthe technology was found to be comfortable and easy to use, officers were dissatisfied with longdown load times, increased amount of time that it took to complete reports, and the possibilitythat video recordings might be used against them by the department. We also found that videosubmitted to the court was difficult to process because of logistical problems associated withchain of custody and the length of time that it took the prosecutors to review video files. Whilemany of the problems were addressed by the precinct commander by assigning a police officer toserve as a court liaison officer, prosecutors still maintained that they did not have enough time toreview video footage.Regardless, the officer worn body cameras were found to be beneficial to the officers and thecourt in a number of ways. First, officer productivity as measured through the number of arrestsincreased significantly. For instance, the number of arrests increased by about 17% among thetarget group compared to 9% in the comparison group. Second, complaints against the policedeclined significantly. Complaints against officers who wore the cameras declined by 23%,compared to a 10.6% increase among comparison officers and 45.1% increase among patrolofficers in other precincts. Third, our data showed that those officers who wore cameras andreceived a complaint were significantly less likely to have the complaint sustained whencompared to the comparison group and other patrol officers throughout the PPD. This suggeststhat even if a complaint was made against a camera wearing officer the video file was likely toprovide support to the officer. Fourth, and related, the officer self-report data suggested that asignificant number of complaints were not pursued because of video recordings. BWC did notappear, however, to have an impact on s"

Self-Awareness to Being Watched and Socially-Desirable Behavior: A Field Experiment on the Effect of Body-Worn Cameras on Police Use-of-Force
"This study was conducted to determine whether body cameras worn by police officers would reduce the incidences of police-use-of-force. Findings from the study include the following: shifts in which officers did not use body cameras experienced twice as many incidents of police-use-of-force compared to shifts where officers used body cameras; and the number of complaints against the police for excessive use of force dropped from 28 complaints in the 12 months prior to the study to 3 during the study period. Researchers were unable to compute a treatment effect due to the large overall reduction in the number of complaints. The study was conducted with the assistance of the Rialto Police Department. All 54 frontline officers in the department participated in the study. The officers were randomly assigned to either the control group – no use of body cameras, or the experimental group – use of body cameras. The officers in the experimental group were instructed to wear the body cameras during their entire shift and to record all public-police encounters. The content of the videotapes were analyzed to determine the effect of the camera on the incidences of police-use-of-force. The findings from the analysis suggest that the presence of the cameras resulted in an almost 50 percent reduction in the total number of incidents of use of force, and that when cameras were not used (the control group), citizen complaints were almost 10 times higher compared to the experimental group. Suggestions for future research are discussed. Tables, figure, and references"

Leading an Experiment in Police Body-Worn Video Cameras
"Body-worn video (BWV) is seen internationally as having the potential to reduce public complaints against police, police use of force, and attrition of prosecutions due to lack of physical evidence. Beyond the Cambridge trial in Rialto, California, however, no studies have tested the effects of BWV. The present study documents a Police leaders’ implementation of a randomized controlled trial of the use of BWV.

The main objectives are to identify the challenges to implementing a trial and identify how they were overcome. The solutions to these challenges may provide key lessons for police leaders, not only as they undertake evidence-based testing, but also as they manage police operations and implement change.

EFFECTS OF AN OBSERVER ON HAND WASHING IN A PUBLIC RESTROOM
"Summary.-This experiment tests a prediction derived from social influence theories that increased awareness of self enhances normative behavior, specifically, that the frequency and duration of handwashing in a public restroom will be increased by the presence of an observer. When a second person was present, 24 of 31 female subjects washed their hands after using toilet facilities, while only 11 of 28 washed when they were alone. Among those who washed, no significant difference in duration of washing was observed.

The results are consistent with Wicklund's theory of obiective self-awareness and other theories of social influence."

Increasing Cooperation With the Police Using Body Worn Cameras
"What can change the willingness of people to report crimes? A 6-month study in Denver investigated whether Body Worn Cameras (BWCs) can change crime- reporting behavior, with treatment-officers wearing BWCs patrolling targeted street segments, while control officers patrolled the no-treatment areas without BWCs. Stratified street segments crime densities were used as the units of analysis, in order to measure the effect on the number of emergency calls in target versus control street segments.

Repeated measures ANOVAs and subgroup analyses suggest that BWCs lead to greater willingness to report crimes to the police in low crime density level residential street segments, but no discernable differences emerge in hotspot street segments. Variations in reporting are interpreted in terms of accountability, legitimacy, or perceived utility caused by the use of BWCs. Situational characteristics of the street segments explain why low-level street seg- ments are affected by BWCs, while in hotspots no effect was detected"

Objective Self-Awareness
"This chapter focuses on the theory of objective self-awareness. It presents the theory of objective self-awareness as it stands presently: Conscious attention is viewed as dichotomous, having the property of being directed either toward the self or toward the environment. The direction of attention is guided by events that force attention inward, such as reflections of the self, and events that pull attention outward, such as distracting stimuli outside the self.

Under objective self-awareness, the person will experience either negative or positive affect depending on whether attention is directed toward a negative or a positive discrepancy. The chapter illustrates the operation of a principle that is new to the theory. There are three studies relevant to this new proposition—two on self-esteem and one on attribution.

Escaping objective self-awareness has been highlighted. The evolved theory of objective self-awareness has ramifications for three conceptual phenomena: (1) The initial reaction to self-focused attention is self-evaluation, which can be either favorable or unfavorable, depending on the nature of the salient within-self discrepancy; (2) The onset of self-focused attention generates attempts to avoid mirrors and similar stimuli, given that salient discrepancies are negative, and in experimentation, attention can be taken from the self through passive diversions as well as through motor activities; (3) If there is no escape from self-focusing stimuli, discrepancy reduction will then follow. © 1975, Academic Press Inc."

Officer Perceptions of Body-Worn Cameras Before and After Deployment
"Over the past few years, several events have highlighted the strained relationship between the police and residents in many communities. Police officer body-worn cameras (BWCs) have been advocated as a tool by which police–community relations can be strengthened, while simultaneously increasing transparency and accountability of police departments. Support for BWCs from the public and federal government is strong, and some studies have examined police perceptions of BWCs. However, comparisons of officer perceptions of BWCs in different departments are lacking, as are assessments of officer attitudes pre- and post-BWC deployment. This study compares officer perceptions of BWCs in three police departments in the western United States between 2013 and 2015, both before and after BWC program implementation. The similarities and differences among officer perceptions across departments are examined, and the authors consider the implications of findings for police departments moving forward with BWC technology."

Cops and cameras: Officer perceptions of the use of body-worn cameras in law enforcement
"Purpose
There has been a recent surge in the adoption of and media attention to the use of body-worn cameras in law enforcement. Despite this increase in use and media attention, there is little to no research on officer perceptions of body-worn cameras.

Methods
This study relies on baseline data of officer perceptions toward body-worn cameras collected from surveys administered to Orlando Police officers who are participants in a randomized experiment evaluating the impact of body-worn cameras (Taser AXON Flex) in law enforcement.

Results
Results suggest that police officers are, by and large, open to and supportive of the use of body-worn cameras in policing, they would feel comfortable wearing them, and that they perceive a potential for benefits of body-worn cameras in improving citizen behavior, their own behavior, and the behavior of their fellow officers.

Conclusions
Officers are generally supportive of body-worn cameras, and they hold perceptions that these devices can be beneficial in positively affecting relevant outcomes. Study limitations and implications are also discussed."
