Kenosha, Wis. (AP) — A Wisconsin prosecutor has declined to file criminal charges against a white police officer who shot a Black man in the back last summer. Kenosha County District Attorney Michael Graveley said Tuesday that he had decided not to charge Officer Rusten Sheskey and other officers, saying he didn’t think he could prove Sheskey and other officers weren’t acting in self-defense. Sheskey shot Jacob Blake in the back after responding to a domestic dispute on Aug. 23. Cellphone video shows Blake walking away from officers and opening the door of an SUV moments before Sheskey opened fire. The shooting left Blake paralyzed and triggered several nights of protests in Kenosha, with some turning violent.
