Here is another excellent video by Anthony Lawson about 9/11 truth, entitled "9/11: The Unidentified Murder Weapons."
Mr. Lawson wrote:
The four aircraft which crashed on September 11th, 2001 have never been forensically matched to the four passenger planes which were allegedly hijacked that morning. Requests under the Freedom of Information Act have met with denials and refusals, and documents which have been produced, allegedly using data from the only three “Black Box” flight recorders said to have been found, have no serial numbers of the devices listed on them.
The destruction of the jet engines and other parts from the airliners from the World Trade Center, which can be seen in the video, reveals that the mass murder atrocity of 9/11 was never treated as a crime that needed to be investigated. This is why I call the government role the "non-investigation" of 9/11. Why would the F.B.I. and the U.S. Department of Justice allow parts of the airplanes and the steel to be destroyed? Why would Michael Chertoff, then Assistant Attorney of Justice in charge of the criminal section of the Dept. of Justice, permit the wholesale destruction of the evidence from the World Trade Center?
The numbered parts of the jet engines found in the debris would identify the precise airplane involved at each of the four crash sites. Why were they all destroyed? I can think of only one reason - the planes that were involved in the terror attacks of 9/11 were NOT the planes the government says they were. To understand this part of the deception read the second chapter of Solving 9/11 - "The Planes of 9/11"
