Almost certainly....Mister Grassy Knoll has spoken.
Christopher Hitchens has locked horns with Blumenthal in the past, love to see his take on this.
Christopher does have a way with words.
"Mister Grassy Knoll" is a nickname for Sidney Blumenthal that he has had for years. Personally I doubt Blumenthal believes the stuff he writes and does it for propaganda purposes and financial gain.
