While Colombia experienced a significant boom in tourism in the past decade, the sector has often sprung up in weak legal settings. Medellín is a revealing case. In the country’s second city, tourism is a fast growing business, but public authorities are struggling to regulate it. Medellín is also frequently hailed for its resilience and innovation in international media and in global development programs. Yet, the influence of criminal actors on how it is governed is critical, especially in marginalized neighborhoods. This post offers a brief glance at some of my current research, in which I examine the way intimate relations shape criminal governance. I am interested in how interpersonal ties, like kin, friendship and long-term acquaintances, influence how criminal actors enforce their rules. I explore for instance the extortion of people working in the tourism sector, such as tour guides, street artists and business owners. Through a neighborhood-based approach, I seek to understand some of the micro-dynamics that shape what was often referred to as the rules of the game, in some of Medellin’s marginal areas that began experiencing the arrival of tourists.
