Transcript for Officers involved in arresting George Floyd were fired and could still face charges
It was sadly a night of rage across much of America. The epicenter of the protests, of course, Minneapolis, the city where George Floyd died after nearly nine minutes with his neck under the knee of a police officer. And both Minneapolis and neighboring St. Paul declared curfews but demonstrators defied those orders and police officers say shots were fired at them. The governor says he understands the outrage, but overnight he told the protesters, you need to go home. The protest came despite the fact that former officer Derek chauvin was arrested and charged with third degree murder. The anger in the streets spreading to at least 20 cities across the country from los Angeles to Denver to New York City and many more. The common refrain, "I can't breathe." The words Floyd said over and over before he died. Now, we will get reaction to all of that from Floyd family attorney Lee Merritt. But first we have team coverage including the latest on the investigation into the other officers who were on the scene when Floyd was begging for mercy. Let's start with ABC's Alex Perez in Minneapolis. Alex, good morning to you. Reporter: Tough morning here, whit. I want you to take a look behind me here. There are scenes like this one across this city, buildings completely destroyed, still smoldering. The Pentagon is readying the army, several units to be deployed if needed. The unrest is growing. Overnight outrage in the cities across the country over the death of George Floyd while in police custody. In Minneapolis, protesters out in the streets for another night despite a mandatory curfew. State officials saying they just don't have the resources to contain the protesters. The situation is incredibly dangerous. This is life-threatening. I'm deeply concerned with the people who -- you need to go home. Reporter: Overnight in Portland rioters breaking the windows of this capital one bank forcing their way inside while others set fires in the streets. In Atlanta chaos in the streets. One car set on fire. A tense standoff between protesters and police at CNN headquarters. Fireworks thrown at officers inside the building captured live on air. In New York, officers coming to blows with protesters outside the Barclay center. At least 150 people arrested. Protesters burning a blue lives matter flag on a burnt out NYPD van. In Los Angeles, demonstrators flooding the highway bringing traffic to a halt. And in Oakland, several officers injured from objects thrown by protesters there. Some setting a fire on a downtown street. The fourth day of demonstrations come after Derek chauvin, the white former Minneapolis police officer at the center of the firestorm, was arrested. His mug shot released overnight and charged with third degree murder of George Floyd. Please, please, I can't breathe. Please, man. Please, somebody help me. Reporter: That difficult to watch video showing chauvin jamming his knee into Floyd's neck while Floyd is handcuffed, pinning him on the ground. The horrified crowd begging him to stop. According to prosecutors the defendant had his knee on Mr. Floyd's neck for 8 minutes and 46 seconds in total. Two minutes and 53 seconds of this was after Mr. Floyd was nonresponsive. Police are trained that this type of restraint with a subject in a prone position is inherently dangerous. Police initially said Floyd resisted officers and noted he appeared to be suffering medical distress. He has been charged with third degree murder. We are in the process of continuing to review the evidence. There may be subsequent charges later. Reporter: Three other officers involved in arresting flood tau Thao, Thomas lane and Alexander kueng involved in arresting Floyd were also fired and could still face charges. New video shows lane and keung also pinning down Floyd as he pleads for his life while handcuffed. I'm not going to speculate today on the other officers. They are under investigation. I anticipate charges but I'm not going to get into that. Reporter: Now based on the charges, the officer who had his knee on Floyd's neck could face up to 35 years in prison. His wife says she's devastated by Floyd's death and has filed for a divorce.
