The last time we had a true debate about how the U.S. government should be organized to protect Americans and to protect what it means to be American was almost a quarter century ago. After the attacks of Sept. 11, 2001, politicians sparred over how to balance security and liberty, as if they sat on opposite sides of a scale. Our obsession with security — aided by politicians determined not to appear “weak” and Supreme Court decisions that empowered the presidency — has obliterated that balance. As it has in other countries, the pursuit of security paved the way for the consolidation of power. Now, Minnesota has neither security nor liberty.
