An Atlanta police officer was charged on Wednesday with murder for the shooting death last week of Rayshard Brooks in a fast-food parking lot, while a fellow officer facing lesser charges has agreed to testify against his colleague.
The death of Brooks - the latest in a long line of unarmed African Americans whose fatal encounters with law enforcement have been documented on video - further heightened U.S. social tensions at a time of national soul-searching over police brutality and racism in the criminal justice system.
