This is the same news industry that kept quiet long enough for Dubya to launch the illegal war in Iraq, and then obediently clapped its flippers and proclaimed "Je suis Charlie!" when it suited the war on terror propaganda. Once the military-industrial complex starts beating anew the drums of war, these hacks will be back to saying "Charlie? Qui est-ce?", and forget about "freedom of the press" all over again.
