The 9/11 Truth Movement is a non-violent effort by thousands (if not tens of thousands) of highly respected professionals in numerous areas of expertise (and potentially millions of other concerned citizens) to demand a legitimate and impartial investigation into the events surrounding the 9/11 attacks. There are countless weaknesses, flaws, and overt misrepresentations in the official account that are painfully obvious to those who actually KNOW something about the Systems and Material science involved in building collapse, as well as the numerous suspicious activities by government and various other domestic groups to suppress and even destroy evidence involved in this crime, for reasons at this point unknown. There are far too many important questions unanswered that can be answered with a legitimate investigation, rather than simply sweep this tragic crime under the rug.
