An inside job? Clinton retorted, with indignation in his voice. How dare you. How dare you! It was NOT an inside job!
And to the person so cynical about America as to assert that our nations government perpetrated the terrorist attacks on its own people, Clintons message was quite clear indeed: dont you dare say such things about our country My Presidency.
Reading this article, it sounds more to me like Mr. Bill was indignant at the gall of this unwashed heckler to show anything but the standard genuflecting behavior he and his little cookie-baking missuz have grown so fond of.
Not to worry, though, the bowing and scraping done by the writer of the article made up for that.
(...and no, I am not defending in any way the comments made by the heckler)
You are right on the money. Everything is all about him.
