Some protests were largely peaceful. Others have fallen into clashes between the police and the demonstrators.
Here’s a breakdown of the troubles.
Friday night’s protests began peacefully, according to the Portland Police Office, which said a crowd gathered outside the Federal Courthouse to listen to speakers.
At around 11 p.m., people started shaking a fence while others were shooting fireworks at it, police said. A large group of peaceful protesters appeared to approach the group, swinging the fence over and trying to defuse the tension, according to a CNN team at the scene.
Police “attempted to disperse the crowd using various ammunition,” the PPB said in a statement. Police said members of the mob had gas masks, shields, leaf blowers, power tools, fireworks and lasers.
Federal agents deployed tear gas and flash bangs behind the fence, erected as a barricade between protesters and the Multnomah County Justice Center, opposite the Federal Courthouse, the CNN team reported. Just before officers released the gas, a crowd of peaceful protesters chanted “Black Lives Matter”.
It is not known whether the police or a federal agency released the gas. Chad Wolf, the acting Secretary of Homeland Security, tweeted that six DHS officers were injured on Friday evening.
The protesters included the so-called “Mommy’s Wall” and a group of veterans who support Black Lives Matter.
A protester who only provided her first name, Victoria, told CNN she joined the protests because of her outrage over the death of George Floyd.
“This is not the America I want to live in,” she said. “I just can’t stay home (with) everything that is going on, and I have to stand up and lend my voice to the important work that the black community has always done, ignored by mainstream America and ignored by the institutions that exist. ”
The protests continued on Saturday evening. In a series of tweets, police told protesters to disperse, citing “the violent behavior of people in the city center” and warning that they would deploy tear gas.
Other incidents in the past week have only increased tension in the city. Last weekend, a 53-year-old Navy veteran told CNN he was beaten and pepper sprayed by law enforcement officers. And on Wednesday, Portland Mayor Ted Wheeler was hit by tear gas after joining protesters outside the Federal Courthouse.
It is not known which agency deployed the tear gas, but Portland police said they did not deploy CS gas, a commonly used type of tear gas.
Dozens of people have been arrested during protests this weekend in Seattle. This week, DHS officials told CNN that a U.S. Customs and Border Protection response team would be dispatched there to stay on standby to help protect federal facilities.
Forty-seven people were arrested on various counts, including non-dispersal and obstruction, according to a Seattle Police press release on Sunday.
According to this statement, 59 police officers were injured. The injuries included abrasions, bruises, burns and a torn meniscus.
Protesters threw stones, bottles, fireworks and other explosives at police officers, police said.
Protesters also entered a construction site at a local courthouse, where they torched portable trailers and smashed windows of personal vehicles in the area, police said in a separate statement. Some demonstrators then moved on and smashed the windows of several businesses on 12th Avenue.
In recent weeks, protesters in Louisville have been protesting the police gunshot death of Breonna Taylor in March, still fueled by the Black Lives Matter movement after Floyd’s death.
Seventy-six people were arrested Friday night for allegedly blocking a street with barrels filled with water, urine and bleach, according to Louisville Metro Police Department deputy chief LaVita Chavous. Some protesters reportedly threw water bottles at the police. The charges include assault and disorderly conduct, Chavous said.
On Saturday, a black group calling themselves the Not F ** king Around Coalition gathered in Louisville to seek justice in Taylor’s case, according to CNN-affiliated WAVE. The group coordinated the event with the Louisville Metro Police Department in order to maintain security, the group leader told WAVE.
“We are not here to wreak havoc,” said John Fitzgerald Johnson. “There were rumors that we were coming to hunt people down. Again, we are simply exercising our constitutional rights to assemble and bear arms. “
Saturday’s protests were largely peaceful, police said. However, three NFAC members suffered non-life threatening injuries after being shot after discharging a firearm, according to the LMPD. There are no outstanding suspects, said LMPD chief Robert Schroeder.
Eleven people were arrested on Saturday, LMPD said. Protesters had marched to Lynn Stadium, police said, where some walked through a door. Others have used cars to block a bridge.
The protests in Oakland, Calif., Started as a peaceful march to show solidarity with the protesters in Portland, according to CNN affiliate KGO.
But on Saturday night, police declared the protest illegal and called on protesters to disperse after some protesters allegedly threw projectiles and pointed “illegal” lasers at officers, police said.
Protesters knocked down barricades outside police headquarters, police said. Authorities shared images of a firecracker, blue paint splattered on the side of the building and a shattered glass door leading inside.
“We are using signs and giving voice orders to the crowd if the assaults continue, chemicals will be deployed,” the Oakland Police Department said on Twitter.
Aurora was convulsed by the death of a black man, Elijah McClain, who died last August after a confrontation with Aurora cops – a case that has drawn renewed attention amid national anger over Floyd’s murder.
Protests over McClain’s death took a violent turn on Saturday when someone drove a vehicle through a crowd of protesters marching on a freeway, police said in a tweet.
“We are in contact with this vehicle and are investigating,” police said.
Police told CNN that there were no reports that anyone was injured by the vehicle.
Police later said that a “protester decided to shoot a gun, hitting at least one other protester.” The victim was taken to hospital in stable condition. Another person went to the hospital with a “scratch wound,” police said.
“The current Black Lives Matter movement is one of the greatest social justice movements in American history,” said participant Apryl Alexander, CNN affiliate KMGH.
“It creates change,” she said. “We create laws. We are raising awareness across the country and around the world about the issues of police brutality, so they are critical.
The majority of the protesters were peaceful, but one group caused “major damage” to a courthouse, police said on Twitter, sharing photos of shattered windows and shattered fences.
The shooting death of a protester eclipsed protests in Austin on Saturday night.
An adult man, identified by police on Sunday night as Garrett Foster, 28, died after gunfire at protesters, police spokeswoman Katrina Ratcliff said. A suspect is in custody and is cooperating with the police.
Officers were monitoring protests on Congress Avenue when shots were fired shortly before 10 p.m. local time, Ratcliff said. Police located the victim, who had sustained a gunshot wound, and transported him to hospital, where he was pronounced dead.
Early reports suggest the victim could have carried a gun and approached the suspect’s vehicle, Ratcliff said, before the suspect shot the victim from inside the vehicle.
