Police departments around the United States are preparing for further protests as lawyers present their closing arguments in the trial of former Minneapolis policeman Derek Chauvin, accused of the murder of George Floyd.
Mr Floyd’s death in May last year during his arrest by Chauvin sparked the global “Black Lives Matter” protests.
In Minneapolis, plans are in place to clear government buildings in advance of the verdict, and the tower in which the courtroom sits is ringed by barbed wire, high barriers and armed soldiers from the National Guard, and nearby businesses have boarded up their windows.
Giant drab-coloured military vehicles have become a common sight in city streets.
The New York Police Department said it was also readying for possible citywide protests.
Nine minutes and 29 seconds
During the trial, over and over again, Steve Schleicher, a prosecutor with the Minnesota attorney general’s office, has repeated the phrase: “Nine minutes and 29 seconds,” – the length of time Mr Chauvin was captured on video kneeling on the dying Floyd’s neck.
Mr Schleicher emphasised that the jury was weighing the guilt of only one man, although their verdict will nonetheless be widely seen as a reckoning in the way the United States polices black people.
“This is not a prosecution of the police,” Mr Schleicher told jurors.
He cited the motto of the Minneapolis Police Department, which fired Mr Chauvin and three other officers involved the day after Mr Floyd’s arrest: “To protect with courage and to serve with compassion.”
Mr Chauvin, who is white, pushed his knee into the neck of Mr Floyd, a 46-year-old handcuffed black man, outside the grocery store that had accused Mr Floyd of using a counterfeit US$20 banknote to buy cigarettes.
No compassion shown, lawyer says
“George Floyd was not a threat to anyone,” Mr Schleicher said.
“Facing George Floyd that day that did not require one ounce of courage, and none was shown on that day, no courage was required. All that was required was a little compassion and none was shown on that day.”
“He was trapped with the unyielding pavement beneath him, as unyielding as the men who held him down,” Mr Schleicher said before playing some of the extensive video of Floyd’s death.
“What the defendant did not was not policing. What the defendant did was assault.”
Mr Chauvin has pleaded not guilty to second-degree unintentional murder, third-degree “depraved mind” murder and second-degree manslaughter.
He waived his right to testify before the jurors and his lead lawyer, Eric Nelson, was due to present his own closing argument later on Monday.
Chauvin says he was following his training
Mr Chauvin’s lawyers argued that he correctly followed the training he received over 19 years with the Minneapolis Police Department and sought to raise doubts about the cause of Floyd’s death.
For the second-degree murder charge, 12 jurors will have to agree that prosecutors proved beyond a reasonable doubt that Mr Chauvin committed a felony, in this case assault, that was a substantial cause in Mr Floyd’s death.
They do not have to find that the police officer intended to kill Mr Floyd.
That crime carries a punishment of up to 40 years in prison, although Minnesota sentencing guidelines call for a shorter sentence of up to 15 years for someone such as Mr Chauvin with no prior convictions.
Protests flare over latest deaths
US news networks carried live broadcasts of much of the testimony after the first of more than 40 witnesses took the stand three weeks ago, although the coverage was sometimes interrupted by fresh episodes of police violence caught on camera.
The closest instance occurred just a few kilometres from the courthouse in downtown Minneapolis when a white police officer fatally shot a black motorist, Daunte Wright, on April 11 in the suburb of Brooklyn Center after trying to arrest him on the belief he had missed a court appearance.
The officer, Kimberly Potter, had meant to use her Taser to stop him driving away but pulled out the wrong weapon, police say.
She has been charged with manslaughter.
