Bruce Schneier has an excellent piece (Slouching toward Big Brother) in news.com about how we are gradually letting our civil liberties slip away without a whole lot of discussion.
Reminds me of the story about boiling a frog: if you drop a live frog in boiling water, it will leap out immediately. But if you drop a frog in tepid water and gradually turn up the heat, it won't notice and will eventually be frog soup. I don't know if that story is true, but it's certainly apocryphal.
That's what Bruce argues is happening to us. We're the frog, by the way.
This is also related to the point I just made about the tax cut debate, or lack thereof: we seem to have been doing a lot of things in this country since September 11th without a whole lot of discussion. That's understandable, but it's not right.
