That's just what the libs want them to do - shut down books and plays about murdering the president to PROVE that Bush-Ashcroft-Patriot Act are denying people their civil rights.
It would be a lie, of course, but that's clearly the goal of these nimrods. If the Secret Service paid them a visit, you KNOW that will turn into the story and how Bush can't tolerate dissent and how Ashcroft has Nazi storm troopers, etc. - all just in time for the convention.
I say ignore them until the convention is over and then send in the muscle.
I agree, let them have their free speech, and hopefully they will get their "just deserts" by it being the worst play to hit the theater.....just maybe their revenge is noone will hire them if their performance is lousy. So I'm praying it is lousiest performance ever, thereby coming back on their desirability as actors/actresses.
