If there were any “secondary explosive devices” in the Twin Towers on 9/11/01 al Qaeda probably put them there.

What I find interesting about the “secondary explosives” in the WTC issue is that everyone on both sides of the “inside job” issue seems to automatically link “secondary explosives” with “inside job”. An Al Qaeda linked cell put a bomb in the parking garage of the WTC in 1993 and that bomb builder is the same Ramzi Yousef who conceived of flying planes into targets in the USA and his uncle is “9/11 mastermind” Khalid Sheikh Mohammed. They are both engineers and Yousef was a master bomb builder. They both had many supporters among the Islamic extremist community in New York City surrounding the convicted terrorist Sheikh Omar Abdel Rahman and they both likely had WTC blueprints courtesy of one Amin Refai, a certain jihad supporting companion of “The Blind Sheikh” Rahman who also happened to be an accountant for the FDNY who stole WTC blueprints.
