From Glenn Greenwald:
The Constitution is grounded in the premise that there are other values and priorities more important than mere Safety. Even though they knew that doing so would help murderers and other dangerous and vile criminals evade capture, the Framers banned the Government from searching homes without probable cause, prohibited compelled self-incrimination, double jeopardy and convictions based on hearsay, and outlawed cruel and unusual punishment. That’s because certain values — privacy, due process, limiting the potential for abuse of government power — were more important than mere survival and safety. A central calculation of the Constitution was that we insist upon privacy, liberty and restraints on government power even when doing so means we live with less safety and a heightened risk of danger and death.
