LOS ANGELES (CNS) - A crowd of roughly 200 protested outside Los Angeles Police Department headquarters following the release of graphic video depicting the fatal beating of a 29-year-old Black man by five former Memphis police officers, with some surrounding parked police cars -- banging on them and smacking windows -- but no arrests were made and most left after being warned by officers at the scene, authorities said Saturday.

The group had marched through downtown Los Angeles carrying Black Lives Matter banners and smartphones before gathering at First and Main streets shortly after 8 p.m. for a candlelight vigil for Tyre Nichols and also Keenan Anderson, who died in LAPD custody Jan. 6 after being repeatedly shot by a Taser that witnesses said later became a "street takeover," and tense standoff with officers in riot gear.

After convening in front of LAPD headquarters, the protesters knocked down metal protective barriers and someone spray painted the word "kills" on the building under the words Los Angeles Police Department, the Los Angeles Times reported.

Similar demonstrations took place across the nation Friday night following the release of the video that was widely decried by citizens, elected officials and law enforcement.

"The grotesque actions I watched in the video were incredibly disturbing, cruel and inhumane," Los Angeles Police Department Chief Michel Moore said in a statement. "To witness former Memphis police officers engaged in such unjustified and excessive force at the expense of Tyre Nichols' life angers me as a police officer, as an American.

"This behavior goes against every principle of the law enforcement profession and is in direct contradiction to the dedication and sacrifice of the vast majority of our members who strive to protect and serve. The violation of trust tarnishes our badge and has a caustic effect on the public's trust."

The Association For Los Angeles Deputy Sheriffs called the video "shocking and disturbing.

"The acts committed have no explanation and illustrate disregard for human life," the group said in a statement. "Those of us in law enforcement take an oath to uphold the law, but men and women in uniform across this country also go about this daily task while respecting the public. As one of the largest law enforcement unions, ALADS and its members remain committed to working together to continue to build on the improvements we have made in the last two years. Unfortunately, this tragic incident forces all of us to pause and reflect."

Long Beach police Chief Wally Hebeish called the video "disturbing and appalling."

"As a profession, we are required to de-escalate situations, intervene when necessary and strive to find peaceful resolutions to incidents," Hebeish said. "The actions depicted in the video of the former Memphis police officers are intolerable."

The disturbing video depicts a Jan. 7 traffic stop in Memphis that led to the death in a hospital three days later of Tyre Nichols. Five Black police officers allegedly involved in the confrontation and beating of Nichols were fired last week, and all were charged this week with second-degree murder and other offenses.

The video shows the officers repeatedly beating the man, even as he is on the ground. Toward the end, Nichols is heard screaming for his mother.

Civil rights attorney Ben Crump, who represents Nichols' family and also represented George Floyd's family, has hailed Memphis officials for acting swiftly to fire the officers involved and charge them with murder. But he compared the video of Nichols' beating to that of King.

"Regrettably, it reminded us of (the) Rodney King video," Crump said. "Regrettably, unlike Rodney King, Tyre didn't survive."

The 1991 LAPD beating of Rodney King led to an overhauling of LAPD management and ultimately sparked the 1992 Los Angeles riots that left more than 60 people dead and caused more than $1 billion in damage.

Los Angeles Mayor Karen Bass issued a statement saying her heart "aches for Tyre's family and all who loved him."

"Our country has a problem that we cannot run away from -- we must confront it," Bass said. "All communities deserve police that will always protect them. It is commendable that the Police Chief and officials in Memphis fired, arrested and filed murder charges against these officers. True justice, however, is not a guilty verdict. True justice would be Tyre being alive today. As the people of Los Angeles process and react to this horrific killing, we must move with purpose and peace."

Gov. Gavin Newsom sent condolences to Nichol's family and friends and said he should be alive Saturday.

"The video released shows abhorrent behavior and these officers must be held accountable for their deadly actions and clear abuse of power," the governor said in a statement Friday. "Today, we are a country in mourning, and must continue our work nationwide to push reforms to prevent excessive use of force and save lives."

Law enforcement agencies across the Southland were on standby throughout the day Friday awaiting the release of the video by Memphis officials, prepared to respond to any protests that might result.

Moore said in his statement the LAPD was prepared to facilitate peaceful protests, and he asked residents to "remain peaceful and unified in their expression of outrage."

A group of community activists gathered in Leimert Park on Friday morning ahead of the video's release, calling for peaceful protests, and urging residents to gather to watch the video "collectively as one."

Activist Najee Ali noted that after the 2020 death of George Floyd at the hands of Minneapolis police, Los Angeles "exploded with different protests ... all over L.A. County."

Rodney King's daughter, Lora Dene King, joined the group Friday afternoon to watch the video when it was released. Earlier in the day, she issued a statement decrying the police assault of Nichols as "extremely sickening."

"We should not have to witness such things in this world over and over with a different name behind the hashtags," she said.

"Watching these type of videos has become very disturbing. It triggers past beatings often in comparison to my father's brutal 1991 beating with the LAPD. This is something I will never understand. I wish to send the family God's Grace and mercy and strength to keep his legacy and good deeds alive as well. I am happy to know he (Nichols) loved skateboarding like my father. I hope his family find strength the most; in the days to come."

The Los Angeles Police Protective League -- the union representing LAPD officers -- issued a joint statement Friday night with the San Francisco Police Officers Association, San Jose Police Officers' Association, and the State of Hawaii Organization of Police Officers blasting the actions of officers in the video.

"The killing of Tyre Nichols at the hands of the five cowardly former Memphis police officers is repugnant and the complete antithesis of how honorable law enforcement professionals conduct themselves every day," the statement read. "These accused individuals were fired, charged with murder and other crimes, arrested, fingerprinted, photographed and jailed, just like any other suspected criminal. Their brutalization of Mr. Nichols was horrific and for his family to have to view the video of Tyre suffering through those evil acts is unfathomable. We pray that they find the strength to deal with this unmitigated loss."

William Briggs, president of the Los Angeles Police Commission, called the beating of Nichols "savage and unconscionable."

"The behavior of these officers must be condemned," Briggs said. "Not just by members of the law enforcement community, but by all Americans. They will answer for their actions; their disregard for human life; their excessive use of force; their failure to intervene and render aide; their violation of the public's trust."

Glendale Police Chief Manuel Cid said the actions in the video "can only be described as police brutality and a lack of humanity."

"These police officers do not represent our agency or the greater law enforcement community," Cid said. "The Glendale Police Department and I condemn their actions in the strongest possible terms and extend our deepest condolences to the victim's family and loved ones."

El Monte Police Chief Jake Fisher added, "The El Monte PD strongly believes in accepting individual and collective responsibility for our oath, duty, and actions. We will continue to adhere to strict standards of conduct in keeping with our ethical obligations while respecting the value of human life and dignity."

The Long Beach Police Department issued a statement earlier Friday saying the agency was on a Stage 2 Tactical Alert in preparation for possible protests.

"This means we will have additional officers on patrol ready to respond to calls for service or any other incidents that may develop," according to LBPD. "We currently have no information of planned protest activity in our city."

Orange County Sheriff Don Barnes, in a statement on social media, said his agency was on standby.

"We understand there may be strong reactions to the incident described by the Memphis police chief as `reckless and inhumane,"' Barnes said. "At this time, we do not have information that any significant events will occur locally related to the release of this video. Our department will protect the First Amendment rights of those who peacefully demonstrate. We are also appropriately prepared and ready to respond if anyone attempts to act criminally."
