Ismael Mena, 45, was shot eight times by Denver SWAT officers during a Sept. 29 raid. Officers said they found Mena in a shooting stance, pointing a gun at officers and refusing to lower it. Mena's son, Heriberto Mena, said his father's friends and neighbors think he may have thought he was protecting himself against an intruder. Police and the Denver district attorney's office are investigating. Under the new policy, a police supervisor must now approve all requests for search warrants written by street officers. - --- MAP posted-by: allan wilkinson
