EXPLAINER: Why outside prosecutors review killings by police

BOSTON (AP) — A white former police officer is being charged with second-degree manslaughter in the killing of 20-year-old Daunte Wright, just three days after the Black man was shot during a traffic stop in a Minneapolis suburb. The swift probe and announcement of a charge against Kim Potter was handled by a prosecutor from outside Brooklyn Center, Minnesota, where Potter shot Wright. The decision to hand over the case was made almost immediately by Hennepin County Attorney Mike Freeman.
