St Paul, Minn. — Prosecutors in the trial of three former Minneapolis police officers charged with violating George Floyd’s civil rights accused the men Monday of standing by as fellow Officer Derek Chauvin “slowly killed George Floyd right in front of them.”

But one defense attorney countered that Chauvin called “all of the shots” as the senior officer at the scene, and criticized the Minneapolis Police Department for doing too little to train officers to intervene when a colleague should be stopped.

Former Officers J. Alexander Kueng, Thomas Lane and Tou Thao are broadly charged with depriving Floyd of his civil rights while acting under government authority. Floyd died on May 25, 2020, after Chauvin pressed him to the ground with his knee on Floyd’s neck for 9 1/2 minutes while the 46-year-old Black man was facedown, handcuffed and gasping for air. Kueng knelt on Floyd’s back and Lane held down his legs. Thao kept bystanders from intervening in the videotaped killing that triggered worldwide protests and a reexamination of racism and policing. Chauvin was convicted of murder and manslaughter in state court last year.

“For second after second, minute after minute, these three CPR-trained defendants stood or knelt next to Officer Chauvin as he slowly killed George Floyd right in front of them,” prosecutor Samantha Trepel, who works for the Justice Department’s civil rights division, told the jury during opening statements. “They chose not to protect George Floyd, the man they had handcuffed and placed in their custody.”

Tom Plunkett, the attorney for Kueng, highlighted the rookie status of his client and Lane, and said both men deferred to Chauvin and called him “sir.” "You’ll see and hear that officer Chauvin called all the shots."

“You’ll see and hear officer Chauvin call all of the shots,” said Plunkett, who also hammered at what he called the Minneapolis Police Department’s lack of training, including on intervention against the unreasonable use of force.

Plunkett noted that Chauvin was Kueng’s field training officer, and as such had “considerable sway” over his future. He also said that Kueng and Lane were not trained in the department’s policy on neck restraint.

He also said that under department policy, Lane actually should have been in charge, because he was the most senior officer in the first car to arrive on the scene. Lane and Kueng were responding to a 911 call accusing Floyd of using a counterfeit $20 bill for a pack of cigarettes at a corner market. Thao and Chauvin responded as backup. Earlier, Thao’s attorney, Robert Paule, said Floyd’s death was a tragedy, “however, a tragedy is not a crime.” He also said a widely watched bystander video of the arrest does not show everything that happened before, including Floyd struggling with officers who were trying to put him in a police vehicle.

Kueng, who is Black; Lane, who is white; and Thao, who is Hmong American, are all charged for failing to provide Floyd with medical care. Thao and Kueng face an additional count for failing to stop Chauvin, who is white. Both counts allege the officers’ actions resulted in Floyd’s death.

“We will ask you to hold these men accountable for choosing to do nothing and watch a man die,” Trepel said.

"These three CPR-trained defendants stood or knelt next to Officer Chauvin as he slowly killed George Floyd right in front of them."

Attorneys for both Kueng and Thao noted that prosecutors must prove Kueng, Lane and Thao willfully violated Floyd’s constitutional rights.

It’s a high legal standard; essentially, prosecutors must prove that the officers knew what they were doing was wrong, but did it anyway.

Trepel said videos will show Thao stood directly next to Chauvin, but instead of intervening, he taunted Floyd for using drugs, telling bystanders, “This is why you don’t” use drugs. She said Kueng “never once” told Chauvin to get off Floyd, even after Floyd stopped struggling and Kueng twice could not find a pulse. Instead, she said, Keung remained kneeling on Floyd.

Plunkett said Kueng told Chauvin that he could not detect a pulse — and told him he did not check the artery in Floyd’s neck because Chauvin was in the best position to do that.

Lane asked if they should roll Floyd onto his side — something all of the officers were trained to do — but Kueng shot down Lane’s question and said, “No, just leave him,” and Chauvin agreed, Trepel said.

Last week, 18 people were swiftly chosen for the jury; 12 will deliberate and six will be alternates. Two of the jurors — one expected to deliberate and one alternate — appear to be of Asian descent. The rest appear to be white. The court declined to provide demographic information.

U.S. District Judge Paul Magnuson told jurors that the trial could last four weeks. It’s not known whether any of the three officers will testify. It’s also not clear whether Chauvin will testify, though many experts who spoke to The Associated Press believe he won’t.

Lane, Kueng and Thao also face a separate state trial in June on charges they aided and abetted both murder and manslaughter.
