News Reporting on Human Trafficking: Exploratory Qualitative Interviews with Illinois News Journalists
January 16, 2018 | Article | Victims
Media—in particular news coverage—contribute toward shaping public understanding and opinion on societal issues, and influence policies, programs, and legislative action. While a small number of previous studies have explored journalists’ reporting on other social issues, very little is known about their perceptions and knowledge of human trafficking. In this exploratory study, researchers conducted 12 qualitative interviews with Illinois newspaper reporters to examine their understanding and work process in covering human trafficking. The results suggest that while many reporters understand the federal definition of trafficking, there remain gaps in knowledge about the complexity of the issue. Furthermore, the work process that reporters follow to report on human trafficking differs by their particular role and level of experience, with investigative stories on human trafficking being covered by more seasoned reporters who have the time and space to explore the issue in greater depth. The study findings highlight the importance of, and constraints upon, comprehensive news coverage on human trafficking.

Comprehensive Legal Services for Victims of Crime
December 13, 2017 | Article | Victimization
Illinois victims and victim service providers indicate that legal services are needed post-victimization, and for many victims in the state this need is left unmet. Meeting a victim’s legal needs is key to ensuring their safety and security and enabling them to continue to recover from their victimization experience. Crime victims can directly benefit from access to comprehensive legal services, including legal advocacy, civil legal services and victim rights enforcement. Numerous legal avenues are open to victims of crime, and legal advocates and attorneys are well-positioned to assist victims as they engage either the criminal justice or civil legal systems. This article explores types of victim legal services, the roles of legal service providers, the needs and potential remedies available to victims by crime type, and barriers to legal service access and delivery. Implications for both providers and funders to ensure comprehensive legal services to victims of crime also are discussed.

An Overview of Problem-Solving Courts and Implications for Practice
December 11, 2017 | Article | Courts
Problem-solving courts have operated as separate courts or dockets as an alternative to adjudication or incarceration for more than 20 years. These programs offer clients court accountability, intensive supervision, drug testing, and treatment for substance use disorders, mental health conditions, and other issues. Drug, mental health, domestic violence, and veteran’s courts are the most common problem-solving models, with 3,000 in existence around the country. This article provides a state and national overview of problem-solving courts, components shown to reduce recidivism and increase public safety, and implications for policy and practice.

Evaluation of Illinois Multi-Jurisdictional Drug Task Forces
December 6, 2017 | Research Report | Law Enforcement
Drug trafficking constitutes a major threat to public health and community well-being. Multi-jurisdictional drug task forces, comprised of law enforcement officers in one or more counties that agree to pool resources, were designed to combat drug distribution and trafficking. Researchers evaluated 19 drug task forces in Illinois using quantitative and qualitative methods. Quantitative methods included analyzing administrative data and state arrest records. Qualitative methods included focus groups with members of 18 task forces and surveys of both staff and policy board directors. The study revealed Illinois drug task forces made proportionately more drug arrests carrying more serious felony and manufacture/delivery charges than their local police counterparts. The study also showed the task forces fostered collaboration with stakeholders, maintained fidelity to critical elements of drug task forces, and garnered support from their policy boards.

Exploring Effective Post-Opioid Overdose Reversal Responses for Law Enforcement and Other First Responders
November 29, 2017 | Article | Law Enforcement
First responders across the country are carrying and administering naloxone, successfully reversing countless overdose deaths. However, experiencing a revival isn’t always a deterrent for those suffering with opioid use disorder, as many continue to use, experience repeated overdoses, and repeatedly come into contact with local law enforcement. Some police officers are beginning to experience frustration with repeated calls for revival, as well as continued and frequent contacts with and arrests of the same individuals. Communities are learning overdose reversal is just the first step in opioid intervention. With opioid deaths on the rise and fentanyl deaths rapidly increasing, a crisis of this magnitude requires innovative responses at multiple intervention points, including post-overdose, as part of a comprehensive strategy to aid in the treatment of and recovery from opioid use disorders. This article explores law enforcement overdose reversal and post-resuscitation and treatment responses in the newly emerging field of pre-arrest diversion.

Procedural Justice in Policing: How the Process of Justice Impacts Public Attitudes and Law Enforcement Outcomes
November 7, 2017 | Article | Law Enforcement
An increasing number of widely publicized and divisive incidents between police and citizens suggest a need for police policies and practices to improve procedural justice. Procedural justice emphasizes the need for police to demonstrate their legitimacy to the public in four areas—voice, transparency, fairness, and impartiality. This article explains procedural justice and police legitimacy, examines the often racial divide between citizens and police, and offers implications for police policy and practice.

Crime & Risk Factor Data Tools

With support from the U.S. Department of Justice, Bureau of Justice Statistics, ICJIA has developed several data analysis and dissemination tools to give users convenient and flexible ways to access and interact with ICJIA’s extensive criminal justice and associated risk factor data holdings.

Criminal Justice Data Profiles

The Criminal Justice Data Profiles tool offers criminal justice indicators that allow users to create county, judicial circuit, and statewide profiles. These profiles may be used to inform planning and policy decisions.

Criminal Justice Data Profiles 

Criminal history and recidivism tool

The Criminal History and Recidivism Tool provides information on the patterns of prior criminal history of various cohorts of persons sentenced to prison in Illinois, and their long-term recidivism rates upon release. Tables and charts display several types of information: demographic information on the selected group of interest; the number and types of prior arrests, convictions, probation and prison sentences; and post-release recidivism rates based on multiple types of criminal justice events and demographic categories.

Criminal History and Recidivism Tool 

Single Map Analysis Tool

The Single Map Analysis Tool is useful for those interested in a visual snapshot of how Illinois counties compare on various crime and criminal justice indicators. The tool displays this information in two interactive formats; as an Illinois map, and as corresponding trend lines over the previous ten years. Users can select any number of counties, regions or judicial circuits for comparison.

Single Map Analysis Tool 

Scatter Plot Analysis Tool

The Scatter Plot Analysis Tool allows users to compare the relationship between two different criminal justice indicators within a county, and determine how all Illinois counties rank on that joint set of crime statistics or criminal justice indicators. The tool displays this information in several interactive formats; as Illinois maps and as a corresponding scatter plot showing correlations for all counties or custom sets of counties in Illinois.

Scatter Plot Analysis Tool 

These tools come with a variety of built-in Help features to assist users as they navigate the unique analysis functions.
