Here is a list of evidence showing the basic FEMA deception about the towers core, and the independently verified evidence of the concrete core.
More detail on the FEMA deception is here.
FEMA misrepresented core structure of the Twin Towers.
Any who might be interested in acting to ensure justice with 9-11 can use this information.
THE FEMA "CORE DECEPTION"
Misrepresenting the core structure of the Twin Towers as in the following image.

Further, the truth movement has been mislead by quasi leaders that present helicopter photos showing elevator guide rail support steel and calling it "core columns"
The butt plates on top of the guide rail support steel, left and right of the center crane in this photo of WTC 2 at around the fifth floor show a method of joining far too weak to be used to join core columns.

It is reasonably expected that if no independently verified evidence of steel core columns, or no credible opposition to this information of the concrete core can be made. The concrete core is a fact and what follows independent verification of the fact must lead towards acceptance.
These images and links to independent verifications of the assertion that the images show a steel reinforced, rectangular, tubular concrete core 80x120'. The ones that show pieces, glimpses of the core, show an empty core when shown, and some concrete surrounding it or another feature of the cast concrete structure surrounding the core area.
