You want to fight over land, you seize it. You want to go to war over oil, you grab the other guy’s oilfields. But this is a battle over what people know, and how they come to know it, and whether or not they have the right to know it at all. This is a war on the battlefield of the mind. The rules are different. They have to be. Freedom of thought is not a prize to be won or lost, or even to be contested. It is the natural human right of every person on the planet. We are in an age in which technology has accelerated the processes of exercising that right. The institutions that would abridge that right are slow to catch up. Their efforts are clumsy and, in the case of David Miranda in London, brutal.
