Bobert:

What specifically did the sign say?

I would like to see it my self so I an make my own determinations. That is what you call questioning, critical thinking.

I saw one at a anti-bush rally that said "I am here to kill Bush, shoot me"

Was the person either arrested or shot?

You seem so tormented by these misconceptions of yours.

I see no evidence of this "screaming for re****ks to kill Obama" either real or otherwise.

And why is this undetected screaming directed at re****ks?

Here's scream: "kill all the rich people, break up their cars and apartments, bring the revolution home, kill your parents, that's where it's at."
