Chicago saw widespread looting following Floyd's death last May.
Minneapolis and other USA cities were ramping up security measures on Monday, girding for possible protests after a jury delivers a verdict in the trial of former Minneapolis police officer Derek Chauvin, charged with murdering George Floyd by kneeling on his neck. Deliberations took less than one day.
During the prosecution's argument, Schleicher replayed portions of the bystander video and other footage as he dismissed certain defence theories about Floyd's death as "nonsense".
Chauvin was captured on video kneeling on the neck of Floyd as he was pinned facedown handcuffed on the ground for more than nine minutes complaining "I can't breathe".
Grand Rapids, which had some of Michigan's worst violence last May after Floyd's death, placed concrete barriers around the police department just hours before the verdict was announced.
Schleicher on Monday pointed to Chauvin's ego and refusal to take his knee off Floyd when onlookers yelled at him to do so as to why Floyd had died. He said of the video of Mr Floyd's arrest: "I don't think he had any intention of harming anybody, but somebody did die".
Nelson said he did not think the jury could be unaffected by media attention and singled out Waters: "Now that we have United States representatives threatening acts of violence in relation to this specific case, it's mind-boggling".
"He did not purposefully use unlawful force", Nelson said. The defense attorney spent most of his closing arguments defending Chauvin's use of force and behaviour, saying Chauvin had behaved as any "reasonable officer" would.
He said the prosecution's focus on 9 minutes and 29 seconds, rather than Floyd's active resistance in the minutes earlier, was inappropriate.
"Our goal is de-escalation and non confrontation at all chances", Walz told reporters.
On Tuesday, President Joe Biden said he was praying for the "right verdict" in the trial.
"It's overwhelming in my view", the president said of the outcome. If convicted, he faces up to 40 years in prison. The maximum sentence for second-degree manslaughter is 10 years and/or $20,000.
Chauvin will be remanded until sentencing.
Chauvin is facing three charges in the death of Floyd: second-degree unintentional murder, third-degree murder and second-degree manslaughter.
Trial judge Peter Cahill told the jury not to draw any inference on Chauvin's innocence or guilt from his declining to testify. Prosecutors fought hard to add a third-degree murder charge against Chauvin, but a conviction on that charge alone could set up a problematic scenario for them. Because Chauvin does not have a criminal record, he would avoid a maximum sentence of 25 years, according to the sentencing guidelines. Cahill then reinstated the charge against Chauvin. The state did not have to prove for this charge that Chauvin's actions meant to kill Floyd.
Before the deliberations last week, Cahill instructed the jurors to pack enough clothes for what has the potential to be a long process. "I'm anxious to see you guys, I really am". The jury is now deliberating. "And so because that's entirely up to you - whether it's an hour or a week - it's entirely within your province". "And so I waited until the jury was sequestered, and I called".
The jury returned to the courthouse this morning (local time) to resume their deliberations, having failed to reach a verdict on Monday.
"This wasn't policing, this was murder", he said.
Tensions are high as the jury begins deliberations, with National Guard troops deployed in Minneapolis after Daunte Wright, a 20-year-old Black man, was shot dead in a suburb of the Minnesota city on April 11 by a white policewoman. Noor is the only police officer to be convicted of murder for an on-duty killing in Minnesota - and Chauvin would be the second.

In a video circulating on Twitter that afternoon, three white officers allegedly taunted residents by saying "Blue Lives Matter". Police also are expected to release more body camera footage of the shooting on Wednesday, reports say.
