Some Muslim told me that this book proves the attack to be a conspiracy against Islam. Examining Davidsson's claims confirmed that there is no genuine evidence against the claim that 9/11 was carried out by Arabs sent by Al-Qaeda. The book grossly misquotes and misrepresents sources - and puts sources which have no relation to the government or witnesses - to muddy the water. Sometimes the book makes clearly false claims like hijackers surviving or that cell phone calls are impossible at higher altitudes. In short, the author Davidson has actually counterfeited evidence to frame the U.S. government for the events of 9/11 and acquit Al-Qaeda which was clearly resposible. I wish I could give minus infinity. Please don't waste time on this liar.
