"Where Should Airport Security Begin?"
In this essay, Clark Ervin argues that airport security should begin at the front door to the airport:
Like many people, I spend a lot of time in airport terminals, and I often think that they must be an awfully appealing target to terrorists. The largest airports have huge terminals teeming with thousands of passengers on any given day. They serve as conspicuous symbols of American consumerism, with McDonald’s restaurants, Starbucks coffee shops and Disney toy stores. While airport screeners do only a so-so job of checking for guns, knives and bombs at checkpoints, there’s no checking for weapons before checkpoints. So if the intention isn’t to carry out an attack once on board a plane, but instead to carry out an attack on the airport itself by killing people inside it, there’s nothing to stop a terrorist from doing so.
To prevent smaller attacks—and larger ones that could be catastrophic—what if we moved the screening checkpoints from the interior of airports to the entrance? The sooner we screen passengers’ and visitors’ persons and baggage (both checked and carry-on) for guns, knives and explosives, the sooner we can detect those weapons and prevent them from being used to sow destruction.
This is a silly argument, one that any regular reader of this blog should be able to counter. If you’re worried about explosions on the ground, any place you put security checkpoints is arbitrary. The point of airport security is to prevent terrorism on the airplanes, because airplane terrorism is a more serious problem than conventional bombs blowing up in crowded buildings. (Four reasons. First, airlines are often national symbols. Second, airplanes often fly to dangerous countries. Third, for whatever reason, airplanes are a preferred terrorist target. And fourth, the particular failure mode of airplanes means that even a small bomb can kill everyone on board. That same bomb in an airport means that a few people die and many more get injured.) And most airport security measures aren’t effective.
His bias betrays itself primary through this quote:
Like many people, I spend a lot of time in airport terminals, and I often think that they must be an awfully appealing target to terrorists.
If he spent a lot of time in shopping malls, he would probably think they must be awfully appealing targets as well. They also “serve as conspicuous symbols of American consumerism, with McDonald’s restaurants, Starbucks coffee shops and Disney toy stores.” He sounds like he’s just scared.
Face it, there are far too many targets. Stop trying to defend against the tactic, and instead try to defend against terrorism. Airport security is the last line of defense, and not a very good one at that. Real security happens long before anyone gets to an airport, a shopping mall, or wherever.
