Now, Judge Cahill is walking the jurors through each of the charges.
Derek Chauvin is charged with second-degree unintentional murder, third-degree murder and second-degree manslaughter.
For each of the charges, all of the elements involved must be proved beyond a reasonable doubt for Chauvin to be convicted, Judge Cahill tells the jury.
"When he was unable to speak, the defendant continued, when he was unable to breathe, he continued...this assault for 9 minutes and 29 seconds," Schleicher said.
"The defendant had to know what was right beneath him. You saw the video...he was completely limp."
"The defendant was on top of him for 9 minutes and 29 seconds, and he had to know...he had to know."
"Our expectation is that the police are going to help...To be clear, this case is called the State of Minnesota vs. Derek Chauvin, not the State of Minnesota vs. police... Policing in a noble profession."
Speaking on Derek Chauvin's body language, Schleicher says that he was "not going to be told what to do...the bystanders were powerless. The defendant, he chose pride over policing."
"#GeorgeFloyd is not on trial...he didn't get a trial when he was alive."
Schleicher says that #GeorgeFloyd saw the back of the squad car and must have thought it seemed like a "cage" and "couldn't bring himself to get in.
He notes that police are trained to deal with this. "Officers wouldn't listen to him, or look at the signs."
Prosecutors show body-worn camera footage of #GeorgeFloyd's arrest.
Schleicher says that Floyd looked like he saw a monster when he saw the back of the squad car.
When officers pulled Floyd out of the car, he thanked the officers, Schleicher notes.
"They pushed him down to the ground...for what?"
Schleicher says that when #GeorgeFloyd was first taken out of the car, he was in the recovery position. But then officers put him in the prone position, which is known to carry the risk of positional asphyxia.
"Use your common sense. Believe your eyes. What you saw, you saw."
Schleicher is now talking to the jury about the law and "proof beyond a reasonable doubt."
"George Floyd was not a threat, he never was. He wasn't resisting, he just wasn't able to comply...But the defendant stayed on top of him, grinding his knee into him...not a reasonable use of force."
Schleicher notes that Chauvin didn't follow MPD policy.
"Force must be reasonable at the time it starts, by the time it ends, and at all points in between."
Nelson: If a person has drugs in their system and that drug causes an overdose in the context of the police restraint, it's not the natural consequence of the restraint, it's the natural consequence of the deceased's actions.
Nelson is now running through the medical witnesses called by the state.
Nelson: I submit to you that the testimonies [of the state's medical witnesses], it flies in the absolute face of reason and common sense. It's astounding.
Before testimony began, Eric Nelson, the attorney for Derek Chauvin, noted that the state intends to call Andrew Baker, the Hennepin County medical examiner who performed the autopsy on #GeorgeFloyd, tomorrow.
First up today is Dr. Martin Tobin, a physician in pulmonary critical care.
He defined pulmonology as "the study of the lungs...of all diseases that effect the respiratory system."
He is being questioned by prosecutor Jerry Blackwell.
Nelson: Doesn't "saying things like 'you're a f***ing p****, you're a b****" convey a particular intent?
Stiger: "I wouldn't say intent," adding it depends on the officer's training. | cbsloc.al/2PziOKt
Nelson calls up surveillance photo outside Cup Foods. Asks Stiger about Chauvin's position, and could that indicate less of his weight on his left side, where his knee is holding down Floyd. Stiger affirms.
Prosecution's Steven Schleicher begins redirect of witness Jody Stiger by asking about the risks of positional asphyxia, making a distinction between positioning as opposed to pressure and weight.
Day 8 of testimony in the #DerekChauvinTrial continues this morning with Sgt. Jody Stiger, a use-of-force expert from the Los Angeles Police Department.
Officer Stiger has been with the LAPD since 1993, and has worked with homicide and gang units. Has extensive experience with use of force reviews.
Officer Stiger, the state's expert witness, has reviewed all body cam footage, other videos including cell phone videos, reports, manuals from MPD, and training materials in his review of the May 25 incident.
