Several experts said with certainty that Chauvin’s neck restraint of Floyd was against guidance. “We tell officers to stay away from the neck when possible,” said Minneapolis Police Lt. Johnny Mercil, the use-of-force coordinator for the department. He called the restraint unauthorized and described it as “active aggression.”
Officer Nicole Mackenzie, the medical support coordinator for MPD, testified that officers like Chauvin who are trained in CPR learn that a subject’s ability to talk does not always mean they’re breathing properly. She also acknowledged under a line of questioning by defense lawyer Eric J. Nelson that distractions, like those from a surrounding crowd, can make it difficult to focus on lifesaving measures. The defense signaled it would bring her back to the stand when it starts its portion of the case.
