After every major terrorist attack in any part of the world, security officials and the American public alike turn to the question of what can be done to deter or prevent a similar attack from occurring here. Unfortunately, it often requires a major disaster to arouse concern sufficiently to mobilize the political will to take needed action. Useful things are often accomplished in the shadow of tragedy. It is not because those charged with security are unable to imagine what terrorists might do. It is rather that people seldom support costly and potentially disruptive measures to protect them against things that haven't occurred. The reality is that because terrorists can attack anything, anywhere, any time, while we cannot protect everything, everywhere, all the time, security, tends to be reactive. Certainly we must try to protect targets that terrorists show a proclivity to attack. |
