The vision of the Community Restorative (CORE) Health Project was to increase awareness and availability of trauma-informed care and indigenous healing practices in the target communities for clients and families being served by the City of Los Angeles Mayor's Office of Gang Reduction and Youth Development (GRYD). Two agencies were contracted to provide either trauma-focused mental health treatment or training on indigenous healing practices to clients, families, and the community. A total of 115 individual or group therapy sessions were provided, 23 community based workshops on trauma-informed care or indigenous healing practices were offered, and 15 professional development events were attended by over 354 GRYD intervention workers or CORE staff.

Background information was collected during the initial stages of the GRYD program, and a youth's eligibility for GRYD services was determined. The Posttraumatic Screening Inventory was used to assess the presence of posttraumatic stress, exposure to a traumatic event, and whether participants should be referred for treatment. Youths were then exposed to the GRYD's Summer Night Lights program, which raised trauma awareness, taught coping strategies, and increased access to services.

Then the National Compadres Network was chosen to administer three training sessions on indigenous healing practices: La Cultura Cura, El Joven Noble, and Circle Keepers. Pre-test surveys collected demographics such as age, gender, ethnicity, and religiosity, as well as their expectations heading into training. Post-test surveys assessed how much information participants received, the usefulness of information, if training rationale made sense, and whether or not participants planned to use what they had learned. After training sessions were completed, researchers conducted 10 follow up interviews with services providers and leadership from CORE.

The data was used to provide estimates of the effects of a Los Angeles letter program on citywide levels of homicide, robbery, and aggravated assault with a firearm. This study will provide the city of Los Angeles and other jurisdictions in California (and beyond) with information on the impact and cost-effectiveness of an innovative gun letter program. This project involves the following:

• statistical analysis of gun-level data to assess program impact on reporting guns lost or stolen,
• statistical analysis to evaluate the impact of the program on city-level crimes involving a firearm, and
• assessment of program costs.

Research about ethnocultural influences on women's experience of and response to intimate partner violence (IPV) is scarce, contributing to culturally incongruent processes that may deter some survivors from engaging with community systems. To fill this gap in the literature, this project examined the ways that cultural beliefs and contexts serve as a lens through which European-American, Mexican-American, Korean-American, and Vietnamese-American women experience and respond to IPV in their lives. Community-based recruitment techniques were used to recruit female survivors of intimate partner violence from the four target ethnic groups. Data collection included qualitative interviews (n = 112) and online surveys (n = 193) with survivors of intimate partner violence as well as focus groups with service providers (n = 37). While there were many shared experiences across survivors from the four ethnic groups, important differences in survivors' interpretation of abuse, strategies for managing the abuse, and help-seeking experiences did emerge. These differences have important implications for the development of culturally competent prevention and intervention strategies for survivors from different ethnic groups.

This collection only contains the online survey data. The focus group and individual interview data will be released at a future date.

This study evaluated the cost effectiveness of the Los Angeles Elder Abuse Forensic Center (EAFC) by examining costs associated elder abuse cases processed under a multidisciplinary team approach. Using data collected in Evaluating the Elder Abuse Forensic Center Model in Los Angeles County, California, 2007-2009 (ICPSR 34979) researchers focused on the key components, participants, and processes necessary to operate the Los Angeles EAFC and identified the costs required to process an elder abuse case as well as the outcomes attained by the EAFC. This study also carried out a survey of Adult Protective Service (APS) social workers on time spent on different case process activity and their perception on efficiency of the Los Angeles EAFC, and collected associated costs estimates.

The purpose of the study was to examine the effectiveness of a multidisciplinary team (MDT) intervention - the Los Angeles County Elder Abuse Forensic Center to: 1) prosecute elder abuse, 2) protect vulnerable older adults through conservatorship, and 3) reduce or prevent recurring cases of abuse. The study used a quasi-experimental design and focused on elder abuse cases involving victims aged 65 or older reviewed at the Los Angeles County Elder Abuse Forensic Center (the Center) between April 1, 2007 and December 31, 2009. These Center cases were compared to a propensity score match sample of Los Angeles County Adult Protective Services (APS) cases. Data were collected from Adult Protective Services case files, District Attorney filings, and Office of the Public Guardian conservatorship records.

The Office for Victims of Crime (OVC) created a new demonstration grant program, the OVC Wraparound Victim Legal Assistance Network Demonstration Project, to address the wide range of legal needs victims of crime have in relation to the victimization they experienced. The original four-year demonstration, which was increased to six years, included two phases: (1) a 15-month phase for planning, designing a new service delivery model in collaboration with local partners, and conducting a needs assessment, and (2) a second phase for grantees to implement the model as designed. The program originally funded six sites to plan and implement a new model of legal assistance for victims:

1. Alaska Immigrant Justice Center (entire state of Alaska)
2. Council on Crime and Justice (entire state of Minnesota)
3. Legal Aid Foundation of Los Angeles (Los Angeles County, California)
4. Lone Star Legal Aid (72 counties in East Texas)
5. Metropolitan Family Services' Legal Aid Society (Cook County, Illinois)
6. Rocky Mountain Victim Law Center (City of Denver, Colorado)

The new wraparound service delivery models were expected to facilitate the implementation of wraparound pro bono legal assistance networks to provide legal services to victims. Because victims often receive legal services from a variety of uncoordinated organizations (e.g., victim legal clinics for help with enforcing rights, and legal aid offices or law school clinics for help with other specific civil legal needs), integrated networks may be better able to provide a wide array of legal services from a single, coordinated system. The demonstration grant requirements included: creating and actively engaging a steering committee, working cooperatively with technical assistance provider(s) as needed, and employing a local research partner to help perform the needs assessment and work closely with the evaluation team.

This study sought to: (1) document the spectrum of injuries and injury characteristics observed among physically-abused older adults reported to Adult Protective Services (APS) and compare those findings to injuries found among non-abused older adults, (2) identify observable injury characteristics and abuse circumstances that healthcare providers, law enforcement and prosecutors consider to be key forensic markers of physical abuse, (3) document information and evidence integral for achieving successful criminal prosecution, and (4) describe approaches that community-based frontline workers can employ to better document evidence of physical abuse.

The data included in this collection were collected under a National Institute of Justice-funded project that sought to document the spectrum and characteristics of injuries observed among physically abused, community-dwelling APS clients.

The collection includes two SAS datasets: injury.sas7bdat (with 47 variables and 403 cases) and subjectleveldata.sas7bdat (with 122 variables and 165 cases); and three SAS System Program Files: analysis-code-v1.sas, cleaned-injury-datasets-v1.sas, and formats.sas. Demographic variables in the collection are in the subjectleveldata.sas7bdat dataset, and include age, year of birth, gender, race, language, and level of education.

In 2018 Justice and Security Strategies, Inc. (JSS) recieved funding from the National Institute of Justice (NIJ) to code and analyze detailed homicide data collected by the Los Angeles Police Department (LAPD). The data in this study were compiled from the LAPD's digitized homicide casefiles, or Murder Books, stored at the Homicide Library. These digitized casefiles included relevant information from the chronological log of detective activity, crime scene log, first responder statements and officer reports, incident history from the CAD and 911 tapes, Los Angeles Fire Department medical service report, death/autopsy report, suspect arrest report, evidence reports, follow-up reports, investigator final report, search warrants, crime scene sketches, crime scene notes, scientific evidence analysis, witness statements and notes, suspect interview notes, and case status information. A total of 4,111 Murder Books detailing homicides from four of 21 LAPD area stations in South Los Angeles between 1990 to 2010 were digitally scanned and preserved for posterity. Through a grant from the National Institute of Justice, JSS researchers 'tagged' the data to facilitate sharing these Murder Books among detectives in the South Bureau. These 'tags' also serve to encode features and outcomes from the Murder Book case files.

The data archived from this project consist of the digital database of the tagged Murder Books. There are two files included in this project. The victim file contains information about both the incident (obtainable from unique incident numbers) and information about the victim (victim number associated with each incident). The suspect file contains information about the suspects associated with each incident and can be linked to the original incident through the incident number.

Financial elder exploitation (FE) is an increasing problem for vulnerable elders exploited by opportunists and for the social service and criminal justice system designed to protect them. This study systematically investigated both objective and subjective measures of social support and isolation, along with common risk factors mentioned in FE theories, including dependency, physical health, depression, cognition, and demographic characteristics. Researchers collected data on individual difference variables with an emphasis on cognitive factors and data on contextual factors using an individually administered survey approach. The framework for this project was derived from known factors for FE, predicted protective factors for FE, and conceptual approaches from the child mistreatment literature on risk and resilience.

The study includes 1 SPSS data file with 216 cases and 297 variables.

The Interpersonal Violence and Institutional Misconduct in Jails Study is a longitudinal evaluation of administrative data collected from the Los Angeles County Jail System. This study includes aggregate monthly information on the number and rate of incidents of interpersonal violence and serious institutional misconduct in the Los Angeles County Jail System over an eight-year time period (January 2010 to December 2017). This investigation also includes information on the development and validation of two separate risk assessment tools--the Inmate Risk Assessment for Perpetration (IRAP) and the Inmate Risk Assessment for Victimization (IRAV)--that were designed to help authorities proactively identify the perpetrators and victims of interpersonal violence in jail, respectively. The subjects used to construct and test these instruments were an admission cohort of all adjudicated inmates entering the Los Angeles County jail system in 2016 (N = 104,919). This population of inmates was randomly assigned into one of four groups. The first was the construction sample (n = 26,404), which was used to create the two risk assessment scales, and the other three served as cross-validation samples, which each served to evaluate the predictive accuracy and reliability of these instruments. These data include individual-level information on inmate demographics, criminal history, and other measures of institutional behavior.

This research was an evaluation of the Los Angeles Police Department's (LAPD) Training Evaluation and Management System II (TEAMS II) Early Intervention System conducted by Justice and Security Strategies, Inc. TEAMS II was designed to identify officers at-risk for engaging in future problematic behavior. This system was mandated as part of the Consent Decree (Section II) that was formally entered into on June 15, 2001 between the U.S. Department of Justice and the LAPD. Justice and Security Strategies, Inc. research staff worked with the Information Technology Bureau to obtain and analyze TEAMS II data, conducted informal interviews with officers, sergeants, civilians, command staff, and technologists involved with TEAMS II, and worked with the TEAMS II contractors to examine and provide recommendations.

Demographic variables included as part of this data collection include officer age, gender, ethnicity, education level, and total number of officers employed by demographics.

This study examines the state of counterterrorism and homeland security in five large urban law enforcement agencies (the Boston Police Department, the Houston Police Department, the Las Vegas Metropolitan Police Department, the Los Angeles County Sheriff's Department, and the Miami-Dade Police Department) nine years following the September 11, 2001, terrorist attacks. It explores the long-term adjustments that these agencies made to accommodate this new role.

Researchers from the RAND Corporation, in consultation with National Institute of Justice project staff, selected law enforcement agencies of major urban areas with a high risk of terrorist attacks from different regions of the United States that have varied experiences with counterterrorism and homeland security issues. The research team conducted on-site, in-depth interviews with personnel involved in developing or implementing counterterrorism or homeland security functions within their respective agency. The research team used a standardized interview protocol to address such issues as security operations, regional role, organizational structures, challenges associated with the focus on counterterrorism and homeland security issues, information sharing, training, equipment, and grant funding.

Using multiple data time points this study investigated the prospective validity of a secondary gang prevention program called Gang Risk of Entry Factors (GREF) assessment. At Time 1 of the study interview cut-points were established for high and low risk on nine risk factors that were included on the assessment. Those who scored high risk on four or more risk factors were determined eligible for secondary prevention. At time 2 each participate was then classified into one of four levels of gang membership. The goal of this was to investigate how successful the GREF was in identifying the youth (in the absence of a program) who become associated with a street gang in the 12 to 18 months of the study time frame .

This study used a mixed-methods approach to pursue five interrelated objectives: (1) to document the extent of case attrition and to identify the stages of the criminal justice process where attrition is most likely to occur; (2) to identify the case complexities and evidentiary factors that affect the likelihood of attrition in sexual assault cases; (3) to identify the predictors of case outcomes in sexual assault cases; (4) to provide a comprehensive analysis of the factors that lead police to unfound the charges in sexual assault cases; and (5) to identify the situations in which sexual assault cases are being cleared by exceptional means. Toward this end, three primary data sources were used: (1) quantitative data on the outcomes of sexual assaults reported to the Los Angeles Police Department (LAPD) and the Los Angeles County Sheriff's Department (LASD) from 2005 to 2009, (2) qualitative data from interviews with detectives and with deputy district attorneys with the Los Angeles District Attorney's Office who handled sexual assault cases during this time period, and (3) detailed quantitative and qualitative data from case files for a sample of cases reported to the two agencies in 2008.

The complete case files for sexual assaults that were reported to the Los Angeles Police Department and the Los Angeles County Sheriff's Department in 2008 were obtained by members of the research team and very detailed information (quantitative and qualitative data) was extracted from the files on each case in Dataset 1 (Case Outcomes and Characteristics: Reports from 2008). The case file included the crime report prepared by the patrol officer who responded to the crime and took the initial report from the complainant, all follow-up reports prepared by the detective to whom the case was assigned for investigation, and the detective's reasons for unfounding the report or for clearing the case by arrest or by exceptional means. The case files also included either verbatim accounts or summaries of statements made by the complainant, by witnesses (if any), and by the suspect (if the suspect was interviewed); a description of physical evidence recovered from the alleged crime scene, and the results of the physical exam (Sexual Assault Response Team (SART) exam) of the victim (if the victim reported the crime within 72 hours of the alleged assault). Members of the research team read through each case file and recorded data in an SPSS data file. There are 650 cases and 261 variables in the data file. The variables in the data file include administrative police information and charges listed on the police report. There is also information related to the victim, the suspect, and the case.

Datasets 2-5 were obtained from the district attorney's office and contain outcome data that resulted in the arrest of a suspect. The outcome data obtained from the agency was for the following sex crimes: rape, attempted rape, sexual penetration with a foreign object, oral copulation, sodomy, unlawful sex, and sexual battery.

Dataset 3 (Sexual Assault Case Attrition: 2005 to 2009, Los Angeles Police Department - Adult Arrests) is a subset of Dataset 2 (Sexual Assault Case Attrition: 2005 to 2009, Los Angeles Police Department - All Cases) in that it only contains cases that resulted in the arrest of at least one adult suspect. Dataset 2 (Sexual Assault Case Attrition: 2005 to 2009, Los Angeles Police Department - All Cases) contains 10,832 cases and 29 variables. Dataset 3 (Sexual Assault Case Attrition: 2005 to 2009, Los Angeles Police Department - Adult Arrests) contains 891 cases and 45 variables.

Similarly, Dataset 5 (Sexual Assault Case Attrition: 2005 to 2009, Los Angeles Sheriff's Department - Adult Arrests) is a subset of Dataset 4 (Sexual Assault Case Attrition: 2005 to 2009, Los Angeles Sheriff's Department - All Cases) in that it only contains cases that resulted in the arrest of at least one adult suspect. Dataset 4 (Sexual Assault Case Attrition: 2005 to 2009, Los Angeles Sheriff's Department - All Cases) contains 3,309 cases and 33 variables. Dataset 5 (Sexual Assault Case Attrition: 2005 to 2009, Los Angeles Sheriff's Department - Adult Arrests) contains 904 cases and 47 variables.

This study investigates experiences surrounding hate and bias crimes and incidents and reasons and factors affecting reporting and under-reporting among youth and adults in LGBT, immigrant, Hispanic, Black, and Muslim communities in New Jersey and Los Angeles County, California.

The collection includes 1 SPSS data file (QB_FinalDataset-Revised.sav (n=1,326; 513 variables)). The collection also contains 24 qualitative data files of transcripts from focus groups and interviews with key informants, which are not included in this release.

This research sought to evaluate the implementation of body worn cameras (BWCs) in the Los Angeles Police Department (LAPD). Researchers employed three strategies to evaluate the impact of BWCs in the department: 1) two-wave officer surveys about BWCs, 2) two-wave Systematic Social Observations (SSOs) of citizen interactions from officer ride-alongs, and 3) a time series analysis of existing LAPD data of use of force and complaint data.

The officer surveys were conducted in the Mission and Newton divisions of the LAPD before and after BWCs were implemented. The survey instrument was designed to measure perceptions of BWCs across a variety of domains and took approximately 20 minutes to complete. Researchers attended roll calls for all shifts and units to request officer participation and administered the surveys on tablets using the Qualtrics software. The pre-deployment survey was administered in both divisions August and September 2015. The post-deployment surveys were conducted with a subset of officers who participated in the pre-deployment surveys during a two-week period in the summer of 2016, approximately nine months following the initial rollout of BWCs.

The SSO data was collected in the Mission and Newton divisions prior to and following BWC implementation. The pre-administration SSOs were conducted in August and September 2015 and the post-administration SSOs were conducted in June and August, 2016. Trained observers spent 725 hours riding with and collecting observational data on the encounters between officers and citizens using tablets to perform field coding using Qualtrics software. A total of 124 rides (71 from Wave I and 53 from Wave II) were completed between both Newton and Mission Divisions. These observations included 514 encounters and involved coding the interactions of 1,022 citizens, 555 of which were deemed to be citizens who had full contact, which was defined as a minute or more of face-time or at least three verbal exchanges.

Patrol officers (including special units) for ride-alongs were selected from a master list of officers scheduled to work each day and shift throughout the observation period. Up to five officers within each shift were randomly identified as potential participants for observation from this master list and observers would select the first available officer from this list. For each six-hour observation period, or approximately one-half of a shift, the research staff observed the interactions between the assigned officer, his or her partner, and any citizens he or she encountered. In Wave 2, SSOs were conducted with the same officers from Wave 1.

The time series data were obtained from the LAPD use of force and complaint databases for each of the 21 separate patrol divisions, a metropolitan patrol division, and four traffic divisions of the LAPD. These data cover the time period where BWC were implemented throughout the LAPD on a staggered basis by division from 2015 to 2018. The LAPD operates using four-week deployment periods (DPs), and there are approximately 13 deployment periods per year. These data span the period of the beginning of 2012 through the 2017 DP 12. These data were aggregated to counts by deployment period based on the date of the originating incident. The LAPD collects detailed information about each application of force by an officer within an encounter. For this reason, separate use of force counts are based on incidents, officers, and use of force applications. Similarly, the LAPD also collects information on each allegation for each officer within a complaint and public complaint counts are based on incidents, officers, and allegations.

In the United States, a number of challenges prevent an accurate assessment of the prevalence of hate crimes in different areas of the country. These challenges create huge gaps in knowledge about hate crime--who is targeted, how, and in what areas--which in turn hinder appropriate policy efforts and allocation of resources to the prevention of hate crime. In the absence of high-quality hate crime data, online platforms may provide information that can contribute to a more accurate estimate of the risk of hate crimes in certain places and against certain groups of people. Data on social media posts that use hate speech or internet search terms related to hate against specific groups has the potential to enhance and facilitate timely understanding of what is happening offline, outside of traditional monitoring (e.g., police crime reports). This study assessed the utility of Twitter data to illuminate the prevalence of hate crimes in the United States with the goals of (i) addressing the lack of reliable knowledge about hate crime prevalence in the U.S. by (ii) identifying and analyzing online hate speech and (iii) examining the links between the online hate speech and offline hate crimes.

The project drew on four types of data: recorded hate crime data, social media data, census data, and data on hate crime risk factors. An ecological framework and Poisson regression models were adopted to study the explicit link between hate speech online and hate crimes offline. Risk terrain modeling (RTM) was used to further assess the ability to identify places at higher risk of hate crimes offline.
