Based on the 9/11 Commission hearing on January 26, 2004, the commission staff issued a statement discussing missed opportunities in averting 9/11: “Every time a hijacker offered up a doctored passport, made a false statement on a visa application or in an interview, or violated an immigration law, there was an opportunity to foil the plot, or at least to remove one of the potential perpetrators. We missed nearly all of those opportunities.”
