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.

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.
