In New York, a State Supreme Court judge has convicted an undercover police officer of negligent homicide in the killing of an African immigrant two years ago. The officer, Bryan Conroy, shot the unarmed Ousmane Zongo during a raid on a CD duplication plant inside a Manhattan warehouse. Zongo, who spoke little English, was in the warehouse working on restoring African artifacts. The officer faces up to four years in prison. Conroy could have faced a 15-year prison term but the judge cleared him of second-degree manslaughter. Meanwhile on Saturday protests were held across the country to mark the 10th annual National Day of Protest Against Police Brutality.
