TUCSON, AZ (Tucson News Now) - Three months after police and basketball fans clashed in Main Gate Square and cell phone video of a Tucson police sergeant knocking down a woman who appeared to pose no threat to him went viral, body cam video from the sergeant's perspective is now available. Tucson Police released 20 more hours of body cam video Wednesday to include that from Sergeant Joel Mann. Two incidents that police consider inappropriate uses of force can be seen.
