New 'Prowl' Cars on Dress Parade: Parked in neat echelon alongside the city hall are six new police patrol cars grouped on display for the first time since their delivery to the Ann Arbor police department. Officers pausing for a photograph after completing an inspection of the new machines are, left to right: Capt. Rolland Gainsley, head of the police traffic division; Police Chief Casper Enkemann; and Capt. Albert Heusel, head of the police detective bureau.
