However, I do not understand how that implicates the owner in any wrongdoing. Interestingly one prominent website, 9/11 Research which is highly critical of the official explanation, is not convinced either and thinks it might even be "bait" to discredit the truth movement. The crucial words seem to be "pull it" and Larry Silverstein's spokesman provides an explanation: "Mr Silverstein expressed his view that the most important thing was to protect the safety of those fire fighters, including, if necessary, to have them withdraw from the building." I talked to the man who assumed command of the New York Fire Department that day. Chief Daniel Nigro told me that it was his decision to decide what to do about Tower 7. In other words there is no way Larry Silverstein could have ordered the fire department to leave the building and wait for it to be demolished. As Chief Nigro told me the fire service was not part of conspiracy, they were doing their job: "When we are in charge of a building, we are in charge and that decision will be the fire chiefs and his alone...That's why I know there is no conspiracy, because for me to be part of that would be obscene and it disgusts me to even think of it."
