After September 11, the typical number of deaths from terrorism in a given year was...0, give or take a few, with a disconcerting uptick since 2013. Great, our efforts to curb terrorism are working!
From 1975-2001, the typical number of deaths from terrorism in a given year was...2. Wait, the massive surveillance state has saved 2 lives a year? What? We saved more lives by posting a guard at the Caltrain tracks in Palo Alto to keep people from killing themselves.
By the numbers, terrorism just wasn't a problem, because rational people don't blow themselves up to make a point. Mentally ill people do, and a significant number of mass shootings are not counted in the terrorism statistics but actually kill far more people. But by making terrorism into a big bogeyman that's going to kill you, it feeds into the interests of the media, of the state, and of the military-industrial complex, and so there are a lot of powerful forces shaping the discourse around terrorism that aren't necessarily reflective of reality.
