    We all know of market manipulation, like the story of the high school kid spamming stocks to Yahoo message boards [1], but what of competitor, - industry - or country manipulation?…

    The one who ordered the drone strike is responsible (but hardly held responsible). Easy to draw the parallel with ordering the deployment of anti-personel landmines: the one who or…
