This chapter features stories about concrete, physical things in cities that enact structural, sociospatial systems and processes of identity-based mass violence. These things occur over time and often out of sight. Except perhaps to the people experiencing them, they may not even register as violence. As a result, if and when these things devolve into crisis for the rest of us, the tipping point can feel like a sudden tragedy, an accident, a disaster. The stories in this chapter—of contaminated water in Flint, Michigan; inequitable access to shade in Phoenix, Arizona; excessive exposure to artificial light in New York; and indifference to the safety of social housing in London—make visible how structural violence is a precondition for atrocity violence. Preventing atrocities, then, demands shifting our gaze “beyond the optical facade of immediate peril” to the structural violence that preceded it.
