MINNEAPOLIS – An expert witness told jurors in the murder trial of former Minneapolis cop Derek Chauvin on Wednesday that Chauvin used “lethal” force on George Floyd and kept his knee on Floyd’s neck for more than nine minutes.
Sgt. Jody Stiger, an officer with the Los Angeles Police Department who conducted around 2,500 use of force reviews during his career, said the initial force used on Floyd was appropriate because Floyd resisted arrest as officers attempted to get him into their patrol car.
However, after the officers forced Floyd to the ground, “they should have defused the situation,” Stiger said. Instead, the officers continued to escalate the situation, he said.
Meanwhile, Rodney Floyd said on Tuesday that his brother’s last words from the videos shown time and again in the courtroom replaced his memory of their last conversation, in which they remembered their late mother. “When someone dies you cherish their last words, but my brother’s last words, oh those words are stuck in my head. Dying,” he told reporters.
Chauvin, who is white, is charged with second degree murder, third degree murder and second degree manslaughter in the death of Floyd, a black man who died in police custody on May 25, 2020.
Where is the trial taking place: Prosecutors, on their eighth day, switched from giving eyewitness testimony to focusing on Chauvin’s use of force, trying to show that Chauvin’s restraint was excessive and led to Floyd’s death. The defense drew testimony suggesting that the officers were threatened and distracted by an unruly crowd, faced initial resistance from Floyd, and decided not to use a “hobbled” restraint that would have tied his legs to his arms. The defense argued that Floyd died from the drugs in his system and from underlying medical issues.

Expert witness Sgt. Jody Stiger says Chauvin’s use of force was ‘excessive’
Sgt. Jody Stiger of the Los Angeles Police Department returned to the witness stand Wednesday morning. Stiger trained around 6,000 officers on de-escalation, basic patrol tactics and other topics
Stiger told jurors on Tuesday that after reviewing the case, he determined that Chauvin’s use of force was “excessive.” He said he uses the “objectively reasonable” standard established in the 1989 United States Supreme Court case, Graham v. Connor. This legal standard takes into account the seriousness of a crime, whether someone poses an immediate threat to the safety of others, and whether someone actively resists arrest or attempts to flee.
Regarding the seriousness of Floyd’s crime, Stiger said that, given the alleged offense – trying to pass a fake $ 20 bill – “you wouldn’t even expect to use force of any kind. ” In assessing whether Floyd posed a threat to the safety of others, he stated that a subject’s size and stature may be relevant, but that it is not appropriate to use force against someone simply. due to its larger size.

On Wednesday, Stiger testified that, based on the time stamps from the police corps cameras, the pressure Chauvin put on Floyd lasted nine minutes and 29 seconds and that Chauvin kept the knee pressure on Floyd’s neck for the entire duration of the restraint.
Stiger said the number of officers at the scene outweighed any threat posed by Floyd, who was not actively resisting while in the prone position. He said “that no force should have been used after being in this position.” But the pressure exerted by Chauvin “raised the possibility of death,” he said.
Stiger said video evidence from the crowd watching officers subdue Floyd showed passers-by shouting but not threatening officers. He said audio streams of videos from the scene showed Chauvin did not appear to have been distracted by spectators. “You can hear Mr. Floyd show his discomfort and pain, and you can hear the accused respond to him,” Stiger said.He added that Chauvin had had 866 hours of paid training during his 19 years in the force, which should have been enough for him to cope with a crowd distraction.
On cross-examination by lead defense counsel Eric Nelson, Stiger admitted that he had never before testified in court as an expert on the use of force by police. He also acknowledged that the policies of different police services may be “to some extent different”. However, he testified that all departments must adhere to the Graham v. Connor “objectively reasonable”.
Using references to Minneapolis Police radio transmissions, Nelson convinced Stiger that Chauvin had reason to believe by going to the scene that Floyd was 6 to 6 1/2 feet tall and apparently impaired by drugs or l ‘alcohol. When Chauvin arrived and saw Floyd resist the efforts of other officers to get him into the back of a patrol car, it would have been reasonable for Chauvin to use a Taser on Floyd, Stiger agreed.
EMT Nicole Mackenzie: Officers should call an ambulance and provide assistance if the situation is ‘critical’
Minneapolis Police Department officer Nicole Mackenzie, a paramedic and the department’s medical support coordinator, told jurors officers are required to provide medical assistance and call an ambulance if the situation is “critical”.
Mackenzie said officers receive CPR training every two years. Prosecutor Steve Schleicher displayed the CPR cards issued to Chauvin to show he had the necessary training.
Mackenzie said ministry policy requires officers to check the pulse and give and continue CPR until an older person is on the scene with advanced training, there are obvious signs death or until the officer is completely exhausted.

Asked by District Attorney Steve Schleicher whether someone who speaks is still able to breathe, Mackenzie said, “Just because they talk doesn’t mean they breathe properly.”
In cross-examination by defense attorney Eric Nelson, MacKenzie acknowledged that certain situations can prevent an officer from calling EMS. Her testimony was cut short as the defense said it planned to call her back, as early as next Tuesday, in their case.
Sgt. Johnny Mercil, use of force instructor: officers failed to learn to put their knees on their necks
Minneapolis Police Lt. Johnny Mercil, who leads the use of force training division classes and taught at a class Derek Chauvin attended in October 2018, told jurors on Tuesday that a still image of Chauvin kneeling on Floyd’s neck is not a restraint taught to Minneapolis Police Department officers.
Mercil said using a knee on the neck or back may be a permitted use of force, but is generally transient and depends on the time frame and type of resistance. If the subject is handcuffed and does not resist, it is not allowed, Mercil said.

“There is the possibility and the risk that some people will have trouble breathing when they are handcuffed (on the back) and on their stomach,” Mercil said. One person is rolled onto their side to avoid positional asphyxiation, Mercil said. The officer should refer the person to this position “the sooner the better”, although he noted that this depends on the situation and the environment.
Asked by Chauvin’s lawyer Eric Nelson, Mercil admitted that use of force techniques do not have a strict application in all cases and that officers learn to be fluid and react to the circumstances they face. . Mercil also agreed under questioning that some people are making excuses to avoid being arrested, and that he had suspects say “I can’t breathe” as he tried to stop them. Read more.
