What facts do you disagree with?
The center existed, it existed on the 23rd floor of building 7, we do not know what caused building 7 to collapes, and that FEMA dismissed that it was the fuel from the two huge tanks that were in the building?
Also housed in there was a then secret CIA operations office and the FBI had an office there too. The state, city, and the feds used the building to store classified data.
How about the fact that he and his administration understated the impact on air quality due to the attacks and that has led to health problems? Or how he extended his own term as mayor? There is plenty on the public record to attack him rather well without resorting to conspiracy theories which, while they may please some, distance moderate voters from the position that he would be bad for the country.
I am not thrilled with him either but compared to some of the conservatives that are tossing their hat into the ring, he would be the lesser or two evils. Hopefully the Dems will field someone that will make most of this a mute argument and we can then start on reversing some of the damage done in recent years.
My inquiry was to prod info out of you.
