Americans awoke Sunday to charred and glass-strewn streets in dozens of cities after another night of unrest fueled by rage over the mistreatment of African Americans at the hands of police, who responded to the violence with tear gas and rubber bullets.

Tens of thousands marched peacefully through streets to protest the death of George Floyd, a black man who died Monday after a white Minneapolis police officer pressed his knee on his neck until he stopped breathing. But many demonstrations sank into chaos as night fell: Cars and businesses were torched. The words “I can’t breathe” were spray-painted all over buildings. A fire in a trash bin burned near the gates of the White House.

The fury sparked by Floyd’s death was compounded by the coronavirus pandemic, which has left millions out of work and killed more than 100,000 people in the U.S., including disproportionate numbers of black people.

“We’re sick of it. The cops are out of control,” protester Olga Hall said in Washington, D.C. “They’re wild. There’s just been too many dead boys.”

People set fire to squad cars, threw bottles at officers and busted windows of storefronts, carrying away TVs and other items even as some protesters urged them to stop. In Indianapolis, multiple shootings were reported, including one that left a person dead amid the protests, adding to deaths in Detroit and Minneapolis in recent days.

In Minneapolis, the city where the protests began, police, state troopers and National Guard members moved in soon after an 8 p.m. curfew took effect to break up the demonstrations.

At least 13 police officers were injured in Philadelphia , and at least four police vehicles were set on fire. In New York City, dangerous confrontations flared repeatedly as officers made arrests and cleared streets. A video showed two NYPD cruisers lurching into a crowd of demonstrators who were pushing a barricade against one of them and pelting it with objects. Several people were knocked to the ground. It was unclear if anyone was hurt.

“The mistakes that are happening are not mistakes. They’re repeated violent terrorist offenses, and people need to stop killing black people,” Brooklyn protester Meryl Makielski said.

Overnight curfews were imposed in more than a dozen major cities nationwide, including Atlanta, Denver, Los Angeles, Minneapolis, San Francisco and Seattle.

Few corners of America were untouched, from protesters setting firesinside Reno’s city hall, to police launching tear gas at rock-throwing demonstrators in Fargo, North Dakota. In Salt Lake City, demonstrators flipped a police car and lit it on fire. Police said six people were arrested and an officer was injured after being struck in the head with a baseball bat.

By daybreak, cleanup had already began in Nashville along Broadway Street — known for its famous honky tonks — after protesters broke windows, lit fires and destroyed light poles. Police said in a tweet that at least 30 businesses and buildings were damaged.

Republican Georgia Gov. Brian Kemp authorized the deployment of up to 3,000 National Guard troops to Athens, Savannah and any other cities where more demonstrations were planned Sunday. Kemp had already approved up to 1,500 Guardsmen to help enforce a 9 p.m. Saturday curfew in Atlanta.

“The protesters need to know we’re going to support their efforts in a peaceful, nonviolent protest,” Kemp told television station WSB late Saturday. “The agitators need to know that we’ll be there ... to take them to jail if they’re destroying lives and property.”

President Donald Trump appeared to cheer on the tougher tactics Saturday night, commending the National Guard deployment in Minneapolis, declaring “No games!” and saying police in New York City “must be allowed to do their job!”

Presumptive Democratic presidential nominee Joe Biden condemned the violence as he continued to express common cause with those demonstrating after Floyd’s death.

“The act of protesting should never be allowed to overshadow the reason we protest,” Biden said in a statement Saturday night.

In Ferguson, Missouri, where Michael Brown Jr. was shot and killed by a white police officer in 2014, sparking a wave of protests throughout the country, six officers were hurt after being hit with rocks and fireworks.

Police have arrested nearly 1,700 people in 22 cities since Thursday, according to a tally by The Associated Press. Nearly a third of those arrests came in Los Angeles, where the governor declared a state of emergency and ordered the National Guard to back up the city’s 10,000 police officers as dozens of fires burned across the city.

This week’s unrest recalled the riots in Los Angeles nearly 30 years ago after the acquittal of the white police officers who beat Rodney King, a black motorist who had led them on a high-speed chase. The protests of Floyd’s killing have gripped many more cities, but the losses in Minneapolis have yet to approach the staggering totals Los Angeles saw during five days of rioting in 1992, when more than 60 people died, 2,000-plus were injured and thousands arrested, with property damage topping $1 billion.

But not all protests were marred by violence. In Juneau, Alaska, local police joined protesters at a rally in front of a giant whale sculpture on the city’s waterfront.

“We don’t tolerate excessive use of force,” Juneau Police Chief Ed Mercer told a gathering where most people wore masks and some sang Alaska Native songs.

The show of force in Minneapolis came after three days in which police largely avoided engaging protesters, and after the state poured more than 4,000 National Guard troops into Minneapolis. Authorities said that number would soon rise to nearly 11,000.

“The situation in Minneapolis is no longer in any way about the murder of George Floyd,” said Gov. Tim Walz, who also said local forces had been overmatched the previous day. “It is about attacking civil society, instilling fear and disrupting our great cities.”

Some residents were glad to see the upheaval dissipating.

“l live here. I haven’t been able to sleep,” said Iman Muhammad, whose neighborhood saw multiple fires set Friday night. Muhammad said she sympathized with peaceful protests over Floyd’s death but disagreed with the violence: “Wrong doesn’t answer wrong.”
