The following video is an excellent example of how the U.S. government investigation of 9-11 was actually an intentional "non-investigation" that refused to take into consideration any of the evidence of Thermite and explosives that were evidently involved in the demolition of the World Trade Center. The NIST official in this video, Dr. John L. Gross, is clearly complicit in the government cover-up of 9-11.
Dr. John L. Gross is a research structural engineer at the National Institute of Standards and Technology (NIST).
Dr. John L. Gross was awarded the Department of Commerce Gold Medal in 2005 and Special Act Award in 2008 for his role in the “non-investigation” of the collapses of the Twin Towers, an act of explosive demolition which took nearly three thousand lives.
According to his webpage at NIST, Dr. Gross can be reached at (301) 975-6068 or by email at email@example.com
