IMO, this kind of thing should be treated the same as someone threatening to do actual physical harm to the president. As in, the men in black need to pay some visits.
Oh, won't the media be orgasmic if they perform this stunt.
That's rediculous.
You would have been cheering had it been Clinton.
They can rip up pictures of Bush, piss on them, topple statues, beat a Bush pinata, etc. That's free speech.
And it's my free speech to laugh at them and mock their obvious stupidity and powerlessness.
