Khalid Shaikh Mohammed, suspected mastermind of the September 11, 2001 terror attacks in the United States, is arrested in Pakistan. As a member of Osama bin Laden's al-Qaeda terrorist organization, he directed their propaganda efforts since 1999.
U.S. agents will repeatedly waterboard Khalid Shaikh Mohammed for information, leading to him confessing to being behind the 9/11 terror attacks against the World Trade Center in New York City, the 1993 World Trade Center bombing, the Richard Reid shoe bombing attempt, the Bali nightclub bombing, and various other incidents.
Whether any of this is true or not is a matter of some debate, since under torture people will confess to anything in order to get the torture to stop.
Khalid Shaikh Mohammed will be charged with war crimes, but because of the means by which information is extracted and perhaps even his alleged mental state following years of torture, it's questionable whether he will ever be able to see a courtroom.
