and who was in charge of security at the WTC ? It is possible that this was allowed to happen but in spite of my avatar I don't believe all theories. I've read a lot of theories about this and although some of them are sort of possible they would have involved so many people that some valid info would have leaked out. I question why Osama was not hunted down and killed or captured. We gave billions to Pakistan with no material results until President Obama put their feet to the fire. Unfortunately the weed that is Al Qaeda had time to grow long roots.
