Abstract
This article presents a case study in how sellers of weaponizable technology can develop safeguards to mitigate risks of misuse by end users. In 2020, the authors were approached by a defense technology start-up whose core product offering was weaponizable drones. The start-up sought guidance in designing terms of sale and service that would ensure responsible usage of this technology. Combining elements from just war theory, international humanitarian law, and the theory of responsibility, we developed a novel, systematic framework for reducing risks of misuse on the basis of precise principles and objective metrics. Although designed for a specific use case, we believe aspects of this framework are portable to a wide range of scenarios. We share it to demonstrate proof of concept and stimulate further work on integrating ethical considerations into the business of weapons and dual-use technology.
