A South Carolina deputy wept with remorse after mistakenly shooting a 70-year-old man during a traffic stop because he thought the man’s cane was a shotgun, a grim new video shows. York County Deputy Terrance Knox fired several shots at elderly motorist Bobby Canipe during a traffic stop on Feb. 25 after the old-timer got out of his truck to retrieve his cane from the flatbed. In video released by York County Sheriff Bruce Bryant Wednesday, Knox yells “sir” and then “hey” several times before opening fire. Canipe was hit once and is expected to recover. Knox pulled Canipe’s truck over because his license plates were expired.
