To tamper with a crime scene is a felony. Whenever an act of arson occurs police representatives would be expected to arrive to quickly service and seal off the area. As anyone schooled in criminal justice realizes, it is imperative to preserve crime scenes intact to assist further investigation and potential criminal prosecution.
In the case of 9/11, we had a series of explosions at the most famous symbol of American capitalism, the World Trade Center. So what was trained prosecutor Giuliani's response, the same Giuliani who was U.S. Attorney for the district embracing New York City, the nation's largest metropolis?
Giuliani brought in Controlled Demolition, the same highly suspect firm which had completed the destruction of the Murtagh Federal Building in Oklahoma City in 1995, disposing of all evidence in the process. The contract that was let just 11 days after 9/11 empowered Controlled Demolition to recycle the steel of the World Trade Center.
As 9/11 official verdict critic Webster Tarpley noted, "Guiliani has not had a word to say about this in his memoirs. The city accepted rock-bottom prices for the steel; the priority was to make it disappear fast."
The steel was transported quickly to China, ending any opportunity to run any tests in connection with ascertaining how the 9/11 explosions may have occurred.
