Green Bay has a black police officer for the first time in the 152-year history of its department.
Solomon Ayres starts the first phase of a 17-week training regime this week.
Ayres says he expects some resistance from both black and white residents, but thinks his life experiences will help defuse difficult situations and make him open to different points of view.
Census figures show that African Americans make up about 2.5% of Green Bay's more than 98,000 people.
The department has 177 officers, including 15 women, four American Indians or Alaska natives and one Latino.
