Overview

Analysis of fatal police shootings using regression methods reveals data discrepancies across agencies, indicating regional variation.

Key Points

  • Discrepancies in open-source data emerged, particularly for larger police agencies and state police, pointing to accuracy concerns.
  • Annual open-source counts diverged from self-reports for 5%-9% of agencies, highlighting variability by year and source.
  • Comparative analysis utilized regression methods and examined factors influencing overcounts in media reports.
  • Coordination among police agencies and data compilers may enhance the accuracy of fatal police shooting records.
