Police Officers on Drug Corners in Philadelphia,Drug Crime,and Violent Crime: Intended,Diffusion, and Displacement Impacts

On May 1, 2002, the Philadelphia Police Department launched Operation Safe Streets, stationing officers at 214 of the highest drug activity locations in the city 24 hours a day, 7 days a week. Interrupted time series (AutoRegressive Integrated Moving Average) models on weekly data isolated citywide and local program impacts on all violent crimes, murder, and reported drug crimes. Results showed no significant impacts on citywide weekly counts for drug crimes, homicides, or all violent crimes. Geographically focused analyses showed significant localized intervention impacts for both violent and drug crimes. Analyses of high‐drug‐activity non‐intervention sites suggest: the program impacts seen were not an artifact of history or local history; significant spatial diffusion of preventive benefits for violent crime; and probably significant spatial displacement for drug crime. Stationary targeted drug‐enforcement interventions like Operation Safe Streets may differentially affect the locational selection processes behind violent crime versus drug crime.     

From the Officer’s Perspective: A Multilevel Examination of Citizens’ Demeanor during Traffic Stops

Over the past 60 years, a substantial body of research has considered the influence of citizens’ demeanor on police behavior; and more recently, the correlates of citizens’ demeanor. This study advances our understanding of the demeanor construct by measuring officers’ perceptions of citizens’ disrespect, non‐compliance, and resistance during traffic stops. Using multilevel statistical models, we examine the correlates of citizens’ demeanor and assess the racial differences in these perceptions. The findings demonstrate that officers’ perceptions of citizens’ demeanor vary across racial/ethnic groups, after controlling for other relevant factors. Although White officers were significantly more likely than Black officers to classify drivers as disrespectful, Black and White officers were equally likely to report drivers as displaying behaviors that were non‐compliant and/or verbally resistant. Black drivers were significantly more likely to be reported as disrespectful, non‐compliant, and/or resistant, regardless of the officers’ race. The implications for future research and policy are discussed.     

A Stone’s Throw from the Metropolis: Re-Examining Small-Agency Homeland Security Practices

Police agencies nationwide have enhanced their homeland security preparedness capacity since the 9/11 attacks. Evidence suggests that departments have not uniformly adopted measures to prepare for and respond to critical incidents. Rather, larger agencies are more likely than their smaller peers to take such steps. Small agencies do not constitute a homogenous group; some experience geographic isolation while others are near major metropolitan areas. Unclear is whether small agencies (25 or fewer full-time sworn personnel), those that are commonly found to be less prepared, benefit from proximity to large-agency peers. This study examined whether physical and relational proximity to large departments contributed to homeland security preparedness in over 300 small departments. A structural equation model revealed that interactions with large agencies facilitated preparedness but physical proximity had no direct effect. Increasing geographic isolation from large-agency peers indirectly affected preparedness by stifling the level of inter-department interactions.     

Measuring Procedural Justice in Police-Citizen Encounters

Procedural justice has dominated recent discussions of police interactions with the public. It has mostly been measured from the perspective of citizens (using surveys or interviews), but several important questions about predictors and outcomes of fair police treatment are best answered using direct observations of police-citizen interactions. Building on prior observational studies, we develop and validate an instrument for measuring procedural justice as it is exercised by the police in the natural setting of their encounters with the public. In doing so, we adopt a “formative” rather than the common “reflective” approach, based on the assumption that specific behaviors that make up procedural justice do not reflect a single underlying construct but rather form one. We justify this approach and validate our instrument accordingly. We also discuss the implications of our measurement for future research on procedural justice in police behavior.     

Researching counterterrorism: a critical perspective from the field in the light of allegations and findings of covert activities by undercover police officers

The article addresses some of the key issues that are raised for researchers engaging with counterterrorism police officers and initiatives, when undertaking research. A significant area to explore in this context is, in fact, the issue of relationships with counterterrorism police officers who may themselves directly have been covert police officers in the past and/or who may be continuing in their current, apparently more open, role (wittingly or otherwise) as agents of broader state strategies of exploiting trust for intelligence-gathering purposes. This article suggests that it is important for researchers to understand that working within the counterterrorism field involves degrees and shades of risk in the service of trust-building, sensitivity and the empowerment of communities, and that researchers themselves can (wittingly and unwittingly) be part of wider strategies instigated by security-minded individuals or groups of counterterrorism police officers. Reflecting upon the research that we have undertaken individually and collectively over the last number of years, in the light of the most recent spate of allegations about counterterrorism police officers infiltrating activist and political protest groups, having sexual relationships, and indeed, on occasion, children, with women whilst undercover and of potentially working to entrap vulnerable individuals into planning terrorist acts, this article raises questions around trust, credibility, legitimacy, the prevalence and near unavoidability of dysfunctional agendas and the implications of all of the above for community-based approaches to counterterrorism.     

Public assistance of police during criminal investigations: Russian experience

This study examines the high levels of public unwillingness to assist police in criminal investigations in Russia. Variables of public trust of police, fear of crime, victimization, and prior contact with police are used to explain this phenomenon. Also included in the study are variables of police fear and avoidance of police. The findings suggest that higher levels of distrust in, as well as fear and avoidance of police are strong predictors of citizens’ unwillingness to assist police in Russia. The paper discusses potential implications of these findings for the 2011 police reform in Russia.     

论警务实战指挥决策风险与控制

指挥决策风险在警务实战行动中是客观存在的。风险与决策风险是由若干要素构成的。在实战中,决策风险直接影响和制约指挥活动的成效,决定实战行动的成败。通过分析,我们可以了解和掌握影响决策风险的要素。对指挥决策风险进行有效控制,这是公安机关指挥员的一个重要任务和课题。     

论社区警务与犯罪控制

社区警务是当前及今后相当长历史时期内我国警务建设及警学研究的重点。实施社区警务是增进警民联系、构建和谐社会的重要战略决策,实施社区警务的终极目的就是控制犯罪。正确处理好社区警务与犯罪控制之间的关系,是促进社区警务在维护社会稳定与和谐中发挥作用的重要保障。
