In April, former police officer Kim Potter killed Daunte Wright at a traffic stop.

She admitted to the killing, saying she mistook her gun for her taser.

The defense opened by emphasizing Potter’s training.

They also emphasized the differences between the taser and her gun.

They noted the stark color differences and the different weights of the two objects.

Wright’s mother, Katie Bryant, was in tears when she recalled the event.

She was on a call through Facebook Messenger with her son when he was pulled over.

She was still on the phone when she heard “sounds of a struggle.”

Potter is facing charges of first and second degree manslaughter.
