A police officer in Fairfax County, Virginia, is facing possible prison time after using a stun gun on a black man without apparent provocation.

Tyler Timberlake has been charged with three counts of assault and battery for allegedly using excessive force during an arrest that took place on Friday. Chief of Police Col. Edwin Roessler Jr. released body camera footage of the arrest and said the video shows Timberlake acted in a manner that violated the department’s oath of office and ignored the “sanctity of human life.”
