The point of terrorism is not to "destroy." It is to terrify. And for eight and a half years now, the dominant federal government response to terrorist threats and attacks has been to magnify their harm by increasing a mood of fear and intimidation. That is the real case against the ludicrous "orange threat level" announcements we hear every three minutes at the airport. It's not just that they're pointless, uninformative, and insulting to our collective intelligence; it's that their larger effect is to make people feel frightened rather than brave.
