On Oct. 17, 2002, the head of the National Security Agency, Lt. Gen. Michael Hayden, made an eloquent plea to a joint House-Senate inquiry on intelligence for a sober national discussion about whether the line between liberty and security should be shifted after the 9/11 attacks, and if so, precisely how far. He reminded the lawmakers that the rules against his agency's spying on Americans, carefully written decades earlier, were based on protecting fundamental constitutional rights.
If they were to be changed, General Hayden said, "We need to get it right. We have to find the right balance between protecting our security and protecting our liberty." General Hayden spoke of having a "national dialogue" and added: "What I really need you to do is talk to your constituents and find out where the American people want that line between security and liberty to be."
