Although the notion of universal human rights allows for the idea that states (and supranational organizations such as the European Union) can, or even should, control and impose restrictions on migration, both notions clearly do not sit well together. The ensuing tension manifests itself in our ambivalent attitude towards migration, but also affects the border guards who have to implement national and supranational policies on migration. Little has been written on the ethics that has to guide these border guards in their work. Juxtaposing the ethics of border guarding against the ethics of the somewhat related military profession, this article attempts to (a) describe border guarding as a comparatively rule-guided profession; (b) outline the aim and basis of the ethics education that prepares border guards for their work; and (c) propose a research agenda for the future that should further our understanding of (a) and (b), but also help us improve the moral education of border guards.
