Glen Greenwald reports that when the Chinese government sought out the murderer of 13 Chinese citizens, the use of drones was not an option:

What kind of weak, soft, overly legalistic government worries about trivial concerns like international law and “sovereignty issues” when it comes to drone-killing heinous murderers for whom capture is difficult? Why not just shoot Hellfire missiles wherever you think he might be hiding in weaker countries and kill him and anyone who happens to be near him? Or if you are able to find him, at least just riddle his skull with bullets, dump his corpse into the ocean, and then chant nationalistic slogans in the street and at your political conventions. Who would ever want to give a trial to such a heinous and savage foreign killer of your citizens, particularly if it means risking the lives of your soldiers to apprehend him? What China did instead was conduct what the NYT this morning calls a “methodical and unyielding” law enforcement investigation over the course of six months.
