This chapter begins conceptualizing the relational dynamics of collusion, outlining the resources, practices, and processes that sustain the clandestine relationships between police officers and drug market participants. The identification and description of these resources, practices, and processes underscore both the negotiated and provisional character of the clandestine interpersonal transactions, their impact on daily violence, and the ambivalent character of state action. The chapter reconstructs the case of Los Monos, an infamous drug market organization that relies on its contacts with police to navigate its competition, engage in retaliation, and direct its use of violence.
