Purpose Virus epidemics may be mitigated if people comply with directives to stay at home and keep their distance from strangers in public. As such, there is a public health interest in social distancing compliance. The available evidence on distancing practices in public space is limited, however, by the lack of observational data. Here, we apply video observation as a method to examine to what extent members of the public comply with social distancing directives. Data Closed Circuit Television (CCTV) footage of interactions in public was collected in inner-city Amsterdam, the Netherlands. From the footage, we observed instances of people violating the 1.5-meter distance directives in the weeks before, during, and after these directives were introduced to mitigate the COVID-19 pandemic. Results We find that people complied with the 1.5-meter distance directives when these directives were first introduced, but that the level of compliance started to decline soon after. We also find that violation of the 1.5-meter distance directives is strongly associated with the number of people observed on the street and with non-compliance to stay-at-home directives, operationalized with large-scale aggregated location data from cell phones. All three measures correlate to a varying extent with temporal patterns in the transmission of the COVID-19 virus, temperature, COVID-19 related Google search queries, and media attention to the topic. Conclusion Compliance with 1.5 meter distance directives is short-lived and coincides with the number of people on the street and with compliance to stay-at-home directives. Potential implications of these findings are that keep- distance directives may work best in combination with stay-at-home directives and place-specific crowd-control strategies, and that the number of people on the street and community-wide mobility as captured with cell phone data offer easily measurable proxies for the extent to which people keep sufficient physical distance from others at specific times and locations.

Half a century of research on bystander behavior concludes that individuals are less likely to intervene during an emergency when in the presence of others than when alone. By contrast, little is known regarding the aggregated likelihood that at least someone present at an emergency will do something to help. The importance of establishing this aggregated intervention baseline is not only of scholarly interest but is also the most pressing question for actual public victims-will I receive help if needed? The current article describes the largest systematic study of real-life bystander intervention in actual public conflicts captured by surveillance cameras. Using a unique cross-national video dataset from the United Kingdom, the Netherlands, and South Africa (N = 219), we show that in 9 of 10 public conflicts, at least 1 bystander, but typically several, will do something to help. We record similar likelihoods of intervention across the 3 national contexts, which differ greatly in levels of perceived public safety. Finally, we find that increased bystander presence is related to a greater likelihood that someone will intervene. Taken together these findings allay the widespread fear that bystanders rarely intervene to help. We argue that it is time for psychology to change the narrative away from an absence of help and toward a new understanding of what makes intervention successful or unsuccessful.

Night-time economy (NTE) leisure zones, while providing local economic growth and positive social experiences, are hotspots for urban public violence. Research aimed at better understanding and thus reducing this violence has employed a range of empirical methods: official records, self-reports, experiments, and observational techniques. In this paper, we review the applications of these methodologies for analyzing NTE violence on key research dimensions, including mapping incidents across time and space; interpreting the motivations and meaning of violence; identifying social psychological background variables and health consequences; and the ability to examine mid-violent interactions. Further, we assess each method in terms of reliability, validity, and the potential for establishing causal claims. We demonstrate that there are fewer and less established methodologies available for examining the interactional dynamics of NTE violence. Using real-life NTE bystander intervention as a case example, we argue that video-based behavioral analysis is a promising method to address this gap. Given the infancy and relative lack of exposure of the video observational method, we provide recommendations for scholars interested in adopting this technique.

Objectives:The widespread use of camera surveillance in public places offers criminologists the opportunity to systematically and unobtrusively observe crime, their main subject matter. The purpose of this essay is to inform the reader of current developments in research on crimes caught on camera.Methods:We address the importance of direct observation of behavior and review criminological studies that used observational methods, with and without cameras, including the ones published in this issue. We also discuss the uses of camera recordings in other social sciences and in biology.Results:We formulate six key insights that emerge from the literature and make recommendations for future research.Conclusions:Camera recordings of real-life crime are likely to become part of the criminological tool kit that will help us better understand the situational and interactional elements of crime. Like any source, it has limitations that are best addressed by triangulation with other sources.

Objectives: Drawing on the rational choice perspective, this study aims at explaining why some robberies take place with physical force while others occur only with threat. The focus is how expected and observed victim resistance impact physical force by robbers. Methods: We draw on quantitative and qualitative data obtained from 104 robbers who described 143 robbery events. Based on the coding of behavioral sequences between offenders and victims, we distinguish between the use of physical force at the onset from the use of physical force during the progression of the event. Results: At the onset of robberies, physical force of offenders is influenced by whether they judge the victim to be street credible. During the progression of robberies, offenders are more likely to use physical force against a resistant than against a compliant victim. Conclusions: At the onset of the robbery, offender violence is related to expected victim resistance; during the progression, it is related to observed victim resistance. Future research should focus on behavioral sequences within robbery events including the meaning of victim characteristics and victim behavior in different phases of the event.

Post-aggression consolation is assumed to occur in humans as well as in chimpanzees. While consolation following peer aggression has been observed in children, systematic evidence of consolation in human adults is rare. We used surveillance camera footage of the immediate aftermath of nonfatal robberies to observe the behaviors and characteristics of victims and bystanders. Consistent with empathy explanations, we found that consolation was linked to social closeness rather than physical closeness. While females were more likely to console than males, males and females were equally likely to be consoled. Furthermore, we show that high levels of threat during the robbery increased the likelihood of receiving consolation afterwards. These patterns resemble post-aggression consolation in chimpanzees and suggest that emotions of empathic concern are involved in consolation across humans and chimpanzees.

The coupling of racial and economic stratification has been found to result in a range of adverse outcomes for youth of color, including disproportionate exposure to violence and victimization. Primary explanations of these patterns, particularly at the micro-level, have focused on the impact of street culture. In this article, we draw from a multiyear ethnography in Cape Town, South Africa, to offer a theoretical elaboration of the place of culture in contributing to victimization risks among urban minority young men. The study is based on data collected from a sample of 26 young men of color who lived on the Cape Flats between 2003 and 2006. Using grounded theory methods, we suggest the *
