While poking around the web looking for information on “free-speech zones” (trying to figure out how on earth they pass muster under the First Amendment), I happened upon numerous references to this:
In May of 2003, the Department of Homeland Security issued a terrorist advisory to local police departments warning them to be on the lookout for people who “expressed dislike of attitudes and decisions of the US government.”
There doesn’t seem to have been any mention of this advisory from the major media outlets. On the one hand, I haven’t seen the advisory (I’ll see if I can track down a copy). On the other, it does seem consistent with the Bush administration’s approach to the freedom of speech.
