Project Interknow is the UK National Response to the emerging threat of privately manufactured and 3D Printed Firearms.  A joint enterprise between Counter Terrorism Policing (CTP), widely acknowledged for their innovative work in this area and the National Crime Agency (NCA), which leads the national response to the threat from the criminal use of firearms.  The event will involve guest speakers from EUROPOL, ATF, Dutch Police, Kings College London & Armament Research Services (ARES), covering the history of 3D printed firearms from the Liberator to current models.  CTP and the NCA will also outline the threat, detailing case studies, investigative opportunities and intelligence requirements to enhance Law Enforcement and Private Industry’s collective response.
