Lead is too narrow  The lead states Adherents of the  Truth Movement deny that alQaeda terrorists hijacked four airliners and intentionally crashed two into the World Trade Center buildings I think this is too specific as not all proponents argue this Some engineers particularly only claim that the towers were brought down with the help of explosives without any assumptions as to who was involved The use of explosives doesnt preclude AlQaeda or anyone else from hijacking or otherwise airliners or aircraft of similar description from intentionally crashing into the WTC It seems fairly obvious that aircraft flew into the buildings but that also doesnt preclude the use of explosives Im not a die hard truther but I dont belive the mainstream media or the US government either As a structural engineer there does seem to be some quirks in the hypothesis put forward by NIST and the apparent hasty destruction of material evidence from the disaster does seem very questionable Calling for further investigation doesnt seem unreasonable regardless of what actually happened There seems to be a lot of people who get offended even by the mere suggestion of further investigation which may in fact help to clear the government of any involvement I guess these people who seem to get all their facts from Fox and CNN explain why the US government is able to get away with gradual erosion of liberties PATRIOT NDAA TSA etc Ignorance must surely be bliss for these morons Goodbye ye olde land of the free and the home of the brave
