"Certain occupations carry an vast responsibility and none more so than a sworn police officer", Imran Ali, head of the county attorney's major crimes unit, said in a statement.
Potter's case was referred to nearby Washington County under a year-old, five-county agreement to avoid the appearance of conflicts of interest in police use-of-deadly-force cases. Acting City Manager Reggie Edwards said Wednesday that because Potter resigned, she is entitled to "all accrual and benefits that is due".
Wright is then seen breaking free and getting inside the vehicle when Potter yells "Taser, Taser, Taser", before firing a shot from what turned out to be her handgun.
Potter's handgun and Taser were holstered on opposite sides of her belt in such a way that she would have had to use her left hand to draw the electric-stun device, the county attorney's office said.
Mayor Mike Elliott said the city had been moving towards sacking Potter when she submitted her resignation.
"Holy shit, I shot him", she says.
Prosecutors will seek to prove that Potter "abrogated her responsibility to protect the public when she used her firearm rather than her Taser", he said.
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 awful accident.
"While we appreciate that the district attorney is pursuing justice for Daunte, no conviction can give the Wright family their loved one back", said the Wrights' family lawyer Ben Crump after the arrest.
"Kim Potter executed Daunte for what amounts to no more than a minor traffic infraction and a misdemeanour warrant", he said.
Potter is at least the third United States law enforcement officer to face charges after claiming they mistakenly killed someone with a gun when they meant to use a Taser. Mehserle testified at trial that he mistakenly pulled his.40-caliber handgun instead of his stun gun.
The previous two are former Bay Area Rapid Transit (BART) police officer Johannes Mehserle, who fatally shot a man named Oscar Grant in 2009 in Oakland, California, and reserve deputy Robert Bates, who killed Eric Harris in Oklahoma in 2015.
Brooklyn Center had a 10 p.m. curfew Wednesday, the fourth night in a row that the city has taken that action. Elliott, the mayor, urged people to protest without violence, saying "your voices have been heard".
About 24 people were arrested after authorities cleared protesters around the time of Brooklyn Center's 10 p.m. curfew and after dispersal orders were given, Minnesota State Patrol Col. Matt Langer said in a news conference.
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.
An instructor with Brooklyn Center police, Potter was training two other officers when they stopped Wright, the Minnesota Police and Peace Officers Association told the Star Tribune newspaper.
Outside Potter's home in Champlin, north of Brooklyn Center, concrete barricades and tall metal fencing had been set up and police cars were in the driveway.
Despite a steady flurry of snow, protesters rallied outside the Brooklyn Center police headquarters for hours on Tuesday evening to make their frustrations known. After Floyd's death a year ago, protesters demonstrated several times at the home of Derek Chauvin, the former Minneapolis officer now on trial in Floyd's death.
Chauvin, who is white, was seen in a video taken by a bystander kneeling on Floyd's neck for more than nine minutes as the handcuffed 46-year-old complained repeatedly that he "can't breathe".
However, Elliott has acknowledged that the police force has "very few people of color".
