Domestic terrorism is not a new phenomenon; though, law enforcement organizations appear to be facing a multifaceted domestic threat in the forms of Lone Wolf terrorism, special-interest terror groups and radicalized persons. In brief describe each of these groups, and also their present and historic motivations, providing illustrations of significant incidents in the U.S. involving each.

Finally, recognize the present structure in the U.S. to recognize potential domestic terror threats, interrupt terrorist planning cycles, and mitigate the impact of successful attacks. Be sure to address the roles of Federal, State, Local and Tribal agencies and organizations in these efforts, and also those of private industry and concerned citizens.
