Its been known that the government knew the attacks were coming, they just didnt know where to start.  For example, ive read in some reports that the airports knew the planes had been hijacked ect ect. no clue if its true or not but the 9/11 attacks were good in another matter in which they finally are making americans realize that they arent that great or invisible. im american and i cant stand how stubbern alot of americans can be when it comes to that stuff
