Police officer under investigation for punching tased drunk man on ground.

Missouri police officers are being investigated for their use of force after a video surfaced of them punching and tasing a drunk man outside a bar in Columbia. The man repeatedly asked the officers to explain what was happening as he was pinned down and maced. The officers then tased him twice and punched him in the face, causing him to bleed. It is unclear why the man was being arrested, and the officers' current status is unknown. The Columbia Police Chief has requested an independent criminal investigation into the incident.
