High levels of violence and conflict in Latin America have attracted the interests of local and international researchers to further understand how to reduce this violence and prevent current and future outbreaks. Conducting research in any environment is challenging. However, the obstacles facing not only researcher safety but also data collection methods are particularly complex in settings with high levels of violence and conflict. This article contributes to the methodological literature, as it provides reflections from two researchers, an insider from the Global South and an outsider from the Global North, each collecting data in Medellín, Colombia. It also argues the importance of collaboration between Global North and Global South researchers investigating violence and insecurity.
