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.

The Maricopa County Public Defender’s Office provides tremendous value to the community by serving an important public safety function. We seek effective dispositions for addressing the underlying problems that contribute to our clients' criminal behavior, thus providing them with their best chance to become productive and law-abiding individuals. Its mission is to provide quality legal representation to indigent individuals assigned to us by the court, thus safeguarding the fundamental legal rights of each member of the community.

The purpose of this report is to use data from a sample of recently booked arrestees in Maricopa County to examine the scope and nature of Maricopa County’s gang problem. In particular, this report supplements data presented in the bi-annual report on gangs conducted by the Arizona Criminal Justice Commission, which relies on official police data and their occasional white paper on gangs that relies on self-report data from school youth. We organized our analyses around six research questions: (1) what proportion of adult arrestees are involved in a gang, and what are the socio-demographic differences between those who are associated with a gang and those who are not; (2) what are the rituals associated with gang joining; (3) how do gang and non-gang arrestees differ in their experiences with crime, drug use and victimization; (4) what is the organizational structure and composition of gangs; (5) how do members socially identify with their gang; and (6) how and why do members leave their gang?

This report seeks to address the knowledge gap in understanding the relationship between combat-related conditions such as PTSD and TBI and involvement in the criminal justice system, through an examination of 1,370 recently booked arrestees in Maricopa County, Arizona. Using interview data from the Arizona Arrestee Reporting Information Network (AARIN), the report characterizes the problems and prior experiences of military veterans, and compares veteran and nonveteran arrestees along a range of demographic, background and criminal behavior measures. The overall objectives of the report are to provide an ongoing estimate of the prevalence of military veterans in the Maricopa County arrestee population and to assess the extent to which the arrested veterans differ from the larger arrestee population.

In early 2009, an Exploratory Committee was formed to investigate the potential creation of a Veterans Court in Maricopa County, Arizona. The Committee’s initial efforts have focused on examining existing Veterans Courts and determining the size and scope of the problem (i.e., the number of veterans in the county jail). This report provides an overview of information on veterans in the Maricopa County Jail System, drawing on data collected by the Arizona Arrestee Reporting Information Network (AARIN). This report is intended to assist the work of the Veterans Court Exploratory Committee.

For the 2008 AARIN study, 2,105 Maricopa County (AZ) arrestees volunteered to complete the survey instrument and to provide a valid urine specimen for testing. In addition, the arrestees responded to a series of questions related to methamphetamine use, including patterns of use, treatment, drug transactions, sales and manufacturing, and awareness of the Arizona Meth Project. Among those participants, 435 (20.7%) admitted to having used methamphetamine in the 30 days prior to arrest.

The purpose of this report is to examine methamphetamine use among adult arrestees and juvenile detainees in Maricopa County, Arizona. We relied on data from the Arizona Arrestee Reporting Information Network (AARIN) to address the following five questions:
1. What percent of adult arrestees are methamphetamine users and what are their social characteristics?
2. What is the relationship between methamphetamine use and arresting offense?
3. What is the relationship between methamphetamine use by parents and the presence of children in the household?
4. What percent of methamphetamine users are receiving treatment for their drug use?
5. What percent of juvenile detainees are methamphetamine users and what are their social and legal characteristics?

During 2008, 2,105 adult arrestees participated in the AARIN study. Participants completed the survey instrument and provided a valid urine specimen for testing. In addition to the core AARIN instrument, a supplemental set of question was asked of the arrestees. This Market and Use Addendum consisted of a series of questions related to the arrestees’ acquisition of drugs and specific drug market behaviors.
