I thought you were one of those who claimed that financial power and wealth was a paramount goal of this conspiracy?
Right, I had forgotten about that. In his first public statement just 5 days after the attacks, he claimed he didn't do it. It's possible he was buying some time to dig in somewhere. Anyways, there's plenty of other transcripts of his where he does take credit and spells out how and why, on that same wiki page.
On November 9, 2001, U.S. military forces in Jalalabad found a video tape of bin Laden.
On December 13, 2001, the United States State Department released a video tape apparently showing bin Laden speaking with Khaled al-Harbi and other associates, somewhere in Afghanistan, before the U.S. invasion had driven the Taliban regime from Kandahar. The State Department stated that the tape was captured by U.S. forces in Afghanistan during a raid on a house in Jalalabad. The tape was aired with an accompanying  English translation. In this translation, Osama bin Laden displays knowledge of the timing of the actual attack a few days in advance;
Some members of Scholars for 9/11 Truth believe that the man in this videotape is not Osama bin Laden at all, citing differences in weight and facial features, along with his wearing of a gold ring, which is forbidden by Muslim law, and writing with his right hand although bin Laden is left-handed. Andy Laws, a former military imaging analyst for the Royal Air Force, says the fact that bin Laden appears fatter in the 2001 tape is down to the editing process, when subtitles were added and the image was squashed.
Well, there's probably other tenants of the Islamic faith that he violated, beside wearing a gold ring. For example his stash of porn. Anyways, for arguments sake let's you are right, that's not OBL in that video. Fine. I will tag this video/transcript for further examination of it's content and provenance
But you can't claim that since U.S. officials lied in the past about certain events, they must necessarily be lying now about 911. You may feel strongly about this, but you can't use it in a reasoned argument.
