Outrage soared in America Friday over new images of police brutality caught on camera as demonstrators geared up for a second weekend of mass protests over the killing of an unarmed black man.
With rolling demonstrations over the death last week of George Floyd showing little sign of letting up, President Donald Trump sparked fresh controversy by saying strong jobs numbers marked a "great day" for Floyd.
Joe Biden, the presumptive Democratic nominee for November's election, called Trump's comments "frankly despicable," as thousands took to streets across America Friday for a 10th straight day of anti-racism demonstrations.
The protests, sparked by a police officer kneeling on Floyd's neck for almost nine minutes as he pleaded for his life, took place amid a roiling controversy over officers' us of force against largely peaceful protesters.
In Buffalo, New York, two policemen were suspended without pay after a video showed them shoving over a 75-year-old protester who fell and suffered a head injury.
Reporting the suspension on Twitter, city mayor Byron Brown said he and the police commissioner were "deeply disturbed" by the video.
An earlier police statement said the man, who appeared unconscious and bleeding heavily from the head, "tripped and fell."
Governor Andrew Cuomo called the incident "wholly unjustified and utterly disgraceful," in a tweet.
"Police Officers must enforce - NOT ABUSE - the law," he wrote.
In Indianapolis, police launched an investigation after a video emerged showing at least four officers hitting a woman with batons and firing pepper balls at her on Sunday night.
And in New York City Thursday, officers baton-charged dozens of peaceful protesters defying a curfew in the Bronx after pinning them in, leaving them with nowhere to run, several reports said.
The NYPD made 270 arrests as its officers broke up several protests taking place across the city after the 8:00 pm curfew.
Under-fire New York Mayor Bill de Blasio, who imposed the week-long night-time curfew after widespread looting earlier in the week, has repeatedly said the NYPD is showing "restraint."
In an editorial published Friday, The New York Times called on him to "open your eyes. "The police are out of control," it said.
Floyd, 46, died in the Midwestern city of Minneapolis while handcuffed during a May 25 arrest for a non-violent offense.
His death reignited longstanding resentment over police killings of African-Americans and unleashed a nationwide wave of protest unlike anything seen in the US since Martin Luther King's 1968 assassination.
Mass protests have also taken place in European capitals and on Friday Canadian Prime Minister Justin Trudeau joined a large demonstration in Ottawa.
The action has posed Trump with one of the greatest challenges of his tumultuous presidency.
While condemning Floyd's death, he has adopted a tough stance towards the protesters and has been accused of exacerbating tensions.
US civil rights groups have filed a case suing Trump after security forces fired pepper balls and smoke bombs to clear peaceful demonstrators in Washington before the president walked to a church for a photo op earlier this week.
Mayor Muriel Bowser Friday renamed the area outside the White House "Black Lives Matter Plaza" -- unveiling a giant street mural -- after tweeting a letter calling on Trump to "withdraw all extraordinary federal law enforcement and military presence from our city."
But Trump was back in buoyant mood following the release of strong job numbers Friday.
He told reporters that such violence as Floyd's death in handcuffs cannot be allowed to happen.
Nevertheless, Trump added, "Hopefully George is looking down right now and saying this is a great thing for our country." "This is a great day for him. It's a great day for everybody," he said.
Biden immediately slammed Trump for invoking Floyd's name. "George Floyd's last words, 'I can't breathe,' have echoed across our nation and around the world.
"For the President to try to put any other words in his mouth is frankly despicable," he tweeted.
Some of the early protests were marred by rioting and looting but they have been mostly peaceful since then.
Curfews have been lifted in Washington, Los Angeles and other cities but New York's is due to run for the next three nights.
Several thousand marched in Brooklyn on Friday afternoon as activists sought to keep up the movement's momentum into the weekend.
Some of their demands have been met: Derek Chauvin, who knelt on Floyd, has been charged with second-degree murder while three officers who assisted him have been charged with aiding and abetting his murder.
Large protests are planned for Saturday, including in Washington and outside the Trump National Hotel in Miami.
"We're going to keep going until we change the whole system of justice," civil rights leader Al Sharpton said at a memorial for Floyd on Thursday.
