Researching illegal activities, while an object of increasing interest, generates a range of methodological challenges for political scientists. Rather than an exhaustive discussion, this article provides a simple framework that structures these challenges. It highlights that illegality itself is an insufficient guide to method development and needs to be supplemented by an analysis of three further dimensions: enforcement, normalisation and ethics. The article notes that beyond providing insights into the feasibility and challenges of different methodologies, examining these dimensions also directly point researchers to key political science questions about illegal activities themselves.
