do u think there is a contribution of BINLADEN in 9/11

I found this in Wikipedia: Bin Laden initially denied, but later admitted involvement in the incidents. On September 16, 2001, bin Laden denied any involvement with the attacks by reading a statement which was broadcast by Qatar's Al Jazeera satellite channel: "I stress that I have not carried out this act, which appears to have been carried out by individuals with their own motivation." This denial was broadcast on U.S. news networks and worldwide. In November 2001, U.S. forces recovered a videotape from a destroyed house in Jalalabad, Afghanistan, in which Osama bin Laden is talking to Khaled al-Harbi. In the tape bin Laden admits foreknowledge of the attacks. The tape was broadcast on various news networks from December 13, 2001. On December 27, 2001, a second bin Laden video was released. In the video he stated "Terrorism against America deserves to be praised because it was a response to injustice, aimed at forcing America to stop its support for Israel, which kills our people," but he stopped short of admitting responsibility for the attacks. Shortly before the U.S. presidential election in 2004 in a taped statement, bin Laden publicly acknowledged al-Qaeda's involvement in the attacks on the U.S, and admitted his direct link to the attacks. He said that the attacks were carried out because, "We are a free people who do not accept injustice, and we want to regain the freedom of our nation." In a videotape aired on Al Jazeera on October 30, 2004, bin Laden said he had personally directed the 19 hijackers. Another video obtained by Al Jazeera in September 2006 shows Osama bin Laden with Ramzi Binalshibh, as well as two hijackers, Hamza al-Ghamdi and Wail al-Shehri, as they make preparations for the attacks.
