A Wisconsin appeals court says Milwaukee officials properly fired a white police officer who shot and killed a black man.Former Officer Christopher Manney found Dontre Hamilton lying on the ground in a downtown park in 2014. Manney shot Hamilton after Hamilton grabbed his baton during a pat-down search. Manney wasn't charged, but Chief Ed Flynn fired him for violating department pat-down policies. The city's Police and Fire Commission upheld the firing. A Milwaukee judge ruled the termination was proper, but Manney argued to the 1st District Court of Appeals that the department's pat-down policies are vague, and his due process rights were violated. The court rejected his arguments Tuesday, saying the commission acted properly.
