Mr Freeman, at a press conference, repeatedly referred to his successful prosecution last year of Mohamed Noor, the Minneapolis police officer who shot dead Ms Damond in an alley behind her home in 2017.
"The Hennepin County Attorney's office is one of the few prosecuting offices in this country in the last five years to successfully prosecute a police officer for murder and we did that on behalf of Justine Damond," Mr Freeman told reporters.
"We know how to do this."
A jury
found Noor guilty last year of third-degree murder and second-degree manslaughter and he is serving a 12.5-year prison sentence.
Mr Freeman announced Mr Chauvin's charges hours after riots broke out in Minneapolis and a police station and other buildings were set on fire.
Protesters demanded Mr Chauvin and three other police officers be charged.
Mr Freeman said the other officers were also being investigated.
"Mohamed Noor was a very difficult case," he said.
"We didn't have the kind of video tape we need and there was all sorts of other evidence that took us a long time."
Murder charges over George Floyd death
Mr Floyd died on Monday after police were called to a Minneapolis shop claiming someone had attempted to use a counterfeit banknote.
Surveillance footage from a nearby cafe showed two officers arriving on the scene and walking to a parked car where Mr Floyd was in the driver's seat.
They put him in handcuffs and took him to their patrol car.
Mobile phone video showed officers kneeling on Mr Floyd on the ground and Mr Floyd pleading he could not breathe.
It was the latest fatal incident involving police and African American men in the Minneapolis-St Paul twin cities. Ms Damond's case flipped that.
Ms Damond, originally from Sydney, was white and Noor was born in Somalia.
Ms Damond, 40, was weeks away from marrying her American fiancé Don Damond on the evening of July 15, 2017.
She was home alone and just before midnight heard a woman's screams coming from an alley behind her house.
Ms Damond called 911 and when Noor's police vehicle pulled up in the dark alley she walked out barefoot and in her pyjamas.
Noor claimed he thought he was being ambushed and, while sitting in his police car, shot across his partner Matthew Harrity and fatally struck Ms Damond in the stomach.
