The 9/11 Commission Report concluded that the prosecutions of the 1993 World Trade Center bombing conspirators created a false impression that the U.S. criminal justice system was “well-equipped to cope with terrorism”:
As a result of the investigations and arrests, the U.S. Attorney for the Southern District of New York prosecuted and convicted multiple individuals, including Ajaj, Salameh, Ayyad, Abouhalima, the Blind Sheikh, and Ramzi Yousef, for crimes related to the World Trade Center bombing and other plots. An unfortunate consequence of this superb investigative and prosecutorial effort was that it created an impression that the law enforcement system was well-equipped to cope with terrorism. Neither President Clinton, his principal advisers, the Congress, nor the news media felt prompted, until later, to press the question of whether the procedures that put the Blind Sheikh and Ramzi Yousef behind bars would really protect Americans against the new virus of which these individuals were just the first symptoms.
Unfortunately, it appears as though the Obama administration prefers to learn this lesson on its own.
