ABOUT THE SERIES
 
As part of an investigation into the effects of S.B. 1070, the Arizona Daily Star collected thousands of records documenting local police calls to Border Patrol to check a person’s immigration status. Although the intention of the legislation was to standardize local immigration enforcement, the end result was a patchwork of policies and interpretations that engrained philosophical differences across jurisdictions.This series examines in depth the practices of 13 Southern Arizona law-enforcement agencies and the economic and legislative impacts of the law.
