During the workshop the SELEC Associated Firearms Experts Network (SAFE-N) was presented, a network that is being created under Project SIRAS in order to provide a pool of experts and a platform for direct exchanges among professionals from various fields and environments related to firearms. Project SIRAS aims at strengthening the capacities of the law enforcement agencies in South-East Europe in fighting firearms trafficking. The project envisages to support the use in the EU Member States and the SELEC Member Countries of data collection/analytic capabilities regarding firearms and to strengthen the investigation capacity, as well as joint investigations, police cooperation and standardization between law enforcement authorities in the region.
