There is another type of warfare — new in its intensity, ancient in its origin — war by guerrillas, subversives, insurgents, assassins; war by ambush instead of by combat, by infiltration instead of aggression, seeking victory by eroding and exhausting the enemy instead of engaging him . . . It preys on unrest. . . .

Address to the Graduating Class,
U.S. Naval Academy, June 6, 1962

The FBI differentiates hate crimes and other criminal activity from domestic terrorism partly by assessing the intent of the criminals involved in specific incidents. Hate crimes “generally involve acts of personal malice directed at individuals” and lack the broader motivations and driving acts of domestic terrorism. In addition, the lines are not always clear between ordinary criminal acts and domestic terrorism. In these instances, FBI investigations also focus on clarifying the motives of the suspects involved—such as profit, personal malice, or an ideologically driven agenda.
