Chauvin use of force on Floyd 'totally unnecessary': senior officer

Police officer Derek Chauvin's use of force against George Floyd was "totally unnecessary," the longest-serving officer in the Minneapolis Police Department testified on Friday.

Lieutenant Richard Zimmerman, giving evidence for the prosecution on the fifth day of Chauvin's murder and manslaughter trial, said the sacked 19-year veteran officer had violated department policies on the use of force.

Zimmerman told prosecutor Matthew Frank that he had reviewed bystander video and police bodycam footage of Floyd's May 25, 2020 arrest by Chauvin and three other officers who are also facing charges.

Asked by Frank what he thought about Chauvin's use of force against Floyd, Zimmerman said: "Totally unnecessary."

"Pulling him down to the ground facedown and putting your knee on a neck for that amount of time, it's just uncalled for," he said.

"I saw no reason why the officers felt they were in danger -- if that's what they felt, and that's what they would have to feel -- to use that kind of force," he said.

Video shows Chauvin, who is white, kneeling on the neck of a handcuffed Floyd for more than nine minutes following the arrest of the 46-year-old Black man for passing a counterfeit fake $20 bill.

Floyd's death sparked protests against racial injustice and police brutality across the United States and around the world.

Prosecutors are seeking to prove that Chauvin's actions led to the death of Floyd, who was lying on his stomach, facedown in the street saying repeatedly: "I can't breathe."

Eric Nelson, the former officer's defense attorney, claims Floyd died due to illegal drug use and underlying medical conditions.

'His safety is your responsibility'

A paramedic testified on Thursday that Floyd was already dead when he arrived on the scene in an ambulance and that Chauvin was still kneeling on his neck when he showed up.

Zimmerman, who joined the Minneapolis Police Department in 1985 and is currently with the homicide unit, was asked by Frank if he had been "trained to kneel on the neck of someone who is handcuffed behind their back in the prone position?"

"No I haven't," he said.

Once a suspect is handcuffed "that person is yours," he said. "He's your responsibility. His safety is your responsibility."

"Once a person is cuffed, the threat level goes down, all the way," he said. "They're cuffed. How can they really hurt you?"

Zimmerman also said that once a suspect is in handcuffs "you need to get them out of the prone position as soon as possible because it restricts their breathing."

"You need to turn them on their side or have them sit up," he said.

Zimmerman's testimony came one day after that of the police sergeant who had been Chauvin's shift supervisor on the day of Floyd's arrest.

David Pleoger, who has since retired, was asked by prosecutors to give his opinion about the use of force in Floyd's arrest.

"When Mr. Floyd was no longer offering up any resistance to the officers they could have ended their restraint," Pleoger said.

Derek Smith, a paramedic, testified on Thursday that Chauvin and other police officers were still on top of Floyd when he and fellow paramedic Seth Bravinder arrived on the scene.

Smith said he checked the carotid artery in Floyd's neck to see if he had a pulse. "I did not feel one," he said. "In lay terms, I thought he was dead."

Smith said Floyd was loaded into the ambulance and they tried to revive him using chest compressions and a defibrillator.

Their efforts were unsuccessful.

Besides hearing from police officers and witnesses, the nine-woman, five-man jury hearing the case in a heavily guarded Minneapolis courtroom has been shown bystander video and police bodycam footage of Floyd's arrest.

Chauvin, who has been free on bail, faces up to 40 years in prison if convicted of the most serious charge -- second-degree murder.

The other three former police officers involved in the arrest -- Tou Thao, Thomas Lane, and J. Alexander Kueng -- are to be tried separately later this year.
