Objectives: The group based violence intervention model is predicated on the assumption that individuals who are delivered the deterrence message spread the message to the remaining group members. We focus on the problem of who should be given the initial message to maximize the reach of the message within the group. Methods: We use social network analysis to create an algorithm to prioritize individuals to deliver the message. Using a sample of twelve gangs in four different cities, we identify the number of members in the dominant set. The edges in the gang networks are defined by being arrested or stopped together in the prior three years. In eight of the gangs we calculate the reach of observed call-ins, and compare these with the sets defined by our algorithm. In four of the gangs we calculate the reach for a strategy that only calls-in members under supervision. Results: The message only needs to be delivered to around 1/3 of the members to reach 100% of the group. Using simulations we show our algorithm identifies the minimal dominant set in the majority of networks. The observed call-ins were often inefficient, and those under supervision could be prioritized more effectively. Conclusions: Group based strategies should monitor their potential reach based on who has been given the message. While only calling-in those under supervision can reach a large proportion of the gang, delivering the message to those not under supervision will likely be needed to reach 100% of the group.

Unwarranted, by NYU law professor Barry Friedman, offers a diagnosis of some of the contemporary ills of American policing and a prescribed cure. Between 2014 and 2016, incidents of fatal shootings...

By most contemporary accounts, the judgments that people make about their contacts with the police have a strong bearing on their broader attitudes toward the police, including especially their tru...

Academics and practitioners recognize that research partnerships can benefit both research and practice. Many such partnerships, of varying scope and duration, have been formed over the past 20 years. However, while we have learned some lessons about such partnerships, we have much yet to learn about how research partnerships can be sustained and put to their greatest use. In this paper, we describe the functions that comprise the research partner role, and we draw from our experience as a research partner in one city – Syracuse, NY – to illustrate the performance of those functions and to reflexively distill from that experience some lessons for the development and maintenance of research partnerships. We discuss the factors that we believe shaped the success with which the partnership has operated, and the challenges that we confronted.

According to the conventional wisdom, the police culture consists of a set of values, attitudes, and norms that are widely shared among officers, who find in the culture a way to cope with the strains of their working environment. Some research implies that the conventional wisdom is overdrawn, and recent research has begun to question it more directly. Changes in the composition (i.e., the race, sex, and education) of police personnel, as well as philosophical and organizational changes associated with community policing, could be expected to further fragment police culture and to shift the distribution of police attitudes. Here we examine variation in outlooks that, according to conventional wisdom, are part of the police culture, using survey data collected in two police departments. We also examine the relationships between these outlooks and characteristics of officers—sex, race, education, length of service, community-policing training, and community-policing specialist assignment—that are associate...

Recent research has reexamined the hypothesis that suspects' demeanor affects police behavior. Reanalyses have supported this demeanor hypothesis, but none have considered the possible interaction effect of demeanor with other extralegal variables. Utilizing systematic observational data collected in 24 police departments in three metropolitan areas, this research examines whether demeanor and suspects' characteristics interact, and ultimately produce differential patterns of citation, arrest, and the use of force. These estimated interaction effects provide a clearer understanding of the effect of demeanor in different contexts; more important, they acknowledge that officers accept some forms of disrespect but not others, depending on factors outside demeanor alone.

It is often implied that citizens’ attitudes toward the police are a determinant of their willingness to engage in the coproduction of police outputs. This relationship, however, has been subjected to only limited empirical scrutiny. Using data from a three wave panel survey conducted in a large metropolitan area, this study examines the determinants of coproduction with particular emphasis on the causal role of citizens’ attitudes toward the police. The study provides little support for the hypothesis which links citizens’ attitudes to citizen willingness to engage in coproductive behaviors. Instead, a variety of other individual level variables appear to have a much greater effect on citizen willingness to engage in coproductive behaviors.

Since the 1960s, a substantial body of research has focused on citizens' attitudes toward the police. These studies tap a rather wide variety of outlooks: some ask about specific assessments of the police (e.g., satisfaction with the police in particular incidents), while others ask about more global assessments (e.g., satisfaction with the police in general, police in the community, or police in the neighborhood). Using data obtained through a panel survey of 398 residents of a large midwestern city, we compare specific assessments of police performance with more global attitudes toward the police. We also examine the effects of global and specific attitudes on one another. The results show that the two measures produce similar levels of support for the police. The results reveal further that global attitudes have substantial effects on specific assessments of police performance, and that the effects of specific assessments of police performance on global attitudes are modest by comparison.

Arguments for and against measures intended to raise the educational levels of police officers turn partly on the hypothesized relationships between college education and officers' attitudes and behavior. The purpose of this analysis is to provide additional empirical evidence concerning these hypotheses. The results suggest that college education is weakly related to some attitudes and unrelated to others. The results also show that officers' performance in police-citizen encounters, measured in terms of citizens' evaluations, is largely unrelated to officers' educational backgrounds.
