Graffiti is often categorized by municipal authorities as a symptom of 'broken windows'—a sign of neglect that invites further criminality. However, from a sociological perspective, unauthorized street art can be seen as a reclamation of agency in a city dominated by corporate advertising. If the visual landscape of the city is for sale to the highest bidder, the citizen without capital is effectively silenced. In this context, the tag or the mural is an assertion of existence. It is a refusal to allow the city’s walls to be merely a monologue of consumption. By treating graffiti exclusively as a nuisance, we ignore the underlying plea for visibility from those the formal economy has rendered invisible.
