On Tuesday, Michael Slager spoke for the first time as he told the court about his encounter with Walter Scott, whom he fatally shot as a bystander's camera rolled. Slager has been charged with murder and faces 30 years to life in prison if convicted. He alleges he pulled Scott over for a broken taillight. He said the incident escalated when Scott wrestled away his Taser and ran. The video shows Slager opening fire as the unarmed Scott ran away. He was struck multiple times in the back.
