Transcript for Jury deliberates Chauvin case in death of George Floyd
Good evening and it's great to have you with us as we start another week together here. A very busy start to the week tonight. And we begin this evening with the dramatic moments in court today. The prosecution and the defense, their final arguments in the trial of former Minneapolis police officer Derek chauvin. Tonight, it is now the jury's turn. They have been given instructions by the judge and from this point forward, they will be sequestered until there's a verdict. The prosecution starting by weaving a very personal native about George Floyd, reminding the jurors he had a family, he was loved, had a deep connection to his mother, who he called out for during those 9 minutes, 29 seconds, repeat Bly saying he could not breathe. The prosecutor saying this is not an anti-police prosecution, this is about officer Derek chauvin, who betrayed the badge, they said, and the police witnesses who testified about that betray. The prosecution telling the jurors what they told them in their opening statement weeks ago, that you can believe your eyes, that this is a homicide. The defense arguing that Derek chauvin acted reasonably, that he followed police guidelines. Chauvin taking off his mask so the jury could see him as his attorney defended him in the closing arguments. His lawyer asking jurors to consider what came before those nine minutes, the 16 minutes before and to consider other factors that could have played a role in George Floyd's death. The prosecution's rebuttal, saying our task is to show that Derek chauvin and his knee to Floyd's neck was a substantial cause of death, not the only cause, but a substantial one. Reminding the jurors of the 9-year-old girl who testified and what she said that day, witnessing it all, to get off him. Tonight, what comes next now. The jurors sequestered. And ABC's Alex Perez leads us off now from Minneapolis. Reporter: The prosecution's closing message to the jury was clear -- believe your own eyes. What you saw in the video of George Floyd's final moments was murder plain and simple. It's exactly what you believed. It's exactly what you saw with your eyes. It's exactly what you knew. It's what you felt in your gut. It's what you now know in your heart. This wasn't policing. This was murder. Reporter: Prosecutor Steve Schleicher arguing Floyd posed no threat to Derek chauvin. George Floyd was not a threat, he never was. He wasn't resisting. He just wasn't able to comply. They had him handcuffed. Reporter: He took on the defense notion that Floyd experienced a surge of strength in the struggle. There was no super human strength that day. Just a human, just a man. Lying on the pavement being pressed upon, desperately crying out. A grown man. Crying out for his mother, a human being. Reporter: The prosecutor arguing chauvin used excessive force, violating both the spirit and the letter of police department policy. George Floyd begged until he could speak no more and the defendant continued this assault. Reporter: Again and again he emphasized the police force it self is not on trial -- just one rogue officer. The defendant is on trial not for being a police officer, he's not on trial for who he was, he's on trial for what he did. Reporter: The prosecution's closing argument lasting about 1 hour and 45 minutes. The defense spending nearly three hours. Chauvin removing his mask so the jury could see his face as his attorney argued he acted as a reasonable police officer would. You have to take into account that officers are human beings, capable of making mistakes in highly stressful situations. Reporter: Eric Nelson telling the jury the bystander video of Floyd's final moment does not tell the whole story. A reasonable police officer would, in fact, take into consideration the previous 16 minutes and 59 seconds. Their experience with the subject, the struggle that they had. Reporter: He showed video of Floyd resisting in the squad car. Mr. Floyd was able to overcome the efforts of three police officers while handcuffed. Reporter: And he argued the bystanders seemed like a threat. A reasonable police officer is recognizing that the crowd is in crisis. So a reasonable police officer considers his department's training. What are these potential signs of aggression that I may be confronted with? Reporter: The defense also arguing drugs and heart disease led to Floyd's death. The failure of the state's experts to acknowledge any possibility, any possibility at all, that any of these other factors in any way contributed to Mr. Floyd's death defies medical science and it defies common sense and reason. Reporter: The prosecution challenging that point in rebuttal, arguing even if Floyd's drug use and heart condition contributed to Floyd's death, what matters is that Derek chauvin's actions caused his death. Prosecutor Jerry Blackwell recalling the testimony of the 9-year-old girl who took the witness stand. The fact that is so simple that a child could understand it. In fact, a child did understand it, when the 9-year-old girl said, "Get off of him." That's how simple it was. "Get off of him." Alex Perez joins us now from Minneapolis. And Alex, the case is now in the jury's hands tonight. The judge ininstructing them not to let bias, prejudice, passion, sympathy or public opinion influence their decision and warning them not to consider what consequences their verdict might have. These jurors likely know, though, the country is watching. Reporter: Yeah, David. The judge very slowly and carefully explaining all of those instructions to the jury. Beginning tonight, they will be sequestered during deliberations. They'll work each evening until about 7:30. They have been given laptops with all of that video and other evidence that they saw in court. David? Alex Perez leading us off from Minneapolis. Alex, thank you. I want to bring in Dan Abrams
