Abstract

Five events during the fall of 2009 thrust concerns over “homegrown” terrorism—or extremist violence perpetrated by U.S. legal residents and citizens1—into public view: September 19: Najibullah Zazi, an Afghan ci ■■ tizen and U.S. legal resident, was arrested on charges of conspiracy to use weapons of mass destruction. Zazi later admitted to traveling to Pakistan to receive explosives and weapons training and to planning an attack in the United States. ■■ October 27: Federal authorities charged U.S. citizen David Coleman Headley with planning to attack a Danish newspaper. In December, revelations surfaced that Headley may have conspired with operatives of Lashkar-e-Taiba, a Pakistani terrorist group, in the 2008 Mumbai attacks. ■■ November 5: Major Nidal Malik Hasan, U.S. Army, allegedly killed 13 and wounded 30 at Fort Hood Army Base, outside Killeen, Texas. Early reports revealed that Hasan had previously communicated with a radical Yemeni cleric connected to al Qaeda. ■■ November 23: Federal officials unsealed indictments against eight people charged in connection with the alleged recruitment of approximately two dozen Somali Americans to fight with an insurgent group in Somalia. ■■ December 9: Five young Northern Virginia men were arrested in Sargodha, Pakistan. U.S. and Pakistani authorities claim that the group traveled there to fight alongside Taliban militants in Afghanistan.
