Good cop—Bad cop: Problem officers,law enforcement culture,and strategies for success

Police officers are the only professionals mandated by society to use discretionary coercive physical force as a necessary component of fulfilling their duty to maintain public safety and uphold the law. If community policing is to prevail as an effective and credible style of law enforcement, the legitimate use of competent police authority will continue to be a vital issue. This article analyzes the types of officer problems and problem officers that can harm community policing efforts. These include (1) individual factors, such as attitudes, personality traits, and psychological disorders; (2) police-citizen interaction factors, such as interpersonal dynamics and community attitudes; and (3) organizational factors, such as training and supervision, departmental philosophy, and the “cop culture.” The article then offers practical strategies for improving officer performance, including (1) selection and screening of officers; (2) training and supervision; (3) fitnessfor-duty evaluations; (4) effective supervision and discipline; (5) coaching and counseling strategies; and (6) the most productive use of psychological services. Throughout this discussion, the concept of the police officer as a law enforcement professional is emphasized as essential for guiding public safety policy into the 21^st century.     

Asphyxia Homicides in Finland, 1983–2012

Finland has one of the highest homicide rates in Western Europe, and almost every tenth homicide is caused by asphyxiation. Reliable statistics, a strict legislation, and an exceptionally high medico-legal autopsy rate formed a base for a nationwide analysis of asphyxia homicides (n = 383) during 30 years. The cases were identified through multiple records, and all the forensic pathology case files were studied in detail. In more than one out of five cases, there were indications of staging, and the homicide was revealed first at autopsy in close to one in ten cases. The vast majority of the homicides took place in private locations and involved persons known to each other. Every third victim was an intimate partner, and every tenth a child. Almost half of the victims died from manual strangulation, one in three from ligature strangulation. Smothering, choking, neck compression with a firm object, and thoracic compression were more rare methods. Drownings were excluded from this study material. Of all the victims, 7% had no observable external injuries. Petechiae were recorded in approximately in 61%, laryngohyoid fractures in 47%, and vocal cord hemorrhages in 16% of the cases. Every tenth female victim had genital injuries. Toxicological analyses were performed in close to all of the cases, and almost three out of four victims tested positive for blood alcohol. The various aspects of the demographics and autopsy findings covered in this study contribute reliable and accurate data to further strengthen the spectrum of observable medico-legal characteristics of asphyxia homicides.     

China’s private international law (1978–2008)

Since 1978, China’s private international law has made great achievements in publication of textbooks and reference materials, translation of foreign works, academic research, construction of subjects and disciplines as well as participation in international exchanges. The research on academic issues, to some extent, has helped to address various puzzles in legislation, judicature and construction of the discipline of China’s private international law, and has formed some theories in the representation of “one body of two wings.” Although there are still some flaws and issues, Chinese scholars in this field have both the capability and the mission to create a theoretical system for private international law with Chinese characteristics.     

Racial composition,sentencing reforms,and rates of incarceration, 1970–1980

Association with delinquent peer groups is one of the most salient predictors of delinquent behavior. Despite the widespread documentation of these effects, little is known about whether the delinquent peer effect is conditioned by individual‐level characteristics. Using data from a multi‐wave survey of Mexican‐American adolescents, this study explored the interactive effect of susceptibility to peer influence and differential association with delinquent peers on delinquent outcomes. Results suggested that the delinquent peer effect on self‐reported delinquency is amplified when an adolescent is highly susceptible to peer influence. Analyses also indicated that this moderating effect varies according to offense seriousness. Specifically, the conditioning effect is most important when considering acts of serious delinquency.

Federal–local partnerships on immigration law enforcement: Are the policies effective in reducing violent victimization?

Research Summary

Our understanding of how immigration enforcement impacts crime has been informed exclusively by data from police crime statistics. This study complements existing research by using longitudinal multilevel data from the National Crime Victimization Survey for 2005–2014 to simultaneously assess the impact of the three predominant immigration policies that have been implemented in local communities. The results indicate that the activation of Secure Communities and 287(g) task force agreements significantly increased violent victimization risk among Latinos, whereas they showed no evident impact on victimization risk among non-Latino Whites and Blacks. The activation of 287(g) jail enforcement agreements and anti-detainer policies had no significant impact on violent victimization risk during the period.

Policy Implications

Contrary to their stated purpose of enhancing public safety, our results show that the Secure Communities program and 287(g) task force agreements did not reduce crime, but instead eroded security in U.S. communities by increasing the likelihood that Latinos experienced violent victimization. These results support the Federal government's ending of 287(g) task force agreements and its more recent move to end the Secure Communities program. Additionally, the results of our study add to the evidence challenging claims that anti-detainer policies pose a threat to violence risk.     

Strengthening cross-border law enforcement cooperation in the EU: the Prüm network of data exchange

The Prüm network was established to provide mechanisms and the infrastructure to achieve a closer cooperation between the EU member states in combating terrorism, organised crime and illegal immigration through the cross border exchange of DNA profiles, fingerprints and vehicle registration data. While Prüm offers clear benefits for cross-border policing, it continues to present challenges of a technical and scientific nature as well as legal, ethical and socioeconomic concerns. This article reviews these challenges as well as the existing safeguards. It argues that, in order to achieve Prüm benefits and maximise its potential, it is important to enhance the necessary dialogue and cooperation between member states so as to confront the above concerns and address challenges posed by Prüm through balanced measures.     

Progressing with the reform and opening up: Retrospective of China’s civil law (1978–2008)

Over the past 30 years, Chinese civil and commercial law has made great achievements in providing theoretical support for Chinese legislation, establishing a theoretical system of civil and commercial law with Chinese characteristics, conducting in-depth and comparative research in this field, and making many summaries of trial practices, judicial interpretations and case studies of civil and commercial affairs. The academic circle has expressed professional comments regarding public events. The major theoretical breakthroughs include the clarification of the relationship between civil law and economic law, further research on the civil code system, basic consensus on the integration of civil law and commercial law, formation of the theoretical system of property right law with Chinese characteristics, innovation and development of contract law theories, basic information of personality law theories, and formation of the theoretical system of tort law. The orientation of Chinese civil and commercial law is to enhance comparative research on civil and commercial law nationally and internationally, focusing on the diversity of research methodologies.     

Do all the pieces matter? Assessing the reliability of law enforcement data sources for the network analysis of wire taps

Law enforcement agencies rely on data collected from wire taps to construct the organisational chart of criminal enterprises. Recently, a number of academics have also begun to utilise social network analysis to describe relations among criminals and understand the internal organisation of criminal groups. However, before drawing conclusions about the structure or the organisation of criminal groups, it is important to understand the limitations that selective samples such as wire taps may have on network analysis measures. Electronic surveillance data can be found in different kinds of court records and the selection of the data source is likely to influence the amount of missing information and, consequently, the results. This article discusses the impact that the selection of a specific data source for the social network analysis of criminal groups may have on centrality measures usually adopted in organised crime research to identify key players.     

The art of trolling law enforcement: a review and model for implementing ‘flame trolling' legislation enacted in Great Britain (1981–2012)

The advancement of information and communications technology often results in early adoption, followed by concern over a digital divide, followed by mass adoption and then, inevitably, abuse and misuse of that platform. The most recent of these technologies is social networking services. The early adopters used Friendster and MySpace, and the masses now use Facebook and Twitter. The abuse of people on these platforms was called Cyberbullying in the case of the first two in the 2000s, and Internet trolling in the case of the second two in the 2010s. This paper reviews the legislation enacted in the UK parliament between 1981 and 2012 to deal with these offences, called ‘flame trolling’, for those based on transgress humour, or electronic message faults more generally. The paper presents a framework that includes a ‘Trolling Magnitude Scale’ based on established trolling culture, in order to link the legislative offences to the severities of those faults, as well as to the ability of specific Internet users to tolerate them or otherwise. The paper concludes that by using this framework law enforcement agencies such as the police can apply the laws more fairly and proportionally to protect free speech and at the same time be tough on the causes of electronic message faults in the form of Internet abuse and data misuse.     

Immigration and the Changing Nature of Homicide in US Cities, 1980–2010

Objectives

Previous research has neglected to consider whether trends in immigration are related to changes in the nature of homicide. This is important because there is considerable variability in the temporal trends of homicide subtypes disaggregated by circumstance. In the current study, we address this issue by investigating whether within-city changes in immigration are related to temporal variations in rates of overall and circumstance-specific homicide for a sample of large US cities during the period between 1980 and 2010.

Methods

Fixed-effects negative binomial and two-stage least squares (2SLS) instrumental variable regression models are used to analyze data from 156 large US cities observed during the 1980–2010 period.

Results

Findings from the analyses suggest that temporal change in overall homicide and drug homicide rates are significantly related to changes in immigration. Specifically, increases in immigration are associated with declining rates for each of the preceding outcome measures. Moreover, for several of the homicide types, findings suggest that the effects of changes in immigration vary across places, with the largest negative associations appearing in cities that had relatively high initial (i.e., 1970) immigration levels.

Conclusions

There is support for the thesis that changes in immigration in recent decades are related to changes in rates of lethal violence. However, it appears that the relationship is contingent and varied, not general.

Public servants or police soldiers? An analysis of opinions on the militarization of policing from police executives,law enforcement,and members of the 114th congress U.S. house of representatives

Despite the dramatic rise in use of militarized weapons, equipment, and tactics by police departments across the nation, no study has examined the opinions of those responsible for designing, funding, and implementing police militarization in the United States. Therefore this study collected and analyzed opinion data from 465 key stakeholders from the 114th Congress U.S. House of Representatives, law enforcement executives, and local police officers regarding police militarization. Results suggest that while most practitioners and policymakers favor police militarization, Congress and law enforcement differ in support of critical issues such as oversight of military procurement programs, use of surplus military weapons and vehicles, and overall support for the militarization of policing in the United States.     

Changes in homeland security activities since 9/11: an examination of state and local law enforcement agencies’ practices

This study investigated differences in state and local law enforcement agencies participation in homeland security activities within the year after the 9/11 terrorist attacks and 13 years later. Further, this investigation assessed whether there were regional differences for these practices during these same time periods. Activities assessed were based on a homeland security initiatives index. Data suggest that, in the year after the attacks, agencies’ participation in all of Stewart and Morris’ homeland security activities was not high and statistically significant differences existed across several regions for some of these practices. However, since then, the number of agencies participating in all of Stewart and Morris’ homeland security activities increased and statistically significant differences between regions decreased. The increase in participation may be attributed to incentives provided by the federal government. Nevertheless, data suggest that support may be waning within law enforcement agencies to participate in homeland security activities.     

Democracy,rule of law and human rights protection under gradually developed constitutionalism —by the clue of administrative law

With the shifting of the economic pattern and the developing of administrative law, the modern constitutionalism of China has adopted a progressive development process. Over 20 years, the development of democracy, the rule of law and the human rights protection clearly illustrate this point. For the gradually developing constitutionalism, the theory of limited rational is a theoretical basis, the stability of society is a social basis, the changing economic system is a economic basis, and Confucianism is a cultural basis. Constitutionalism of China should continue to go in such an active, steady and gradual way.     

The Concentration and Stability of Gun Violence at Micro Places in Boston, 1980–2008

Boston, like many other major U.S. cities, experienced an epidemic of gun violence during the late 1980s and early 1990s that was followed by a sudden large downturn in gun violence in the mid 1990s. The gun violence drop continued until the early part of the new millennium. Recent advances in criminological research suggest that there is significant clustering of crime in micro places, or “hot spots,” that generate a disproportionate amount of criminal events in a city. In this paper, we use growth curve regression models to uncover distinctive developmental trends in gun assault incidents at street segments and intersections in Boston over a 29-year period. We find that Boston gun violence is intensely concentrated at a small number of street segments and intersections rather than spread evenly across the urban landscape between 1980 and 2008. Gun violence trends at these high-activity micro places follow two general trajectories: stable concentrations of gun assaults incidents over time and volatile concentrations of gun assault incidents over time. Micro places with volatile trajectories represent less than 3% of street segments and intersections, generate more than half of all gun violence incidents, and seem to be the primary drivers of overall gun violence trends in Boston. Our findings suggest that the urban gun violence epidemic, and sudden downturn in urban gun violence in the late 1990s, may be best understood by examining highly volatile micro-level trends at a relatively small number of places in urban environments.     

Psychiatrists,criminals, and the law: Forensic psychiatry in Switzerland 1850–1950

Between 1880 and 1950, Swiss psychiatrists established themselves as experts in criminal courts. In this period, the judicial authorities required psychiatric testimonies in a rising number of cases. As a result, more offenders than ever before were declared mentally deficient and, eventually, sent to psychiatric asylums. Psychiatrists also enhanced their authority as experts at the political level. From the very beginning, they got involved in the preparatory works for a nationwide criminal code. In this article, I argue that these trends toward medicalization of crime were due to incremental processes, rather than spectacular institutional changes. In fact, Swiss psychiatrists gained recognition as experts due to their daily interactions with judges, public prosecutors, and legal counsels. At the same time, the spread of medical expertise had serious repercussions on psychiatric institutions. From 1942 onwards, asylums had to deal with a growing number of “criminal psychopaths,” which affected ward discipline and put psychiatry's therapeutic efficiency into question. The defensive way in which Swiss psychiatrists reacted to this predicament was crucial to the further development of forensic psychiatry. For the most part, it accounts for the subdiscipline's remarkable lack of specialization until the 1990s.
