In Oklahoma, a former volunteer sheriff’s deputy who fatally shot an unarmed African-American man while the man was restrained has been sentenced to four years in prison. Robert Bates claimed he mistook his gun for a Taser when he fatally shot Eric Harris last April. An internal report from 2009 revealed how Bates, a wealthy donor to the sheriff’s office, had been allowed to flout policies, patrolling in his own vehicle and conducting traffic stops on his own without adequate training.
