Did anyone but the Press hear the "Kill HIm" comment?

Michelle Malkin is following the strange story of the Liberal Press who wet themselves at the report that someone in the crowd of a Palin event in Scranton PA. yelled "Kill him" when Obama was mentioned.

However, there were Secret Service agents there, both on her detail, and in the crowd, and not one of them heard it. So they asked others who were there, and they didn't hear it. 

I wonder if this report is another of the Phony Hate Crimes that we've all grown too accustomed to from the Liberals.

Why is it that Liberals have so much trouble with things like truth, and facts?
