The killing has sparked three nights of clashes between police and protesters.
The veteran officer, who has worked for the department for 26 years but allegedly confused her gun for a taser, resigned from the force Tuesday as protests erupted in the city demanding justice for Wright. However, protesters and Wright's family members say there's no excuse for the shooting and that it shows how the justice system is tilted against Black people, noting that Wright was stopped for expired vehicle registration and ended up dead.
"Certain occupations carry an huge responsibility and none more so than a sworn police officer", Imran Ali, assistant criminal division chief and director of the major crimes unit for the County Attorney's Office, said in the statement.
Under Minnesota law, second-degree-murder is when a person causes another person's death by 'culpable negligence whereby the person creates an unreasonable risk, and consciously takes chances of causing death or great bodily harm to another'. An attorney for Potter did not immediately respond to messages from The Associated Press.
In a press conference on Wednesday, Wright family attorney Ben Crump and Rev. Al Sharpton praised Orput's quick action to charge Potter - but Sharpton added that he felt a second-degree manslaughter charge was the "least" charge that Potter should face.
The charge carries a maximum sentence of 10 years in prison and a $20,000 fine. She was arrested on Tuesday and later freed after posting a 100,000-dollar (£72,000) bond.
Potter's first court appearance was expected to be via Zoom at 1:30 p.m.
Since Sunday, hundreds of protesters have gathered outside the police station to protest police violence toward Black people. "They're the ones ready for war", she said of the National Guard members and riot police stationed behind fortified fences across the street.
The Star Tribune reported that concrete barricades and tall metal fencing had been set up around Potter's home in Champlin, a suburb north of Brooklyn Center, with police cars guarding the driveway.
Wright was shot dead during a traffic stop by a police officer who apparently confused her handgun with her Taser, in what the force later described as a disgusting accident.
A day earlier Philonise Floyd testified in the case against Derek Chauvin, the former Minneapolis police officer on trial for murder and manslaughter in the case of George Floyd, whose death past year shocked the nation. The warrant was for his failure to appear in court on charges that he fled from officers and possessed a gun without a permit during an encounter with Minneapolis police in June. It showed her approaching Wright as he stood outside of his auto as another officer was arresting him.
After pulling Wright over on Sunday, officers discovered there was a warrant out for his arrest, according to the official police account of the confrontation. I'll Tase you! Taser! Potter shouts, "Taser! Taser!"
Wright's father Aubrey Wright told ABC's Good Morning America Tuesday: 'I can't accept that - a mistake.
"We will vigorously prosecute this case and intend to prove that Officer Potter abrogated her responsibility to protect the public when she used her firearm rather than her Taser", he said.
Experts say cases of officers mistakenly firing their gun instead of a Taser are rare, usually less than once a year nationwide.
The news release announcing the charge noted that Potter holstered her handgun on the right side and her Taser on the left.
Brooklyn Center Mayor Mike Elliott had said he hoped Potter's resignation would "bring some calm to the community", but that he would keep working toward "full accountability under the law".
