How does immigration enforcement affect public safety? Heightened enforcement could reduce crime by deterring and incapacitating immigrant offenders or, alternatively, increase crime by discouraging victims from reporting offenses. The researchers study the U.S. Secure Communities program, which expanded interior enforcement against unauthorized immigrants. Using national survey data, they find that the program reduced the likelihood that Hispanic victims reported crimes to police and increased the victimization of Hispanics. Total reported crimes are unchanged, masking these opposing effects. The researchers provide evidence that reduced Hispanic reporting is the key driver of increased victimization. Their findings underscore the importance of trust in institutions as a central determinant of public safety.

Racial disparity in arresting behavior is a significant concern for people of color. It also delegitimizes law enforcement, increases tension between police and citizens, and can even increase crime. Efforts at police reform stall, in part because racial disparity in policing was previously unmeasurable. The authors present three new measures of racial disparity in arrest, measured across more than 13,000 agencies nationwide, allowing for reliable analysis of disparity across time and geographic space. These measures are validated against Department of Justice law enforcement misconduct investigations, the “gold standard” for assessing racial disparity in policing.

Illicit trade of tobacco negatively affects countries’ tobacco control efforts. It leads to lower tobacco prices and makes tobacco products more accessible to vulnerable populations. In this study, we constructed an illicit tobacco trade index, which measures the structural and institutional capabilities of 160 countries in addressing illicit tobacco trade. We collected the most recent and best available data on general governance, tobacco control policies, and trade and customs practices. Singapore, New Zealand, Finland and Sweden lead countries with the most favorable illicit tobacco trade score. We observed a positive relationship between illicit tobacco trade scores and Gross National Income (GNI) per capita and a negative relationship with the share of illicit tobacco trade to total tobacco consumption. The capability to combat illicit trade varies across countries. However, on average, low and middle-income countries (LMICs) are less capable of addressing illicit tobacco trade as suggested by the lower illicit tobacco trade index score. The lower index score in low and middle-income countries was mainly driven by low scores in tobacco control policies and trade and customs practices and conditions. Our study reinforces the importance for LMICs to adopt the WHO’s Protocol to Eliminate Illicit Tobacco Trade Products, particularly committing to treaty obligations and investing on track and trace system and other customs reforms.

  This report summarizes the details of a problem analysis conducted by the International Association of Chiefs of Police/University of Cincinnati (IACP/UC) Center for Police Research and Policy (the “Center”) on domestic violence patterns for the Tulsa Police Department (TPD). The TPD identified domestic violence as an area requiring further understanding given the seriousness of the crime, and frequency as measured by citizen-generated calls for service. For the TPD, domestic violence-related incidents represent their third most frequent call for service, consuming substantial police resources. Prior to recommending an appropriate intervention strategy to reduce domestic violence, it is critical to better understand details regarding the specific domestic violence problem in Tulsa. For police agencies, a problem analysis includes the systematic examination of the underlying conditions of local problems they are tasked with solving. Problem analyses generally rely on information gathered from various sources, and should include examinations of both qualitative and quantitative data. The problem analysis process is critical for developing solutions that fit the problem in each community, because what works in one jurisdiction may not fit a similar problem in another setting (Boba, 2003). The following study documents a problem analysis based on a series of statistical analyses conducted on five-years of domestic violence data reported to the TPD (2013-2017) and victimization data gathered by the Family Service Center in Tulsa. Domestic violence is defined as an incidence of assault and battery against individuals connected to the suspect by one of fifteen different categories of relationship (see Oklahoma Statute §21-644). These variations in relationships cover both common (e.g. husband-wife or child-parent) and seemingly more distant (e.g. spouse-former spouse of partner or former roommate) relationships between individuals. Unfortunately, the automated data used by the TPD does not include a field for the relationship between the victim and offender. TPD data included reports for incidents, arrests, victims, calls for service, and field interview reports. These analyses were supplemented with domestic victimization data provided from the Family Service Center. The main findings of this problem analysis are summarized below. . Domestic violence-related calls for service were the third most frequent call received by the TPD (n=109,623; preceded by traffic stops and alarms) between 2013 and 2017. These reports were relatively stable over the five-year period, with an average of 21,942 calls per year. . Citizen-generated indicators of domestic violence (i.e. calls for service and incident reports) remained relatively stable over the five-year period, while the TPD-generated responses (i.e. FIR and arrest) to these crimes decreased noticeably over the same period of time. Arrests for domestic violence declined by 40.9% from 2013 to 2017, and FIRS similarly declined by 46.8% from 2013 to 2017.. TPD-generated incident reports indicate that 84.5% (n=13,381) of identified suspects were suspected of only committing one domestic violence offense, whereas 15.5% (n=2,447) were suspected of committing two or more offenses. . TPD-generated victimization reports indicate 83.8% (n=15,564) individuals were victimized once, and 16.2% (n=3,008) were victimized two or more times. . These findings demonstrate that the “repeat phenomenon” of domestic violence victimization in Tulsa is similar between victims and suspects. That is, victims are just as likely to be victimized more than once (16.2%) compared to offenders involved in more than one offense (15.5%). . Victimization data provided by the Family Safety Center indicates large increases in the number of services provided (180.6% increase) and the number of individuals receiving services (118.1% increase), likely due to the expansion of victim-services provided in Tulsa during the five-year study time period. Note that the increase of use of victim services is inconsistent with the downward trend in TPD domestic violence arrests. . Data from the FSC also indicates that the percentage of Black victims receiving FSC services (19.3%) was lower than expected given the victimization data captured by the TPD (31.6% for single incidents and 40.6% for repeat incidents), suggesting that Black domestic violence victims may be less likely to request or to receive services. . Analyses also show that 15.5% (n= 2,447) of the individuals suspected of domestic violence offenses were repeat offenders, and they accounted for 23.2% of the domestic violence incidents reported during the study period. . When offenders did commit a subsequent domestic violence offense for which an arrest occurred, the time between arrests was extremely long (an average of over 500 days). However, as the number of repeat domestic violence offenses increase per an offender, the number of days between these arrests decreases. Nonetheless, the average time between offenses is substantially long, indicating that focused deterrence approaches to repeat domestic violence offenders may not be effective in Tulsa (Sechrist, Weil, and Shelton, 2016).  Police data demonstrate that while a person was a victim in one incident, the same person was also commonly reported as the suspect in another domestic violence incident. Approximately 3,205 unique victims (17.2% of all domestic victims) were also charged as a suspect in a different domestic violence case.  Approximately 15% (8 out of 53) of offenders in domestic violence homicide incidents had a previous arrest for domestic violence.  A review of the relationship between the victim and suspect identified in the field interview reports indicates that the most common relationship type is current spouse/cohabitant (43.3%), followed by former spouse/cohabitant (20.3%), and dating (18.0%). Very few cases involve other types of relationships.  Field interview reports (FIR) revealed a substantial number of cases (36.7%), which involve the suspect threatening a future action—these represent an avenue for follow-up by TPD officer

As noted in the first installment of this One in Five series, scholars have declared a “generational shift” in the lifetime likelihood of imprisonment for Black men, from a staggering one in three for those born in 1981 to a still troubling one in five for Black men born in 2001. “I can’t breathe,” George Floyd said over 20 times. “Every time you see me, you want to mess with me,” said Eric Garner. “I just want to go home,” said Tyre Nichols. Breonna Taylor asked who had come into her apartment in the middle of the night. Police killed them all. The Black Lives Matter movement has rightly highlighted the tragic deaths resulting from policing’s biased and excessive contact with people of color. Nearly half of those killed by police in recent years have been Black or Latinx, and officers are rarely held accountable. This report interrogates the large footprint of policing—particularly of Black Americans— as, in part, a failed response to racial disparities in serious crimes. The wide net that police cast across people of color is at odds with advancing safety because excessive police contact often fails to intercept serious criminal activity and diminishes the perceived legitimacy of law enforcement. Excessive policing also distracts policymakers from making investments to promote community safety without the harms of policing and incarceration. In addition, the large footprint of policing gets in the way of, as the National Academies of Sciences has called for, needed “durable investments in disadvantaged urban neighborhoods that match the persistent and longstanding nature of institutional disinvestment that such neighborhoods have endured over many years.”

Background: Intimate Partner Violence (IPV) has transformed from a private matter into a global concern. Although progress has been made in enhancing police responsiveness to IPV, research on interventions in IPV cases involving children remains limited. Objective: This study investigates how police officers' responses vary depending on the nature and severity of IPV incidents and explores disparities in their responses when children are present at IPV incidents. Participants and setting: 175 police officers (126 males, 49 females) in a single Australian jurisdiction. Methods: A mixed-methods approach utilized an online survey with four hypothetical IPV scenarios to capture anticipated responses. The quantitative analysis assessed officers' recognition of incident seriousness and willingness to take action, while the qualitative thematic analysis explored reasons for response modifications in the presence of children. Results: The quantitative analysis revealed that officers consistently recognized the seriousness of IPV incidents and displayed a willingness to take various actions, such as initiating investigations and detaining perpetrators. Thematic analysis of qualitative data uncovered officers' reasons for modifying or maintaining their responses to IPV incidents with child presence. Concerns for child safety, emotional impact on children, and breaking the cycle of violence were identified as key drivers for officers' modified responses. Additionally, some officers adhered to standard procedures, emphasizing their legal obligations and the adequacy of their existing actions. Conclusions: This study contributes to an enhanced understanding of the complex decision-making processes among police officers when responding to IPV incidents involving children, highlighting the necessity of balanced policies and comprehensive training to navigate these complexities effectively.

Police accountability is essential to uphold the social contract. Monitoring the monitors is, however, not without difficulty. This paper reveals how police departments exploit specific laws surrounding death investigations to facilitate the underreporting of police killings. Our results show that US counties in which law enforcement can certify the cause of death, including counties which appoint the sheriff as the lead death investigator, display 46% more underreported police killings than their comparable adjacent counties. Drawing on a novel adapted-LATE potential outcomes framework, we demonstrate that underreported police killings are most often reclassified as 'circumstances undetermined' homicides. We also show that law enforcement agencies in counties with permissive death certification laws withhold more homicide reports from the public. The main underreporting results are primarily driven by underreporting of White and Hispanic deaths in our analysis sample, with the effect on Hispanic people particularly pronounced along the US-Mexico border. We do not find that excess underreported killings are associated with more violence directed towards police. We do, however, note a nationwide positive correlation between the permissiveness of gun-laws and underreported police killings. In addition, we find more underreporting in counties which have both high per-capita Google searches for Black Lives Matter and which allow law enforcement to certify the cause of death. Our results do not indicate that other differences in death investigation systems - coroner vs. medical examiner, appointed vs. elected, or physician vs. non-physician - affect the underreporting of police killings.

The authors undertook a literature review on intersectionality and policing to provide a critical, impact-based account of scholarly/academic engagement with policing and intersectionality. This review informs an intersectional good practice toolkit by which police organisations can better engage with the phenomenon of intersectionality and its implications for policing and ‘seldom heard communities’. Additionally, the authors hosted two interactive workshops to share preliminary findings, consult with academics and police practitioners and request feedback. The review highlighted that intersectional convergence of certain social identities and characteristics can provide complex challenges for policing, for example: The impact of micro-interactions between the police and those with intersecting social identities. Meso-level institutional issues may mitigate or aggravate negative interactions between the police and those with intersecting identities (such as police culture, resources, specialist training, and/or whether the police have specialist teams or programmes). Macro-level factors; the police operate under broader structural influences and power dynamics which negatively impact on certain groups, and which is informed by both historical and contemporary factors such as law, policy, political and public discourses and expectations.

Facial recognition technology is increasingly used for identity verification and identification, from aiding law enforcement investigations to identifying potential security threats at large venues. However, advances in this technology have outpaced laws and regulations, raising significant concerns related to equity, privacy, and civil liberties. This report explores the current capabilities, future possibilities, and necessary governance for facial recognition technology. Facial Recognition Technology discusses legal, societal, and ethical implications of the technology, and recommends ways that federal agencies and others developing and deploying the technology can mitigate potential harms and enact more comprehensive safeguards.

In April of 2023, the CPSC was contacted by the office of Mayor Sheng Thao to discuss the effectiveness of the current Ceasefire strategy, specific to the internal workings of the city. In essence, Mayor Thao wanted to know how and whether the City of Oakland was doing its part to implement the strategy effectively. She referred to a recommendation that was provided to the City of Oakland in a 2021 Problem Analysis conducted by Dr. Anthony Braga of the University of Pennsylvania and Dr. Lisa Barao of Westfield State University, where they stated: “It is recommended that the City of Oakland closely audits the resources allocated and activities of the organizations responsible for implementing Ceasefire. This audit will assess whether the challenges of the pandemic and demands for police reform have diminished focus. The audit should determine whether each key component (communications, service provision, law enforcement) has the necessary focus, quality, and scale to reduce the violence problem the city now faces.4” As a result of this recommendation and those discussions, Mayor Thao requested the CPSC to audit the current Ceasefire strategy. This audit is limited to the Ceasefire strategy and to the role of the Oakland Police Department, Department of Violence Prevention, and how they work with  their partners5, who are funded to provide services for those clients. This audit does not examine the role of community partners such as moral voices or outside agencies. Objectives of the audit: 1. To determine if the Ceasefire strategy is being implemented effectively. 2. To determine if Ceasefire is the appropriate strategy for Oakland’s current gun violence challenges. 3. To understand what is currently driving gun violence in Oakland. This includes an updated brief problem analysis that captures Oakland’s shootings and homicides from January 2023 to September 30, 2023.

The City of Oakland, California, has long suffered from very high levels of serious violence. According to the FBI’s Uniform Crime Reports, Oakland’s homicide rate (31.8 per 100,000) was almost 6.8 times higher than the national homicide rate (4.7 per 100,000) in 2012. That year, the City of Oakland engaged the California Partnership for Safe Communities (CPSC) to help design and implement a focused deterrence program to reduce serious gun violence. The CPSC collaborated with the Oakland Police Department (OPD) on ongoing problem analysis research to understand the underlying nature of gun violence in Oakland. The OPD led an interagency Ceasefire enforcement group comprised of federal, state, and county criminal justice agencies. The broader Oakland Ceasefire Partnership included the Mayor’s Office, social service agencies led by the Human Services Department, and community leaders from local organizations such as Oakland Community Organizations (OCO). The Oakland Ceasefire program closely followed the key elements of a focused deterrence Group Violence Reduction Strategy (GVRS). Briefly, GVRS programs seek to change offender behavior by understanding underlying crime‐producing dynamics and conditions that sustain recurring crime problems, and implementing a blended strategy of law enforcement, community mobilization, and social service actions. The Oakland Ceasefire program was fully implemented in early 2013. Between 2010 and 2017, total Oakland shooting victimizations peaked at 710 in 2011 (93 gun homicide victims and 617 non-fatal shooting victims) and decreased by 52.1 percent to a low of 340 in 2017 (63 gun homicide victims and 277 non-fatal shooting victims). The impact evaluation was designed to determine whether the Ceasefire intervention was associated with this steep decline in serious gun violence and assess how Ceasefire partners and community leaders perceived the implementation of the strategy.

On May 24, 2022, a mass shooting at Robb Elementary School in Uvalde, Texas, shook the nation. In the aftermath of the tragedy, there was significant public criticism of the law enforcement response to the shooting. At the request of the then mayor of Uvalde, the U.S. Department of Justice (DOJ) conducted a Critical Incident Review (CIR) of the law enforcement response to the mass shooting. In providing a detailed accounting and critical assessment of the first responder actions in Uvalde, and the efforts since to ameliorate gaps and deficiencies in that response, this report is intended to build on the knowledge base for responding to incidents of mass violence. It also will identify generally accepted practices for an effective law enforcement response to such incidents. Finally, it is intended to help honor the victims and survivors of the Robb Elementary School tragedy.

 This publication presents abbreviated case studies of large and small law enforcement agencies that have undergone or are currently conducting change initiatives to address a wide range of pressing issues common to law enforcement, such as backlogged sexual assault cases, lack of community trust, inadequate information and intelligence sharing, and increases in violent or juvenile crime. These issues and others prompted change initiatives among the 13 agencies interviewed for this resource. In September 2022, executives from several of the case study agencies met in Washington, D.C., for a working session to provide additional insights learned through the change experience (see appendix A for a list of roundtable attendees). The experiences of these agencies are documented in this publication with the hope that law enforcement executives and managers will find the strategies, actions, and lessons learned helpful in adapting to changes in their internal and external environments.

Key Points

• Despite pursuing a similar goal, the “what works” and desistance literatures have largely ignored and undervalued the contributions the other has made.

• The what works literature has been mostly quantitative and has consisted of program evaluations and meta-analyses, leading to the emergence of principles of effective correctional intervention and the risk-needs-responsivity model.

• The desistance literature has been more qualitative and has focused on persons rather than correctional programs, stressing the importance of identity transformation in the desistance process.

• Correctional systems do not provide “desistance opportunities”—programs, interventions, and services—to the extent they are needed. Programs should become more person-centered by placing a greater emphasis on identity transformation.

Background: The violent behavior of football fans is constantly associated with their drinking habits. Aiming to reduce its impact, policy makers often ban the sales and consumption of alcohol beverages during matches. Nonetheless, there are few papers that empirically analyzed such relationship, and our paper aims to shed light on this question. Methods: Out dataset comprises 4,560 matches from the first and second tiers of the Brazilian League, where 245 exhibited at least one antisocial behavior from fans. Ordered logistic regressions are used as method. Results: Our empirical findings evidence that the sales of alcoholic drinks do increase the likelihood of severe antisocial behavior. We also observed a higher likelihood of violent cases when the home club loses its match as well as during crowded matches. Conclusions: We conclude that the change in the alcohol police in Brazil did show a significant association with the likelihood of antisocial behavior among football fans. However, since the magnitude of such effect is small, further research is needed to examine the potential benefits of this policy changes

Key Points

• The nation’s unemployment benefits system, which was significantly expanded during the COVID-19 pandemic, suffered unprecedented losses to fraud and improper payments.

• Official—and still partial—estimates of improper payments approach $200 billion, while unofficial estimates suggest $400 billion or more may have been lost.

• There are multiple causes of these record improper payments, including historically large benefits, poor program design including eligibility self-certification in new programs, and degraded administrative systems without adequate defenses against various fraudulent schemes.

• State and federal policymakers should review the causes and consequences of these unprecedented losses and take specific steps, such as those outlined in this report, to both prevent a recurrence of the record taxpayer losses experienced during the pandemic and better establish a proactive anti-fraud posture for the unemployment insurance system.

There is increasing pressure for the juvenile criminal legal system to address trauma; this is in response to advances in the science of trauma and adversity, evidence from interventions showing promising outcomes for juveniles coping with trauma, and development of systemic frameworks for providing trauma-informed care. This review details how exposure to potentially traumatic events can create primary, secondary, and tertiary effects that are relevant to how the criminal legal system engages with juveniles coping with trauma. Associations that could be dismissed on methodological challenges can no longer be ignored as an increasingly sophisticated body of prospective studies replicate previous cross-sectional and retrospective studies, which found a higher prevalence of trauma among system-involved juveniles and show that exposure to potentially traumatic events and trauma symptoms play causal roles in engaging in behaviors that can be classified as criminal offending. Additionally, several examples are used to illustrate how racialized exposure to systemic trauma across generations underlies racialized disparities in persistent criminal offending—over exposure to potentially traumatic events and underexposure to coping resources. A broad range of developmental and criminological research is drawn upon to provide frameworks for implementing trauma-informed care as a systemic intervention aimed at minimizing retraumatization and using every interaction that juveniles have with the criminal legal system to contribute to recovery and prevent recidivism.
