NIST Lead Engineer Questioned About 9/11 ~ Denies Molten Metal

This video shows John Gross, the NSIT Lead Engineer, lying about the molten metal around the WTC site. Under his lies are pictures and videos of the glowing or melted metal.

This makes me think the people on the 9/11 commission were not innocents who were lied to but people chosen to lie and cover up what really happened.
