"If I recall correctly, he wasn't arrested for his 'speech' per se, he was arrested when he refused to leave after being asked to leave."
Haven't heard that one yet. Do you have a source? If he really was arrested for refusing to leave, then this whole discussion is moot.
There is a link to the incident report in post #15. Disorderly conduct.
The original articles as well as several post threads here made this point. I'm fairly new to FR, so I'm not sure how to pull up those old posts and threads, or I would post them.
Sorry. I don't have time right now to look into it myself- got things to do, but you might look the original Drudge post, for example...
