Personally I have no doubt that there were Arabs and Muslims in Passaic county who had prior knowledge of the attacks. Something like 26 -30 people have been arrested in Paterson and the surrounding towns. Those people didn't live in a vacuum, and word of mouth in the tight Muslim communities would have disseminated the rumors. The sad part on our security side is,that these people have been here, and privately cheered the 1993 attacks, this time they had the confidence to do so in the streets.
When you remember that they had intentions of killing the President, Congress, wiping out the Pentagon, destroying the economy ----all in a few minutes, it's quite obvious they weren't then going to stop and pack up and go back home. I'm quite sure there were Arabs in every state capitol and major city waiting for Hour 2 for the next level of attacks. Murder governors and state agency heads. There was also indications there were to have been other targets like San Antonio and Atlanta. They meant to throw the US into a chaotic situation with no leaders or military command and then take over. There's no reason to expect that what they do in other places like Sudan and Nigeria isn't what they had in mind for us.
