It's OK if we wiretap Osama bin Laden. I want to know what he's planning - obviously not him nowadays, but that kind of thing. I don't care if it's a pope or a bin Laden. As long as investigators must go to a judge - an independent judge, a real judge, not a secret judge - and make a showing that there's probable cause to issue a warrant, then they can do that. And that's how it should be done.

It's critical how we want to use these spy programs, these electronic capabilities, where we want to draw the line, and who should approve these programs, these decisions, and at what level, for engaging in operations that could lead us as a nation into a war.

That's the key - to maintain the garden of liberty, right? This is a generational thing that we must all do continuously. We only have the rights that we protect. It doesn't matter what we say or think we have. It's not enough to believe in something; it matters what we actually defend.

How do we preserve our civil rights, our traditions as a liberal democracy, in a time when government power is expanding and is more and more difficult to check?
