STATISTICAL ANALYSIS OF I-17 VIOLATOR STUDY
STATISTICAL ANALYSIS OF I-40 STOP DATA


INTRODUCTION

     I make this report in response to the request of Counsel for Yavapai County defendants stopped and arrested by Arizona Department of Public Safety Officers, to determine whether there is a colorable basis for asserting that minority motorists are being targeted by the police for traffic stops and searches.

     To determine whether a colorable claim of racial profiling (the disproportionate targeting of motorists to be stopped by DPS officers on I-17 in Yavapai County by race and ethnicity) exists, two pieces of information are required. The first piece of information is the racial and ethnic composition of all known motorists stopped and ultimately charged with drug-related offenses on I-17 in Yavapai County from 2000 through 2002. This information is best found in a comprehensive review of criminal case defendants in Yavapai County stopped on I-17 and charged with drug-related offenses from 2000 through 2002. Results of this review then need to be compared to a base figure of the racial and ethnic composition of people traveling on I-17 in Yavapai County who are violating motor vehicle laws and thus eligible to be stopped by DPS Officers. If the racial and ethnic composition of known defendants is similar to the racial and ethnic composition of motor vehicle law violators, a colorable claim of racial profiling cannot be said to exist. If the comparison yields significant disparity between the race/ethnicity of known defendants and motor vehicle law violators, a colorable claim of racial profiling can be said to exist. Significant disparity will be shown to exist if differences between the two populations exceed the margin of error associated with the violator study data.

KNOWN STOPS ON I-17

     Anita Pitroff, Yavapai County Public Defenders Office Paralegal, conducted a review of known drug cases from I-17 within the boundaries of Yavapai County from 2000 through 2002. Her report indicates the Yavapai County Public Defenders records were searched for known cases. In-house and contract attorneys reviewed more than 2,700 drug cases known to the Public Defenders office and determined that 32 defendants are known to have been involved in I-17 drug cases from 2000 through 2002. Of the 32 defendants, 17 (53.1%) were African American, 4 (11.8%) were Hispanic, and 11 (34.4%) were non-Hispanic, Caucasians (see Table 1).

     The Public Defender’s Office tracks all of its cases through a database system. Every criminal case in Yavapai County in which a defendant is appointed an attorney by the court is recorded in the database system. Tracked fields include the Defendant’s name, case number, attorney assigned (whether in-house, contract or private), date opened, charges filed, and whether or not the charges are drug-related. The drug-related field is kept to satisfy a grant requirement. The database can be searched by fields and filters can be used to screen in or out selected criteria.

     To identify the drug-related cases in Yavapai County, the database was searched by drug-related field and date opened, identifying 2,700 drug-related cases opened between 2000 and 2002. This database was further screened by attorney assigned, generating separate lists of drug-related cases opened between 2000 and 2002 by attorney. Each attorney identified was given his or her individual list of cases and asked to identify cases on the list which were I-17 stops and the race of the defendant and any passengers or co-defendants. Attorneys reported this information back to the Public Defender’s Office either by returning the list with handwritten notes, or calling the Public Defender’s Office and giving a report orally. As several new cases arose after the lists went out, attorneys called the Public Defender’s Office to report new cases.
