This poster issued by the FBI, although revised in November 2001, does not say that Osama bin Laden was wanted in connection to the 9-11 attacks. It only specifically mentions the African Embassy Bombings from 1998. Why? Because, despite all the hoopla to the contrary, evidence for OBL's involvement in the 9-11 attacks was lacking.
Furthermore, the director of Germany's Federal Intelligence Agency at the time of the 9-11 attacks, August Hanning, said that his agency could find no connection to "al-Qaeda terrorism."
Jason Burke, a journalist for the Manchester Guardian, went even farther and declared, in the third hour of Adam Curtis' documentary, The Power of Nightmares, that no such organization as al-Qaeda even existed, but that it was invented in order to allow charging Osama bin Laden under the USA's RICO statute. There are also scholars who have been saying that no such organization as al-Qaeda was supposed to be existed.
