The Memphis police chief on Saturday disbanded the citys so-called Scorpion unit, citing a “cloud of dishonor” from newly released video that showed some of its officers beating Tyre Nichols to death after stopping the Black motorist.

Police Director Cerelyn “CJ” Davis acted a day after the harrowing video emerged, saying she listened to Nichols relatives, community leaders and uninvolved officers in making the decision. Her announcement came as the nation and the city struggled to come to grips with the violence of the officers, who are also Black. The video renewed doubts about why fatal encounters with law enforcement keep happening despite repeated calls for change.

Protestors marching though downtown Memphis cheered when they heard the unit had been dissolved. One protestor said over a bullhorn that “the unit that killed Tyre has been permanently disbanded.”

Referring to “the heinous actions of a few” that dishonored the unit, Davis contradicted an earlier statement that she would keep the unit. She said it was imperative that the department “take proactive steps in the healing process.”

“It is in the best interest of all to permanently deactivate the Scorpion unit,” she said in a statement. She said the officers currently assigned to it agreed “unreservedly.”

The unit is composed of three teams of about 30 officers who target violent offenders in areas beset by high crime. It had been inactive since Nichols Jan. 7 arrest.

Scorpion stands for Street Crimes Operations to Restore Peace in our Neighborhoods.

In an interview Friday with The Associated Press, Davis had said she would not shut down a unit if a few officers commit “some egregious act” and because she needed it to continue to work.

“The whole idea that the Scorpion unit is a bad unit, I just have a problem with that,” Davis said then.

She became the first Black female chief in Memphis one year after George Floyd was killed at the hands of Minneapolis police. At the time she was chief in Durham, North Carolina, and responded by calling for sweeping police reform.

Ben Crump and Antonio Romanucci, lawyers for the Nichols family, said the move was “a decent and just decision.”

“We must keep in mind that this is just the next step on this journey for justice and accountability, as clearly this misconduct is not restricted to these specialty units. It extends so much further,” they said.

The five disgraced officers - Tadarrius Bean, Demetrius Haley, Desmond Mills Jr., Emmitt Martin III and Justin Smith - have been fired and charged with murder and other crimes in Nichols death, which came three days after the arrest. They face up to 60 years in prison if convicted of second-degree murder.

The video images released Friday show police savagely beating the 29-year-old FedEx worker for three minutes while screaming profanities at him in an assault that the Nichols family legal team has likened to the infamous 1991 police beating of Los Angeles motorist Rodney King. Nichols calls out for his mother before his limp body is propped against a squad car and the officers exchange fist-bumps.

The video also left many unanswered questions about the traffic stop and about other law enforcement officers who stood by as Nichols lay motionless on the pavement.

“Nobody tried to stop anything. They have a duty to intervene, a duty to render care,” Brenda Goss Andrews, president of the National Organization of Black Law Enforcement Executives, said in an interview after viewing the video.

She also was struck by the immediate aggression from officers as soon as they got out of the car: “It just went to 100. ... This was never a matter of de-escalation,” Goss Andrews said, adding, “The young man never had a chance from the moment that he was stopped.”

Davis has said other officers are under investigation, and Shelby County Sheriff Floyd Bonner said two deputies were relieved of duty without pay while their conduct is investigated.

Rodney Wells, Nichols stepfather, said the family would “continue to seek justice” and those who failed to render aid are “just as culpable as the officers who threw the blows.”

A Memphis police spokeswoman declined to comment on the other officers conduct.

Cities nationwide had braced for demonstrations after the video emerged, but protests were scattered and nonviolent. Several dozen demonstrators in Memphis blocked the Interstate 55 bridge that carries traffic over the Mississippi River toward Arkansas. Protesters also blocked traffic in New York City, Los Angeles and Portland, Oregon.

Blake Ballin, the lawyer for Mills, told AP in a statement Saturday that the videos “produced as many questions as they have answers.”

Some of those will focus on what Mills “knew and what he was able to see” and whether his actions “crossed the lines that were crossed by other officers during this incident,” Ballin said.

Davis acknowledged that the police department has a supervisor shortage and said the lack of a supervisor in the arrest was a “major problem.” City officials have pledged to provide more of them.

Its not clear why the traffic stop happened in the first place. One officer can be heard on video saying that Nichols wouldnt stop and then swerved as though he intended to hit the officers car. The officer says that when Nichols pulled up to a red light, the officers jumped out.

But Davis said the department cannot substantiate the reason for the stop.

“We dont know what happened,” she said, adding, “All we know is the amount of force that was applied in this situation was over the top.”

After the first officer roughly pulls Nichols out of the car, Nichols can be heard saying, “I didnt do anything,” as a group of officers begin to wrestle him to the ground.

One is heard yelling, “Tase him! Tase him!”

Nichols calmly says, “OK, Im on the ground,” and that he was just trying to go home. Moments later, he yells at them to “stop.”

Nichols is then seen running as an officer fires a Taser. The officers start chasing Nichols.

Others are called, and a search ensues before Nichols is caught at another intersection. His mothers home, where he lived, was only a few houses away, and his family said he was trying to get there.

The officers beat him with a baton, and kick and punch him. The attack continues even after he collapses.

It takes more than 20 minutes afterward before any sort of medical attention is provided.

During the wait for an ambulance, officers joke and air grievances. They complain that a handheld radio was ruined, that someone lost a flashlight, that multiple officers were caught in the pepper spray used against Nichols.

Throughout the videos, they make claims about Nichols behavior that are not supported by the footage or that the district attorney and other officials say did not happen. In one, an officer claims that during the initial traffic stop Nichols reached for the officers gun and almost had his hand on the handle, something not shown in the video.

After Nichols is in handcuffs and leaning against a police car, several officers say he must have been high. Later one says no drugs were found in Nichols car, and another immediately counters that he must have ditched something while running away.

During a speech Saturday in Harlem, the Rev. Al Sharpton said the beating was particularly egregious because the officers were Black, too.

“Your Blackness will not stop us from fighting you. These five cops not only disgraced their names, they disgraced our race,” Sharpton said.
