Future 9/11 hijacker Ahmed Alnami apparently attempts to purchase a gun at a US gun show. According to a 2002 FBI document about the 9/11 attacks, an unnamed person later tells the FBI that he is at a gun show in Fort Lauderdale, Florida, as a customer. But while waiting for his daughter to come out of the bathroom, a man resembling Alnami approaches him and asks how to purchase a gun without paperwork or having to wait. The person tells Alnami that it is not possible, but Alnami asserts that he understands that it is. Apparently, this is the extent of their interaction, and it is not known if this person is in fact Alnami, or if he manages to later successfully buy a gun. [Federal Bureau of Investigation, 4/19/2002] There will later be some disputed claims that a gun is used by the hijackers in the 9/11 attacks (see 9:27 a.m. September 11, 2001).
