Mr Tensing then asks Mr DuBose to unbuckle his seatbelt.
Assistant Prosecutor Seth Tieger presents closing arguments during Raymond Tensing's retrial at the Hamilton County Courthouse in Cincinnati, Monday, June 19, 2017.
During the stop, Tensing asked DuBose, 43, to take off his seat belt, and DuBose is seen turning on the ignition. DuBose said he had not done anything wrong and appeared to turn the auto back on, at which point Tensing drew his gun.
The mayor says the rights of free speech of all people will be supported, including the right to peacefully demonstrate. On Wednesday, a jury acquitted Dominique Heaggan-Brown, a former Milwaukee police officer, on a count of homicide for his fatal shooting of Sylville Smith a year ago, which set off intense protests.
In closing arguments, Tensing's attorney, Stew Mathews, argued that DuBose put Tensing's life in danger when he "elected to start that auto, put it into gear and take off with Ray Tensing's arm trapped inside it".
This comes after a mistrial was also declared when the case was initially brought to court previous year.
DuBose's family said in a statement that they want a new trial and they urged that protests remain peaceful.
A second mistrial has been declared in the Ray Tensing trial after a jury said it could not come to a unanimous decision.
CINCINNATI (AP) - A second mistrial was declared Friday in the case of a white University of Cincinnati officer who killed an unarmed black motorist during a traffic stop.
The 27-year-old Tensing testified he feared he was going to be killed.
Much of the testimony and witnesses were the same in the second trial as in the first.
In May, Tulsa police Officer Betty Shelby was acquitted in the shooting death of Terence Crutcher, an unarmed black man.
USA prosecutors have found it hard to convict police officers in high-profile shooting cases involving black victims - despite recent incidents being captured on video.
"Yes", Deters said. "I think he was making an excuse for the purposeful killing" of Dubose.
Mathews said DuBose had motive to drive away from the traffic stop because he lacked a license and carried a felony amount of marijuana in the vehicle. Perhaps the most striking differences were testimony from Cincinnati Police Sgt. Shannon Heine, who testified in the first trial, and defense video expert Scott Roder who did not.
Jurors in Ray Tensing's murder retrial will get back at it Friday, their fifth day. After five days of deliberations, the mistrial was declared this afternoon.
On Friday morning, after jurors said they were deadlocked on both murder and manslaughter charges, Ghiz sent them back to the deliberating room where, she said, "Hopefully, you're able to resolve your deadlock".
Following the shooting, the University of Cincinnati restructured its public safety department and made other policing reforms.
