I don't see how you can honestly watch Blueprint for Truth, like honestly watch it without instantly discarding the info, and not think twice about 9/11. Simple physics that a 10 year old can grasp which show the 3 towers were brought down via controlled demolition.
How do you explain the fact that the buildings fell at free-fall speed, not just for a split second either. They also fell symmetrically straight down into their own footprint (except of course for the top section of the tower that fell sideways hitting wtc7, but still had enough downward force to cause the lower 80% of the building to fall symmetrically at free fall speeds, and causing horrible fires that eventually brought the wtc7 building down symmetrically at free fall speeds.
Then theres the visual evidence including squibs coming from the bands you can see around the building which just happen to be the most heavily reinforced parts of the towers (the towers are 3 buildings stacked ontop of eachother. The joint, aka sky-lobby, must obviously bear a very heavy load.

Honestly though you can't argue the points made in Blueprint for Truth. Then once it finally dawns on you non-truthers that 9/11 was controlled by the US federal government and military, you will look into other political conspiracy theories from ages ago and realize not only is it highly possible for a secret society to be in control or planning to become in control, but that there has been for much longer than one may think and they have been slowly, with the world their stage, enacting their script. Many people have been murdered for speaking out against secret societies and warning of the potential they have to gain full control.
