There are currently 1600+ verified architects and engineers (ae911truth.org) that have conducted an independent investigation into the total collapses of the World Trade Center Towers 1 and 2 and Building 7. These professionals have concluded that the 3 structures were intentionally destroyed by a combination of explosives/incendiaries in a controlled manner.
In order to uphold and advance the integrity, honor and dignity of the architectural/engineering profession, and to protect the public, a criminal investigation must be conducted to determine why the National Institute for Standards and Technology issued fraudulent and unscientific reports regarding all 3 WTC collapses and also to determine why they are withholding data that has been requested under the Freedom of Information Act.
