Why was a 61 year old librarian thrown out of mccain's town hall meeting?

Same reason that Hispanic lady was thrown out because of her sign. If McCain doesn't like it he completely gets rid of it. And let me state this before anyone trys to use it. Obama's security didn't throw that Islamic lady out of the building they put her in a different seat. I think it was still inexcusable to do so,but it is a hell of a lot better than being thrown out completely.
