This MPT presents a project investigating ways in which a given state can provide formal protection for marginalized populations at risk. The case selected is the street sex industry in Switzerland. Here, I present how I attempt to answer the research question Within the context of differing regulatory frameworks in Swiss cities, are there effective formal protection mechanisms in place for decreasing the risk of violence for street sex workers, and do those affect the behavior of street sex workers? through a combination of ethnographic research and a model. I discuss relevant literature related to protection rackets, police, and sex work. Additionally, a miniature case study is included to connected the outlined theoretical definitions and concepts to empirical data."
