Police trainer testifies against officers in Floyd's death

A Minneapolis police officer who oversaw medical training for two of the three former officers charged with violating George Floyd's civil rights testified Tuesday that the officers were taught to give CPR as soon as they fail to find a pulse on someone.

Officer Nicole Mackenzie, the department's medical support coordinator, took the stand for a second day in the federal trial of J. Alexander Kueng, Thomas Lane and Tou Thao. She testified Monday that Kueng and Lane were in a police academy “emergency medical responder” class that she taught, which covered first aid, ethics in care and how to hand people off to paramedics. On Tuesday, Mackenzie also discussed refresher training that Thao would have received.

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

Kueng, Lane and Thao are accused of depriving Floyd, 46, of his rights when they failed to give him medical aid as Officer Derek Chauvin knelt on the Black man's neck for 91/2 minutes in May 2020 as Floyd was handcuffed, facedown. Kueng and Thao are also accused of failing to intervene in the killing, which triggered protests worldwide and a reexamination of racism and policing.

A lung specialist testified Monday that Floyd could have been saved if the officers had moved him into a position in which he could breathe more easily, and that his chances of survival would have “doubled or tripled” if they had performed CPR as soon as his heart stopped.

Previous testimony has established that Chauvin told his fellow officers after Floyd became unresponsive and they couldn't find a pulse to wait for an ambulance that was on its way. Officers kept restraining Floyd until the ambulance got there, according to testimony and video footage.

Mackenzie testified Tuesday that it's been the standard “as long as I've been around” that officers are supposed to call for an ambulance and begin CPR right away if they can't find a pulse. She said they're told not to wait even if an ambulance is already on the way.

Slaughter played body camera video in which Floyd repeatedly complains, “I can't breathe.” Mackenzie said what she saw and heard was “inconsistent” with what Kueng and Lane were trained to do and with departmental policies. She said they should have stood or sat Floyd up or rolled him onto his side.

Mackenzie also said what she saw and heard of Thao's actions when reviewing his body camera video was “inconsistent” with officers' training because she saw no efforts to render aid.

Defense attorneys contend the officers received inadequate training and have challenged statements by officials that Minneapolis officers are not trained to use their knees to pin people down the way Chauvin did.

Thao's attorney, Robert Paule, also has suggested that the officers were concerned that Floyd was in an agitated state known as excited delirium.
