A strong national defense is vital in a post-9/11 world. That includes comprehensive border security. In keeping us safe, the government may be tempted to overreach in ways disturbing to those of us who value our liberty above all else. Spying on Americans in the name of security is unacceptable. Finding the right balance between our national security and our freedoms is essential in keeping Americans safe from terrorists who want to kill us because they hate our way of life.
