Authorities have released body-camera video showing the shooting of a black man by an elderly white reserve sheriff's deputy during a recent arrest in Tulsa, Oklahoma. Authorities say the shooter was 73-year-old Robert Bates, and that he meant to use his stun gun.

The video of the April 2 incident shows a Tulsa County deputy chase and tackle 44-year-old Eric Harris, whom they accuse of trying to sell an illegal gun to an undercover officer.

While the deputy is subduing Harris on the ground, a gunshot rings out and a man says, "Oh, I shot him. I'm sorry."

Harris screams, "He shot me. Oh my God," and a deputy replies, "You fucking ran. Shut the fuck up."

Harris then complains that he is losing his breath, to which a deputy replies, "Fuck your breath.” One of the officers restrains the shot and bleeding Harris with a knee on his head, the video shows.
