Measuring disparities in police use of force and injury among persons with serious mental illness.

Objectives: To measure disparities in experience of police use of force and injury among persons with serious mental illnesses.

Methods: We gathered novel police use of force and suspect injury data from 2011 to 2017 from a nonrandom sample of nine police departments in the United States and used synthetic methods to estimate the share of the local population with serious mental illness. We estimate disparities using multi-level models estimated in a Bayesian framework.
