This chapter tests cycles of silence in Lagos to evaluate its applicability in a Global South context where, unlike Baltimore, the state and the police have limited resources. The chapter’s results come from an original survey of shopkeepers, paired with interviews and observation, in the city’s expansive markets, pockets in which “area boy” crews engage in violence and extortion. Consistent with the patterns found in Baltimore, area boy violence reduces cooperation by boosting perceived retaliation risk and making cooperation norms appear to be weaker than they are. Underlying cooperation support exists among shopkeepers, the chapter’s final section explains, in part, because the area boy crews have largely failed to gain legitimacy with Lagosians.
