Two recent shootings involving white law enforcement officers who killed black men — one in South Carolina and one in Oklahoma — have re-ignited the debate over the use of deadly force and race relations in the U.S.
Here is a look at those cases.
The man in the car with Walter Scott before he was shot while running away from a white officer during a traffic stop said he doesn't know why his friend ran - but that he didn't deserve to die.
Pierre D. Fulton released a statement this week through his lawyer, Mark A. Peper. Fulton called Scott a dear friend and asked for prayers for Scott's family. Fulton also asked for privacy moving forward, and his lawyer said he would not comment further until any court proceedings get underway.
"I'll never know why he ran, but I know he didn't deserve to die," Fulton said in the brief remarks.
The shooting was captured on a cellphone video recorded by an eyewitness who was walking nearby. The footage shows Officer Michael Slager, who is white, firing eight times as Scott, who was black, runs. Scott then falls to the ground.
Video from the dashboard of a police cruiser captured Slager telling someone in a phone call that Scott had tried to grab his Taser. The attorney who represented him immediately after the shooting also said Scott had reached for the officer's Taser.
Slager was charged with murder days later, immediately after the cellphone video surfaced showing the officer shooting at Scott as he ran away.
A 73-year-old reserve deputy turned himself in on and was booked into the county jail on a manslaughter charge after authorities said he confused his stun gun and handgun and shot a suspect subdued on the ground, the deputy's attorney said.
Robert Bates could face up to four years in prison if convicted of second-degree manslaughter. Bates was released after posting bond.
A video of the incident recorded by a deputy with a sunglass camera shows a deputy chase and tackle Eric Harris, 44, who authorities said tried to sell an illegal gun to an undercover officer.
A gunshot rang out as the deputy wrestled with Harris on the ground, and a man says: "Oh, I shot him. I'm sorry."
Harris' family blasted the way deputies treated Harris after he was shot, saying in a statement that he was treated as "less than human."
Harris' brother, Andre Harris, has said he does not believe the shooting was racially motivated.
