Ask yourself why the NIST got less than 0.5% of the steel from the towers to analyze.
Since Leo seems to be avoiding this point, I'll discuss it. I still haven't located the 6 points he keeps on about (but this forum search engine keeps spitting out the 6). The word "point" appears to show up all over the place though.
Because proper crime scene protocols were not followed, the investigation was started a month later, and Rudy, PANY, and FEMA shipped much of the evidence off to China for "recycling."
" The BPAT team deployed to the WTC site was assembled by the American Society of Civil Engineers and is headed by W. Gene Corley, Ph.D., P.E, Senior Vice President of Construction Technologies Laboratory in Skokie, Illinois. He was also the principal investigator in the FEMA study of Oklahoma City's Murrah Federal Office Building. On September 11th, ASCE, in partnership with a number of other professional organizations, commenced the formation of an independent team of experts to conduct a building performance assessment study at the WTC site as part of ASCE's Disaster Response Procedure.
In late September, this team, the ASCE Disaster Response team, was officially appointed as the BPAT team and was funded by FEMA to assess the performance of the buildings and report its findings. The BPAT team received $600,000 in FEMA funding in addition to approximately $500,000 in ASCE in-kind contributions.
The 23-member BPAT team conducted an analysis of the wreckage on-site,
at Fresh Kills Landfill and
at the recycling yard from October 7–12, 2001, during which the team extracted samples from the scrap materials and subjected them to laboratory analysis. Why the analysis was conducted only after a delay of three weeks after the attacks remains unclear. Since November, members of the Structural Engineers Association of New York (SEAoNY) have volunteered to work on the BPAT team's behalf and are visiting recycling yards and landfills two to three times a week to watch for pieces of scrap that may provide important clues with regard to the behavior of the buildings.
...
In the month that lapsed between the terrorist attacks and the deployment of the BPAT team, a significant amount of steel debris—including most of the steel from the upper floors—was removed from the rubble pile, cut into smaller sections, and either melted at the recycling plant or shipped out of the U.S. Some of the critical pieces of steel—including the suspension trusses from the top of the towers and the internal support columns—were gone before the first BPAT team member ever reached the site. Fortunately,
an NSF-funded independent researcher, recognizing that valuable evidence was being destroyed, attempted to intervene with the City of New York to save the valuable artifacts, but the city was unwilling to suspend the recycling contract. Ultimately, the researcher appealed directly to the recycling plant, which agreed to provide the researcher, and ultimately the ASCE team and the SEAoNY volunteers, access to the remaining steel and a storage area where they could temporarily store important artifacts for additional analysis.
Despite this agreement, however, many pieces of steel still managed to escape inspection."
That was from the 107th US Congress BTW.

Baosteel of China apparently got the largest contract.
