weird guy.
Anyways, yeah GG has killed Jedi but only with possibly one saber or blasters. Take in mind that even if GG had that saber he would not be skilled with it and he is a brilliant strategist but that may not help him kill a Jedi Master (and a decent duelist) in single combat, and yes, AOTC GG has killed Jedi but they were most probably practioners of Niman, and therefore not particuarly ahrd to kill...
