ST. LOUIS -- Noisy demonstrators disrupted shopping at upscale suburban St. Louis shopping malls and marched through a popular district of bars and restaurants Saturday in peaceful protests over the acquittal of a white St. Louis police officer who fatally shot a black man, and there was little sign of the sporadic vandalism and violence that marred the rallies a night earlier.

A few hundred people shouted slogans such as "black lives matter" and "it is our duty to fight for our freedom" as they marched through West County Center mall in the city of Des Peres, west of St. Louis, to decry the judge's verdict Friday clearing ex-officer Jason Stockley of first-degree murder in the 2011 shooting of Anthony Lamar Smith.

A short time later, a group demonstrated at Chesterfield Mall in the suburbs and a regional food festival.

On Saturday evening, hundreds of protesters marched through the Delmar Loop of the St. Louis suburb of University City - known for concert venues, restaurants, shops and bars and including the famous Blueberry Hill where rock legend Chuck Berry played for many years. After three hours, organizers asked protesters to disband and reconvene Sunday afternoon.

Drums accompanied the marchers as they chanted in unison, CBS affiliate KMOV-TV reports. After marching back to their starting point in the Delmar Loop, organizers of the protest told the group to leave and regroup downtown on Sunday.

Small groups of protesters remained, but police said they were not aware of any arrests on Saturday.

The peaceful protests followed raucous Friday marches in downtown St. Louis and through the city's posh Central West End area during the night. More than 20 people were arrested Friday night and 10 officers were injured.

Protesters wanted the entire region, not just predominantly black areas, to feel the impact of the protests. At one point, protesters threw rocks and splashed red paint on Mayor Lyda Krewson's home.

"I don't think racism is going to change in America until people get uncomfortable," said Kayla Reed of the St. Louis Action Council, a protest organizer.

Susanna Prins, 27, a white woman from University City, carried a sign reading, "White silence is violence."

"Not saying or doing anything makes you complicit in the brutalization of our friends and neighbors," Prins said.

Smith's death is just one of several high-profile U.S. cases in recent years in which a white officer killed a black suspect, including the 2014 killing of Michael Brown in nearby Ferguson that sparked months of angry and sometimes violent protests.

Federal prosecutors said Saturday they won't open a new civil rights investigation into the killing, as the NAACP requested. Justice Department spokeswoman Lauren Ehrsam said the department concluded in September not to prosecute, but didn't announce it then to avoid affecting the state criminal case.

Police were prepared for a second night of trouble after Friday's demonstrations led to several clashes - including rocks thrown at a police car and objects tossed at officers in riot gear - and culminated when protesters broke a window and spattered red paint on the home of Mayor Lyda Krewson. Police eventually used tear gas to clear the area.

Krewson said she was not home at the time but her family was. She said it was "irritating" to have her house vandalized.

"This story is not about whether I got my windows broken or not. This is about coming together to have a better St. Louis for all of us," she told a news conference Saturday.

Reed said protesters went to Krewson's house because she was not in the streets with the people even though she had expressed support on social media.

Nearly three-dozen people were arrested Friday, police said, mostly for failure to disperse, resisting and interfering.

Police said 11 officers were injured Friday, including a broken jaw and dislocated shoulder. Five officers were taken to hospitals. Police also said that 10 businesses were damaged, mostly broken windows.

Gov. Eric Greitens, a Republican, was highly critical during last year's campaign of how the Ferguson protests were managed. Greitens put the National Guard on standby before the verdict Friday, and some troops were deployed to guard fire stations and unspecified "critical infrastructure."

Anticipating more demonstrations, concerts Saturday by U2 and Sunday by English singer-songwriter Ed Sheeran were canceled because the police department said it wouldn't be able to provide its standard protection for the event, organizers said.

The civil disobedience followed the acquittal of Stockley for fatally shooting Smith, 24, after the suspected drug dealer fled from officers trying to arrest him.

Stockley testified he felt he was in danger because he saw Smith holding a silver revolver when the suspect backed his car toward officers and sped away.

Prosecutors said Stockley planted a gun in Smith's car after the shooting. The officer's DNA was on the weapon but Smith's wasn't. Dashcam video from Stockley's cruiser recorded him saying he was "going to kill this (expletive)." Less than a minute later, he shot Smith five times.

Stockley's lawyer dismissed the comment as "human emotions" during a dangerous pursuit. St. Louis Circuit Judge Timothy Wilson, who said prosecutors didn't prove beyond a reasonable doubt that Stockley murdered Smith, said the statement could be ambiguous.

Stockley, 36, who left the force in 2013 and moved to Houston, told the St. Louis Post-Dispatch after the verdict that he understands how the video looks bad, but insisted he did nothing wrong.

"I know everyone wants someone to blame, but I'm just not the guy," Stockley said.
