61-year-old librarian removed from out side McCain Town Hall

This story in from Denver, outside a John McCain town hall event. A 61-year-old librarian was holding a sign that read Bush=McCain outside the venue where John McCain was holding a town hall and she was approached by police and Secret Service and told she had to leave or she would be arrested. She was not causing any disturbance and she was OUTSIDE the venue. And you thought we had free speech in this country. Joe Knollenberg has endorsed John McCain. I wonder if he endorses this kind of abridgment of free speech rights.
