Just finished reading it last month.
Very, very important subject.
David Ray Griffin is a scholar of scholars. His books seem to have as many pages of endnotes, documentations, and citations...as the pages of his actually narrative.
Reading right now Griffin's "The New Pearl Harbor Revisited". A damning, again meticulously documented, back-story of the events of 9/11 and the ensuing cover-ups.
Time to INVESTIGATE the investigators of 9/11. PROSECUTE the prosecutors. EXPOSE the cover-up.
