Here's a clue:

In America, you can march down the street in front of news cameras, face in full view, carrying a sign showing the President having sex with a goat.

You can call the president--or ANYBODY in our government, the worst names, or accuse them of the worst actions, in newspapers, on the internet, on YouTube, or on any other public information system. You can do it under your own name, and still sleep peacefully at night, secure that you won't even be threatened by the libel suits that a non-politician could bring to bear, much less be hauled off in the night.

Believe me, people living in real police states are a hell of a lot more quiet.

(BTW, it's likely this entire Rove-Siegelman thing is yet another media pantload. Have you bothered to look at the sources? Start with Jill Simpson.)
