Bin Laden was behind it apparently, I have theories. Such as where Osama was working with the CIA before hand, there were files that went missing both the day he left and maybe 2,000 top secret files went missing the day before 9/11, They were going to kill him anyways so I think they made a use of him and threatened to kill him and his family to set something up so he could take the blame. But the way that one tower fell is sketchy, it did hold millions of files, maybe they had a bomb put in it during initial construction in case anything happened and the government was hiding something in that building, so they had to make sure it was destroyed? Hmmm
When the current president of Egypt was sworn in back in June, he promised the public he would seek Abdal Rahman's release on humanitarian grounds. At the time our State Dept. stated that it wasn't going to happen. Here is a link to the June New York Times story. It sounds nearly identical to the asker's. Is it a recycled one?
