2004 -- Bin Laden's Admission
In October 2004, a video of bin Laden airs on Arabic television. In the taped message, al-Qaida's leader, who had for years denied his involvement in the September 11 attacks, finally confesses that he played a lead role in the plot. The United States continues to offer a $25 million bounty to anyone who helps them catch or kill bin Laden. In spite of the unprecedented reward, al-Qaida's leader continues to evade detection for years.
