On Friday, November 16, 2012, Adis Medunjanin was sentenced to life in federal prison for his involvement in a plot to bomb the Manhattan subway system in New York City on the eighth anniversary of the 9/11 attacks.1
That plot, masterminded by Najibullah Zazi and involving a third conspirator, Zarein Ahmedzay, represents the only known al Qaeda–directed plot on U.S. soil since 9/11. The investigation that uncovered and disrupted it was a masterpiece of cooperative efforts at the federal, state, and local levels. It demonstrates how far we have come since the days prior to 9/11.
