Section 348 takes its title from the Canadian Criminal Code provision addressing "breaking and entering with intent, committing offence, or breaking out." Drawing from photographs produced by the Société de transport de Montréal's security personnel, the book examines bureaucratic images documenting unauthorized entries into Montreal Metro facilities from the 2010s to 2020s. These images capture traces of movement through tunnels, empty stations, maintenance areas, and other restricted spaces rarely seen by the public. Detached from their original function, these photos offer an unusual perspective on the relationship between graffiti writers, transit infrastructure, and the systems tasked with monitoring both.
