The police chief of a Milwaukee suburb that has seen protests and unrest since an officer was cleared of criminal wrongdoing in the fatal shooting of a Black teenager in February said Monday that he sees no reason why the officer should be fired. Joseph Mensah, who is also Black, fatally shot 17-year-old Alvin Cole on Feb. 2 outside the Mayfair Mall in Wauwatosa. Milwaukee County’s district attorney announced last week that like the first two fatal shootings, Mensah would not be charged in Cole’s death.
