Tactics Institute opens our series on Europol engaging in a discussion with an interview with Professor Bill Tupman, advisor to police forces worldwide and a point of reference in academic research on transnational crime, terrorism and the process of creating a supranational police response to these phenomena. Professor Tupman explains why not taking the lead in the pan-European Task forces is not a problem for the British police and expands on the practical issues that may arise, including data-sharing, intelligence sharing, prosecution, and investigation in the post-Brexit world.
