(CNN) — Protesters blocked roads in St. Louis on Saturday night on a second day of demonstrations after the acquittal of a former police officer who was charged with first-degree murder.
Saturday’s demonstrations started as Friday’s did, with a few hundred people marching peacefully in streets near downtown and heated up as they continued into the night.
A pocket of protesters threw bricks, rocks and projectiles with paint at police as officers tried to disperse the crowds.
Nine people were arrested Saturday night during the protests, two police departments in the area said.
Video footage showed at least eight people in police custody after protesters shattered the windows of numerous businesses Saturday night.
One man told CNN’s Ryan Young he was there to voice his frustration, though he didn’t pinpoint why he was discouraged.
Some people vented about the court’s decision to acquit Jason Stockley, who as an officer in 2011 shot and killed a motorist. Demonstrators also called for some city leaders to step down.
A female protester said she was sad all day and had tried to distract herself.
“Eventually I just had to come out and do something,” she said. “It feels like a parade for peace.”
Demonstrators briefly invaded two area malls earlier in the day. The city had been on edge for days during the trial. Protests Friday night were mostly peaceful, but after dark there was violence.
A group of protesters Saturday marched through the West County Center Mall in Des Peres, Missouri, chanting “No justice, no profits.” Security officers estimated there were between 200 and 300 protesters marching peacefully.
Many chanted, “Black lives matter,” video on social media shows. Stockley is white; the man he killed was black.
CNN affiliate KMOV said the mall protest lasted about an hour. Protesters also marched through Chesterfield Mall near St. Louis.
Legendary rock band U2 announced on its website that it canceled a show scheduled for Saturday night in St. Louis because police could not provide enough officers as a security detail for the concert. An Ed Sheeran concert at the Scottrade Center — primarily used for the city’s National Hockey League team — was also canceled for the same reason, a statement on the venue’s website said.
Rocks at the mayor’s house
Demonstrations on Friday night were at times violent.
Some protesters locked arms and prayed together, but within hours others smashed the windshield of a police vehicle and threw water bottles, rocks and bricks at law enforcement.
St. Louis police said the demonstrators later threw rocks at the mayor’s home.
At least 33 people were arrested, most of whom were from St. Louis or the surrounding area, according to a police tweet.
A total of 11 law enforcement officers were injured in protests. Nine St. Louis Metropolitan Police Department officers, one officer with the county and one Missouri State Highway Patrol trooper were injured during protests on Friday night, St. Louis Metro Police Department Chief Lawrence O’Toole said.
The injuries ranged from a possible broken jaw to a dislocated shoulder. Six were treated at hospitals and released, police said Saturday. There were no reports of protesters being injured, the chief added.
O’Toole said Friday night that his officers showed great restraint despite injuries.
Video footage showed officers using tear gas to disperse the crowds after police said the protests were considered an unlawful assembly. O’Toole said his officers used pepper balls.
Police recovered one pistol, according to a department tweet.
O’Toole and Mayor Lyda Krewson said Saturday a vast majority of the protests were peaceful, but the chief said trouble started after nightfall.
Former officer: I thought man was reaching for gun
In December 2011, Stockley, then a St. Louis officer, fatally shot Anthony Lamar Smith, 24, after a police chase over a suspected drug deal.
Friday, Smith’s mother went to the site of the deadly shooting.
“(My son) wasn’t wrong. I felt like the verdict was wrong,” Annie Smith told CNN affiliate KTVI. “The judge made the wrong decision. … Justice wasn’t served. I (didn’t) get … justice. I could never be at peace.”
Smith’s brother told KTVI he thinks the judge didn’t care about the case and already had his mind made up before the trial. He said the family will look at other legal steps.
“This case ain’t over,” Antwan Johnson said.
Stockley expressed a sense of relief after the acquittal and said he felt vindicated that the judge ruled he had done nothing wrong.
“It feels like a burden has been lifted, but the burden of having to kill someone never really lifts,” Stockley told the St. Louis Post-Dispatch, which is a CNN affiliate.
“The taking of someone’s life is the most significant thing one can do, and it’s not done lightly. … My main concern now is for the first responders, the people just trying to go to work and the protesters. I don’t want anyone to be hurt in any way over this.”
Stockley said that before firing his weapon, he ordered Smith to show his hands, and he believed the suspect was reaching for a handgun between the center console and the passenger seat, according to a police department report obtained by the Post-Dispatch.
In the report, Stockley said he entered Smith’s car “to locate the weapon and render it safe,” and removed the ammunition from the silver revolver.
During the trial, prosecutors argued that a revolver found in Smith’s car had been planted by Stockley to justify the shooting, but the gun was never seen from the multiple cameras that captured Stockley and other officers at the scene.
He said he understood the video of the shooting looked bad to investigators and the public.
“Every resisting (arrest) looks bad. It never looks good,” Stockley said. “But you have to separate the optics from the facts.”
State and federal authorities did not initially prosecute Stockley, but in the aftermath of the Ferguson protests aftermath, then-St. Louis Circuit Attorney Jennifer Joyce charged him with first-degree murder in May 2016, citing new evidence.
He pleaded not guilty to the first-degree murder charge and waived his right to a jury trial, meaning the ruling was left to the judge.
In Friday’s ruling, St. Louis Circuit Judge Timothy Wilson said the prosecution’s argument was “not supported by the evidence.” The gun was too large, Wilson said, for Stockley to hide it from the cameras at the scene.
“I can feel for and I understand what the family is going through, and I know everyone wants someone to blame, but I’m just not the guy,” Stockley said in the interview with the Post-Dispatch.
Stockley left the St. Louis Metropolitan Police Department in August 2013. Later that year, the St. Louis police board settled a wrongful death suit with Smith’s survivors for $900,000.
