This would have to be the smallest museum (also free) that I have been to. Worth while visiting, if you’re in Saint John. The entire museum is one small room that’s packed with all sorts of gadgets from the last century. There were a fingerprinting kit, a facial composite sketch kit, badges, IDs, firearms, and an old jail cell door on display. Also a call box, which was a phone hanging on a pole that officers on duty were required use to call in every hour. Let’s not forget, the Volkswagen Police car from 1960s parked on the street right outside the museum.
