The document summarizes issues with past research on police use of force and proposes a new framework. It outlines two main problems with previous research: a lack of foundational evidence due to non-cooperation from police departments, and a lack of proper measurements in data collection. This led to inconsistent results and policies. The document then proposes a new "authority maintenance theory" framework based on social expectations in police-citizen encounters. This theory could provide structure for future research to better understand the causes of police use of force and help develop more effective policies.
