On Thursday, Tulsa County District Attorney Steve Kunzweiler charged Shelby with first-degree manslaughter. She was released after posting bond.
If convicted, she faces at least four years in prison, lawyers said.
Demonstrators in Oklahoma marched to the Tulsa County courthouse and rallied on Saturday afternoon before a funeral for the unarmed black man who was fatally shot by a white police officer after his vehicle broke down and blocked a road.
Solomon-Simmons feared that he, too, could have been killed like Crutcher.
They released the videos, one of which was taken from a police helicopter and the other from a dashboard camera in a patrol auto, in a bid for transparency. "At that point, Mr. Crutcher began walking towards the abandoned vehicle with his hands held up and was not responding to any of Officer Shelby's commands to stop", the affidavit claims.
Terence Crutcher was remembered Saturday evening at Antioch Baptist Church.
He told that crowd that 'it could have been me, ' before reciting the names of black residents who died after police encounters nationwide in recent years.
"Terence will be greatly missed because he was loved", Woodard said.
Tulsa Mayor Dewey Bartlett also attended the service.
Darren Rovell of ESPN reports poll results gathered and shared by E-Poll Marketing Research last week shows 29 percent of 1,100 Americans polled say they "dislike" Kaepernick the most.
Crutcher's death on September 16 and the fatal shooting of a black man 4 days later by a police officer in Charlotte, North Carolina, are two of the latest police-involved shootings to fuel anger over police brutality against African Americans.
"I say that this was the shot that was heard around the world", Armstrong said.
