Former Officer Derek Chauvin was justified in pinning George Floyd to the ground because of his frantic resistance, a use-of-force expert testified for the defense Tuesday, contradicting a parade of authorities from both inside and outside the Minneapolis Police Department. Taking the stand at Chauvin's murder trial, Barry Brodd, a former Santa Rosa, California, police officer, said officers don't have to wait for something bad to happen; they need only to have a reasonable fear that there's a threat and then adjust their actions accordingly. "It's easy to sit and judge ... an officer's conduct. It's more of a challenge to, again, put yourself in the officer's shoes to try to make an evaluation through what they're feeling, what they're sensing, the fear they have, and then make a determination," Brodd said. He also said he didn't believe Chauvin and the other officers used deadly force when they pinned Floyd on his stomach, with his hands cuffed behind his back and Chauvin's knee on his neck or neck area for what prosecutors say was 9 1/2 minutes. Brodd likened it to a situation in which officers used a Taser on someone fighting with officers, and the suspect fell, hit his head and died. Chauvin attorney Eric Nelson is has argued that the now-fired white officer did what he was trained to do and that Floyd died because of his illegal drug use and underlying heart condition, not because of Chauvin pinning him to the pavement last May.
