Officers in homeless Michigan man's shooting get punished One officer gets demoted; two others "disciplined" The incident happened in July and was caught on tape The incident had been caught on video (CNN) -- Three Saginaw, Michigan, police officers involved in the shooting and killing of a homeless man have been punished, a police official said Friday. The on-site supervisor was demoted to patrolman, said Acting Saginaw Police Chief Brian Lipe. Two others were "disciplined," he said, for violating department policies in connection with the shooting. Three of their five dash-cam videocameras were not working properly. No other detail was provided on how the officers were disciplined. The incident occurred July 1. Milton Hall, 49, had been arguing with officers in a parking lot next to a shuttered Chinese restaurant when he was shot multiple times by police, in full view of passing motorists and while he was holding a knife. A video of the incident was exclusively shown in a report by CNN's Jason Carroll weeks later. Six of the eight police officers opened fire, Saginaw County Prosecutor Mike Thomas said earlier this month. All six are remaining on the police force. After a 10-week investigation, police determined that the officers would not face criminal charges because they had not acted with criminal intent when they opened fire, Thomas said. Police responded to a call from a woman at a nearby mini mart before the shooting. She complained that the Hall was rude and aggressive, and had refused to pay for a coffee and other items. She also said Hall spit on someone inside the store. Hall threatened a responding female police officer with a knife. Jewel Hall, the victim's mother, has said that she and her attorney were conducting a separate investigation.
