Can you prove that the WTC did not collapse by gravity, fires and structural damage?
Your argument is a logical fallacy.. It is known as an
Argument from Ignorance.
What is harder, planting enough high explosives and thermite in 3 WTC buildings? Or manipulating data?
Why do you trust the data provided by government agencies with regard to the Pentagon, yet feel the WTC was destroyed by controlled demolition?
Again, your double standard is astounding.
