I disagree. It's not a black and white "protect Fort Knox" or "Don't protect Fort Knox". It's more like saying Fort Knox has never been broken into, so let's evaluate whether we need 240,000 employees to protect it (number of employees in Department of Homeland Security). Let's evaluate whether we need to pat down everyone at an airport to see if they have plans to rob Fort Knox. Let's evaluate whether we need to eavesdrop on everyone on the Internet and record information about their phone calls to see if they're planning on robbing Fort Knox. Let's evaluate whether we need to invade two countries because people from one of those countries actually were able to steal a tiny fraction of a fraction of the gold in Fort Knox.

Our response to terrorism is unique and we treat no other problem like it, going even further than the "war on drugs".
