To know, within an hour or two of an event, that someone is safe: It’s so valuable, so emotionally practical, as to be almost priceless. It is anti-terror, in a way: It says, be not afraid. And in the three places where it was first deployed—Afghanistan, Chile, and Nepal, all three after major earthquakes—its activation made a lot of sense, because earthquakes are events which by their nature can affect millions over huge swaths of territory.
But earthquakes and cyclones are not themselves public-facing events. Terrorist attacks are. As Brian Jenkins, a terrorism scholar at the RAND Corporation, writes, “terrorism is aimed at the people watching.” Terrorism is a public-relations campaign with guns and bombs. It weaponizes culture, and it exploits journalistic concern for heinous violence to grab media attention and get pathology taken instead as politics.
