This report compares arrestees in three categories of probation history – never served probation (or not in the past 12 months), served probation in a county other than Maricopa, and served probation in Maricopa County, each defined for either lifetime or the past 12 months, ultimately yielding six analysis categories. Each of the three probation categories are mutually exclusive within a given time period (i.e. lifetime and past 12 months). Given the Department’s need for the broadly scoped analysis as opposed to a topically-focused and interpretive report, the report here primarily provides analyses across most of the core instrument elements, presented in tabular form, with a list of key findings and highlights.

The purpose of this report is to provide a proof of concept for a different, alternative method for evaluating police agencies. Our method is couched in a comparative approach, which will allow agencies to compare their performance to other police agencies. This report assesses police performance through the perceptions and experiences of recently booked arrestees. By comparing the perceptions and experiences of recently booked arrestees from different jurisdictions we can begin to contextualize results and observe differences that might serve as an early warning of a problem or serve as an indicator of success.

The analysis plan and the format of this report are derived from numerous meetings held over more than an eighteen month span with the AARIN project advisory board, Maricopa County leadership, and representatives from MCSO. Following the guidance of the advisory board, the dissemination strategy for the AARIN project shifted from a single, broadly scoped annual summary report supplemented by smaller topic-specific reports into shorter, individual reports tailored to the specific needs and wants of six key county criminal justice agencies. Meetings with MCSO representatives regarding their individualized report indicated they would be most interested in a broad analysis akin to the old annual reports. Given the MCSO’s need for the broadly scoped analysis as opposed to a topically-focused and interpretive report, the report here primarily provides analyses across most of the core instrument elements, presented in tabular form, with a list of key findings and highlights.

The Arizona Arrestee Reporting Information Network is a drug abuse monitoring system that provides on-going descriptive information about drug use, crime, victimization, and other characteristics of interest among individuals arrested in Maricopa County, Arizona. In five facilities throughout the county, professionally trained interviewers conduct voluntary and confidential interviews with recently booked arrestees. Questions focus on a range of topics including demographics, patterns of drug use (lifetime and recent), criminal activity, gang affiliation, victimization, mental health, citizenship, and treatment experiences. Each interviewee also provides a urine specimen that is tested for the presence of alcohol and/or drugs.

Over the past several years, Arizona policymakers have debated a number of immigration-related crime control policies. These discussions have ranged from arguments over the wisdom of granting local law enforcement agencies the authority to arrest and prosecute illegal aliens, to enacting legislation that sanctions employers for hiring illegal aliens. The perception that illegal aliens are responsible for a disproportionate amount of crime and violence in the state is at the root of many of these policy discussions. This report examines the connection between illegal aliens and crime in Maricopa County, Arizona, using data from the Arizona Arrestee Reporting Information Network.
