When a new district attorney takes office, police kill fewer people, according to a new study from Allison Stashko, an assistant professor in the Business Economics Group.

“Deaths decline no matter what the new prosecutor’s political party or policy platform might be,” Stashko writes. “During that time, we find no changes in arrest rates or assaults on police officers. That suggests that officers can de-escalate situations without either refraining from policing or risking greater harm themselves.”
