Abstract The stay-at-home restrictions to control the spread of COVID-19 led unparalleled sudden change in daily life, but it is unclear how they affected urban crime globally. We collected data on counts 27 cities across 23 countries Americas, Europe, Middle East and Asia. conducted interrupted time series analyses assess impact different types each city. Our findings show that policies were associated with a considerable drop crime, substantial variation crime. Meta-regression results...
Police use of force is at the forefront public awareness in many countries. Body-worn videos (BWVs) have been proposed as a new way reducing police force, well assaults against officers. To date, only handful peer-reviewed randomised trials looked effectiveness BWVs, primarily focusing on and complaints. We sought to replicate these studies, adding officers an additional outcome. Using prospective meta-analysis multi-site, multi-national controlled from 10 discrete tests with total...
This paper synthesizes the effects on repeat offending reported in ten eligible randomized trials of face-to-face restorative justice conferences (RJCs) between crime victims, their accused or convicted offenders, and respective kin communities. After an exhaustive search strategy that examined 519 studies could have been for our rigorous inclusion criteria, we found did. Included measured recidivism by 2 years convictions after random assignment 1,880 offenders who had consented to meet...
Previous studies on tax compliance have focused primarily the tax‐reporting behavior of individuals. This study reports results from a randomized field test effects deterrence and moral persuasion 4,395 corporations in Israel. Two experimental groups received letters, one conveying deterrent message other message. Three types measures are used to evaluate based magnitude difference‐in‐differences means 1) gross sales values reported authority, 2) dollars paid 3) deductions. Overall, both...
Our multisite randomized controlled trial reported that police body-worn cameras (BWCs) had, on average, no effect recorded incidents of use force. In some sites, rates force decreased and in others increased. We wanted to understand these counter-intuitive findings report pre-specified subgroup analyses related officers' discretion activating the BWCs. Using pre-established criteria for experimental protocol breakdown terms treatment integrity, ten sites were subgrouped into...
The use of body-worn cameras (BWCs) by the police is rising. One proposed effect BWCs reducing complaints against police, which assumes that reduce officer noncompliance with procedures, improve suspects’ demeanor, or both, leading to fewer complaints. We report results from a global, multisite randomized controlled trial on whether BWC reduces citizens’ Seven discrete tests ( N = 1,847 officers), shifts as unit analysis 4,264), were randomly assigned into treatment and control conditions....
To determine whether crime-reduction effects of increased police patrols in hot spots are dependent on the "hard" threat immediate physical arrest, or "soft" by civilian (but uniformed) staff with few arrest powers and no weapons can also reduce crime. We sought to assess number discrete patrol visits a spot was more less important than total minutes presence across all visits, based counts crime would be consistent Crime Harm Index outcome. randomly assigned 72 into 34 treatment units 38...
Practitioners dealing with domestic abuse often claim that the problem escalates over time in both seriousness and frequency. We tested those claims on 36,000 police records of between 2009 2014 reported to Suffolk Constabulary east England. Using Cambridge Crime Harm Index as measure harm severity, we found no escalation majority cases; 76% all unique victim offender units (dyads) had zero repeat calls. Among cohort 727 dyads who called 5 or more times, there was evidence for statistically...
Purpose The purpose of this paper is to review the extant published literature on body-worn cameras (BWCs) in policing, specifically context how BWCs affect both citizens and officers. Design/methodology/approach current study a narrative impact police generated through search four repositories (Google Scholar, Criminal Justice Abstracts, EBSCO Host, PsychInfo). Findings identified 21 articles that matched selection criteria. In general, body research demonstrates that: are supportive BWC...
What can change the willingness of people to report crimes? A 6-month study in Denver investigated whether Body Worn Cameras (BWCs) crime-reporting behavior, with treatment-officers wearing BWCs patrolling targeted street segments, while control officers patrolled no-treatment areas without BWCs. Stratified segments crime densities were used as units analysis, order measure effect on number emergency calls target versus segments. Repeated measures ANOVAs and subgroup analyses suggest that...
Police body-worn cameras (BWCs) are an increasingly prominent research area in criminal justice. This trend mirrors current practice, with more and law enforcement agencies implementing or procuring BWCs. Yet the evidence on BWCs is substantially long but rather short theory. Why should 'work' under what conditions whom? article offers a robust theoretical composition for causal mechanisms that can explain efficacy of What sets them apart from other surveillance devices, such as...
Recently, scholars have applied self-awareness theory to explain why body-worn cameras (BWCs) affect encounters between the public and police, with its most immediate manifestation being a reduction in use of force by complaints against police. In this study, we report on paradoxical effects BWCs context assaults officers. A multisite randomized controlled trial ten departments, officers wearing (or not wearing) based random assignment shifts. Odds ratios are used estimate treatment effect...
Police legitimacy is generally regarded as a view among community members that police departments play an appropriate role in implementing rules governing public conduct. Placing body worn cameras (BWCs) on officers has been suggested potentially important response to crises. We use rigorous controlled quasi-experimental evaluation test the impact of BWCs citizen perceptions procedural justice and during traffic stops Turkey. Relative by without BWCs, we find motorists stopped with reported...
In late 2013, Trinidad and Tobago Police Service (TTPS) conducted the first randomized experiment ever to test a hot spots patrol strategy (HSPS) across large areas, as distinct from testing extra patrols one spot at time. The HSPS required, helped refine, formal theory of both causes effects directed in spots. This article presents an integrated how implement ways that maximize preventive on crime. It then describes experimental protocol used Trinidad. key elements are scaling up specific...
A fairly robust body of evidence suggests that hotspots policing is an effective crime prevention strategy. In this paper, we present contradictory a backfiring effect. randomized controlled trial, aimed at reducing and disorder, London's 'hottest' 102 bus-stops were targeted. Double patrol teams Metropolitan Police Service uniformed officers visited the stops three times per shift (12:00–20:00), 5-times week, for duration 15 min, over 6 month period. Crucially, arrived departed bus stop on...
This study aims to assess the effect of body-worn cameras (BWCs) on police use force, in a British force context. We tested BWCs with large six-month randomised controlled trial. Police shifts ( n = 430) were randomly assigned weekly basis into treatment and control conditions. Odds ratios use-of-force rates per arrests used estimate causal impact BWCs. Analyses these odds for overall again within pre-specified categories conducted. Overall, we found 50 percent reduction when are present...
Body-worn video (BWV) is seen internationally as having the potential to reduce public complaints against police, police use of force, and attrition prosecutions due lack physical evidence. Beyond Cambridge trial in Rialto, California, however, no studies have tested effects BWV. The present study documents a Police leaders’ implementation randomized controlled main objectives are identify challenges implementing how they were overcome. solutions these may provide key lessons for leaders,...
Body Worn Cameras are spreading worldwide, under the assumption that police performance, conduct, accountability, and legitimacy, in eyes of public, enhanced as a result using these devices. In addition, suspects’ demeanor during police–public engagements is hypothesized to change video-recording encounter. For both parties—officers suspects—the theoretical mechanism underpins behavioral changes deterrence theory, self-awareness or both. Yet evidence on efficacy remains largely anecdotal,...
