The death of a black man shot in the back while fleeing a white police officer was the act of a racist cop, a minister has told hundreds of mourners at the funeral of Walter Scott.
"All of us have seen the video," the Reverend George Hamilton, the minister at WORD Ministries Christian Centre, told the congregation.
"There is no doubt in my mind and I feel that Walter's death was motivated by racial prejudice."
Authorities have not said whether race was a factor in the shooting.
Scott was a father of four and Coast Guard veteran whose death sparked outrage as another instance of a white law officer fatally shooting an unarmed black man under questionable circumstances.
The shooting last weekend in North Charleston was captured on a dramatic mobile phone camera video by a man who was walking past.
About 450 people gathered in the church where Scott had worshipped.
About 200 more people waited outside beneath the portico of the church or under umbrellas in the rain because the sanctuary had reached capacity.
Hamilton called Michael Slager - the officer involved in the shooting and who has been charged with murder and fired - a disgrace to the North Charleston Police Department.
"This particular cop was a racist. You don't Tase a man and then shoot," the minister said.
But he added "we will not indict the entire law enforcement community for the act of one racist".
Scott was driving a 1991 Mercedes and police said he had a broken tail light.
Video from the police car's dashboard camera shows Slager asking Scott for his licence and registration, then heading back to his cruiser before Scott gets out of the car and runs.
Scott's relatives suspect he fled out of fear of being jailed again over missed child support payments.
He owed more than $US18,000 ($A23,403) in child support and court fees, according to Charleston County records.
