A report examines 123 terrorist cases from the past 15 years, and the study's two principal authors say that the courts were able to produce just, reliable results while protecting national security.

The report comes at a time when the Bush administration's system of military commissions remains mired in delays.

Whether the case is the first attack on the World Trade Center in 1993 or the East African embassy bombings in 1998, judges, juries, defense attorneys and prosecutors are able to get the job done correctly, they say.

Although the justice system is far from perfect, it has proved to be adaptable and has successfully handled a large number of important and challenging terrorism prosecutions, said New York lawyers Richard Zabel and James Benjamin of the law firm Akin Gump Strauss Hauer & Feld.
