The emphasis of counterterrorism policy in the United States since Al Qaeda's attacks of September 11, 2001 (9/11) has been on jihadist terrorism. However, in the last decade, domestic terrorists-people who commit crimes within the homeland and draw inspiration from U.S.-based extremist ideologies and movements-have killed American citizens and damaged property across the country. Not all of these criminals have been prosecuted under terrorism statutes. This latter point is not meant to imply that domestic terrorists should be taken any less seriously than other terrorists.
