Bruce Schneier has a modest proposal:
Securing the Washington Monument from terrorism has turned out to be a surprisingly difficult job. The concrete fence around the building protects it from attacking vehicles, but there's no visually appealing way to house the airport-level security mechanisms the National Park Service has decided are a must for visitors. It is considering several options, but I think we should close the monument entirely. Let it stand, empty and inaccessible, as a monument to our fears.
An empty Washington Monument would serve as a constant reminder to those on Capitol Hill that they are afraid of the terrorists and what they could do. They're afraid that by speaking honestly about the impossibility of attaining absolute security or the inevitability of terrorism -- or that some American ideals are worth maintaining even in the face of adversity -- they will be branded as "soft on terror." And they're afraid that Americans would vote them out of office if another attack occurred. Perhaps they're right, but what has happened to leaders who aren't afraid? What has happened to "the only thing we have to fear is fear itself"?
An empty Washington Monument would symbolize our lawmakers' inability to take that kind of stand -- and their inability to truly lead.
I like Bruce's attitude. We have to have someone in political leadership prepared to say that at some point a free society will have to tolerate some level of terror. Or cease being free.
