This story takes me back to the horrendously common airliner hijack stories of the 70's. I always wondered why they negotiated and never could put a stop to it.... I learned that there were just about zero hijackings in Japan and I learned why from an ex- Marine who was in Japan for awhile. He was having a drink in an airport and saw some ninja guys go down the tarmac up behind a plane that was stopped part way down the takeoff path, climb in a hatch under the plane, and then proceed to toss bodies out of the plane which took off on time!!
Who cares about some shit that the world can't get the political will to take care of? Who really gives a f%^k anymore, it's about the political will in every single situation... I have friends that would condemn the Japanese government for killing those hijackers because anybody involved in violence is guilty of being violent, whether defending or attacking... with people like that around you can never do anything effective without paying out a lot of political capital.. unless, of course, you never tell anybody!!
