After hearing that the Madison Police Department was going to expand the bike policing program by tripling its bike fleet and instituting a formal training program, I got curious. What exactly do these men and women do? So I asked to tag along for a Saturday night shift….Within minutes, it’s quiet no more. In the next hour and a half, the officers flush a guy hiding in downtown backyards into the waiting arms of a patrol officer, send a State Street scam artist packing, and break up a gathering of drinkers at “Concrete Park,” which involves an angry dog, lots of citations and a trip to the hospital for Fiore.
