Gregory S. Gordon is an American professor and scholar of international law and former Legal Officer for the Office of the Prosecutor of the ICTR. Gordon is known for his academic work calling for the criminalization under international law of a broader category of speech likely to cause and/or fuel mass atrocities (i.e., broader than mere incitement to genocide), and his book Atrocity Speech Law: Foundation, Fragmentation, Fruition (Oxford University Press 2017) in which he advances this argument.
