In 9/11 Contradictions, David Ray Griffin shows that the official story about 9/11 is riddled with internal contradictions. Two contradictory statements cannot both be true. These contradictions show, therefore, that individuals and agencies articulating the official story of 9/11 have made many false statements. Congress and the press clearly should ask which of the contradictory statements are false and why they were made. This book is purely factual, simply laying out the fact that these internal contradictions exist. As such, the book contains no theory. Politicians and journalists who deal with the issues raised herein, therefore, will not be giving credence to some "conspiracy theory" about 9/11. They will simply be carrying out their duty to ask why the official story about 9/11, arguably the most fateful event of our time, is riddled with so many contradictions.
