Officer Nicole Mackenzie, the Minneapolis Police Department’s medical support coordinator, told prosecutor Steve Schleicher that cardiopulmonary resuscitation (CPR) can be started while waiting for paramedics to arrive — a point the prosecution has sought to drive home to suggest Derek Chauvin had a duty to provide medical treatment to George Floyd until paramedics arrived.
The prosecution has called witnesses to the stand, including Minneapolis Police Chief Medaria Arradondo, who said that Chauvin had violated a range of departmental policies, including by not rendering aid to Floyd before the ambulance was at the scene. Floyd did not receive medical attention May 25 until two paramedics arrived.
As police officers were arresting Floyd, bystander videos captured him repeatedly telling them he couldn’t breathe. One officer can be heard telling Floyd that it takes “a lot of oxygen” to talk.
Mackenzie, who trains Minneapolis police officers in medical treatment, contradicted that statement Tuesday.
“There is a possibility somebody could be in respiratory distress and still be able to verbalize it,” she said. “Just because they’re speaking doesn’t mean they’re breathing adequately.”
In his questioning of Mackenzie, Chauvin’s attorney, Eric Nelson, continued a line of questions that he has asked many other expert witnesses and bystanders to Floyd’s arrest, suggesting that the onlookers at the scene — many of whom shouted at Chauvin to get off Floyd — influenced Chauvin’s actions that day and potentially hampered his ability to render aid.
Mackenzie told Nelson that it is “incredibly difficult” to focus on a patient at a chaotic scene and that it’s more difficult to assess a patient.
“Does it make it more likely that you might miss signs if a patient is experiencing something?” Nelson asked. Mackenzie said it was possible.
Schleicher quickly followed up and asked if a crowd of onlookers excuses a police officer from rendering aid.
“Only if they were physically getting themselves involved,” she said.

Los Angeles police sergeant testifies as use-of-force expert witness
The 26th witness in the Derek Chauvin murder trial is Sgt. Jody Stiger of the Los Angeles Police Department. He will testify as an outside expert on police training and use of force.
Stiger is an aide to the inspector general within the Los Angeles Police Department, which is an oversight entity. He said Tuesday afternoon he is the only sworn police officer that works for that unit.
He said he has also trained thousands of officers as part of a course he developed that went over de-escalation, firearms manipulation, basic control tactics and arrest-control techniques.

Minneapolis police use-of-force trainer testifies under cross-examination
Under cross-examination, Derek Chauvin’s attorney, Eric Nelson, entered a photo into evidence that Lt. Johnny Mercil agreed appeared to show Chauvin’s knee on George Floyd’s shoulder blade while the ambulance was on the scene.
Nelson asked Mercil, a use of force trainer with the Minneapolis Police Department, whether unconscious people can suddenly regain consciousness and fight and whether a restraint requires pressure on both sides of the neck for the person to go unconscious.
Mercil responded yes to both questions. Mercil also testified that it generally takes less than 10 seconds for someone to go unconscious because of a neck restraint.
With these questions, Nelson seems to be laying the groundwork that Floyd did not die from Chauvin’s knee on his neck, as the prosecution has argued.
On Monday, Nelson played a few seconds of bystander video side-by-side with footage from an officer’s body camera and asked Minneapolis Police Chief Medaria Arradondo whether Chauvin’s knee was on Floyd’s neck.
Arradondo agreed it appeared to show Chauvin’s knee on Floyd’s shoulder blade. But moments later, prosecutor Steve Schleicher got Arradondo to note that the clip played by Nelson depicted only the few seconds before Floyd was moved onto a stretcher and after paramedics had arrived.

Minneapolis Police Department use-of-force instructor said Chauvin’s knee restraint not part of training
A use-of-force instructor with the Minneapolis Police Department testified Tuesday that Chauvin’s use of his knee on George Floyd’s neck has never been a trained neck restraint in the department and would not be appropriate for a suspect that was “under control and handcuffed.”
Lt. Johnny Mercil said Tuesday morning while viewing an image of Chauvin restraining Floyd with his knee on Floyd’s neck that such an action is not and has never been taught as a neck restraint under department training.
He said, depending on the circumstances, such a tactic may not always be “unauthorized” but would not be an appropriate use of force in the case where a person was “under control and handcuffed.”
The lieutenant testified that in order to get a subject under control, officers are trained to “use the lowest level of force possible” in order to meet their objectives.
Prosecutors showed an image from the police department’s defense and control response training guide showing an “unconscious neck restraint,” meaning the kind of neck restraint that would render a person unconscious, would be allowed when a subject was displaying “active aggression” and not fall under tactics used for “active resistance” or “passive resistance.”
Mercil also testified officers are shown how to do an unconscious neck restraint with their arms but not using their legs during training.
The prosecution showed documents Chauvin had received training on the department’s use-of-force policies. Mercil developed the curriculum and was one of the trainers providing the use-of-force training Chauvin would have taken.
