In his remarks, Mr Ijames added that officers had to operate under the assumption that Mr Wright "very likely could have a gun".

Under Minnesota state law, a person can be found guilty of second-degree manslaughter if it is proven that they demonstrated negligence by creating unreasonable risk and "consciously take chances of causing death or great bodily harm" to another person.

Ms Potter resigned from the police force two days after the incident. In court, she said that "she did not want anything bad to happen to the city" following the shooting, which had received widespread attention.

Another defence witness, use-of-force expert and former Springfield, Missouri assistant police chief Stephen Ijames, said he believed that the officers were legally bound to attempt to arrest Mr Wright as a result of an outstanding warrant for a weapons violation.

Over several days of testimony, prosecutors alleged that Ms Potter should have known the difference between her gun and a Taser. Assistant Minnesota Attorney General Erin Eldridge said the case was about "recklessness and negligence".

A former Minnesota police officer has tearfully recounted the "chaotic" moment she shot and killed a black motorist in April.

Earlier this week, jurors also heard from Mr Wright's father Arbuey, who said Daunte was loved and missed by his family.

In his testimony, Mr Gannon said that his own experiences being dragged by a car during an arrest left him with a feeling of "sheer terror" and "simply trying to survive".

Additionally, Ms Potter said that she had been trained on Tasers since 2002, and had drawn the weapon for "de-escalation" multiple times in her career, but never fired it.

"I remember yelling 'Taser, Taser, Taser', and nothing happened. Then he told me I shot him," she added, breaking down in tears.

He also said that deadly force is warranted in instances in which a police officer is partially inside a car that is attempting to flee. During the incident that led to Mr Wright's death, two officers were attempting to remove him from the vehicle when the shooting took place.

Footage of the incident shown in court last week shows Ms Potter repeatedly yelling "Taser" before firing a single shot from her pistol. She is later seen sitting on the pavement in tears.

Mr Ijames' testimony stood in stark contrast to use-of-force expert Seth Stoughton, who told the jury that even the use of a Taser would have been "unreasonable" during the incident.

"[A police officer] would not have concluded that there was an imminent threat of death or great bodily harm, and thus the use of force was excessive," he said.

Testifying in her own defence for the first time on Friday, Ms Potter said that she was standing near the vehicle as Mr Wright and another officer, Mychal Johnson, struggled during the attempted arrest.

Ms Potter's attorneys have argued that the use of force - including deadly force - was justified, claiming that Mr Wright endangered the officers in an attempt to flee from the arrest.

The defence rested its case on Friday afternoon after two days of testimony in which they called eight witnesses, including Ms Potter.

In his testimony, Mr Gannon said that upon reviewing the footage in the aftermath of the incident, he saw "no violation" of "policy, procedure and law".

"He [Mr Johnson] had a look of fear on his face. It's something I've never seen before," a visibly upset Ms Potter said. "It just went chaotic."
