Mr Zappa, I am astounded at the courtesy and soft voiced nature of the comments of my friend, the Senator from Tennessee. I can only say that I find your statement to be boorish, incredibly and insensitively insulting to the people who were here previously, that you could manage to give the First Amendment of the Constitution of the United States a bad name, if I felt you had the slightest understanding of it, which I do not. -- - Senator Slade Gorton
