They're the youngest officers with the most experience. Davis and Bill McDonald started as police officers in Ypsilanti in November, after retiring from jobs with the Washtenaw County Sheriff Department and the Detroit Police Department, respectively. Ypsilanti Police Chief Leonard Supenski believes experience matters, particularly with a young department like Ypsilanti's where veteran officers have retired over the past several years. A lot of what cops do is trainable, but a lot of how they react is from experience on the street.
Money is part of the motivation, but both had options.
Davis worked for the U.S. Customs Service briefly. He didn't like it. I could have stayed at Customs and been unhappy. But I like being a cop. I enjoy getting up to do something I enjoy doing, and have fun at it.
