One moment, a man reaches into his vehicle after a South Carolina trooper asked for his driver's license.

Seconds later, the trooper shoots him, and the man asks why. Days afterward, prosecutors aren't satisfied with the answer.

Authorities released dash-camera video Wednesday showing what they say is Sean Groubert, a decorated South Carolina Highway Patrol trooper, shooting Levar Jones, who was unarmed, in the parking lot of a gas station just outside Columbia on September 4.
