A Minneapolis medical support coordinator who trained two of three former officers federally charged in George Floyd’s death testified on Tuesday that what she saw of the officers’ actions was “inconsistent” with their training. In testimony the Associated Press covered, prosecutor Allan Slaughter asked Officer Nicole Mackenzie specifically about a portion of body camera video that showed Floyd repeatedly saying, “I can’t breathe,” while former cop Derek Chauvin kneeled on Floyd’s neck for more than nine minutes.

Thomas Lane and J. Alexander Kueng held Floyd down, and Tou Thao blocked bystanders from providing aid to the Black father. Mackenzie said in her second day of testimony that when Floyd repeatedly said he couldn’t breathe, Kueng and Lane should have sat him up or rolled him on his side. She said Thao offered no aid from what she could see.

Kueng, Thao, and Lane are accused of violating Floyd’s civil rights. Thao and Kueng pleaded not guilty to failing to intervene in Chauvin’s use of unreasonable force, and Lane, Thao, and Kueng pleaded not guilty to willfully failing to aid Floyd. Chauvin was convicted of murder and sentenced to 22.5 years in prison in the state case against him. He pleaded guilty to federal charges against him in a plea deal that caps any additional time in prison at two and a half years.

According to the Associated Press, it was established in court that Floyd was unresponsive and officers couldn’t find a pulse, but that Chauvin, the longest-serving officer on the scene, had instructed his peers to wait for an ambulance while the officers continued restraining Floyd. Mackenzie testified that “as long as I’ve been around,” the standard has been to begin CPR.

“If you can’t detect a pulse after about 10 seconds, then you should begin CPR,” Mackenzie testified.

Defense attorneys zeroed in on a suggestion the defense raised repeatedly in the state trial with Chauvin, and that is the notion that Floyd was in a state of excited delirium. The National Institutes of Health wrote in its research of the condition that it is typically associated with drug use and puts the victim in danger of suffering cardiopulmonary arrest.

Experts have testified that Floyd didn’t appear to be experiencing excited delirium, but Robert Paule, Thao’s attorney, raised the suggestion, the Associated Press reported. He pointed to a training video that showed a cadet with his knee on someone’s neck and a photo Thao was shown during training that showed an officer using his knee to detain someone believed to be experiencing excited delirium. Thomas Plunkett, Kueng’s attorney, said the photo was “problematic to say the least.”

Earl Gray, Lane’s attorney, seemed to make the most compelling case for his client, drawing attention to Lane’s efforts to perform chest compressions on Floyd and to convince Chauvin to roll Floyd on his side. According to the Associated Press, Gray said that Lane was the first to call an ambulance and that he told the ambulance service to “upgrade the call to lights-and-sirens” as Floyd’s condition worsened.

“He did pretty much everything he was trained to do at the school, correct?” Gray asked Mackenzie. She responded: “To a certain degree, yes.”

The prosecution, however, brought to light a major flaw in Lane’s actions with the question of why what he did wasn’t enough.

“Suggesting aid and actually rendering aid are two very different things,” Mackenzie said.

Ben Crump, the noted civil rights attorney who represented Floyd’s family, made the point on the news program Democracy Now that this case is about holding accountable the “culture of policing.” Journalist Amy Goodman had brought up an observation that Lane and Kueng had only been cops for a few days when they encountered Floyd.

“Oftentimes they say […] ‘This is one bad apple. They’re the good cops,’” Crump said in response. “Well, the good cops have to speak up when they see the bad cops violating the constitutional rights of minorities and [killing] us.”
