One of the defining features of terrorist acts has always been a component of violence. Even under the expanded definition of terrorism created by the USA PATRIOT Act, there must be an act that is “dangerous to human life” indicating some form of physical harm to others could arise from the action. However, the Homeland Security Act of 2002, which created the Department of Homeland Security, extended the definition of terrorism further by including any act that is “damaging to critical infrastructure or key resources.” Though this definition differs from the legal definition of international and domestic terrorism under 18 USC § 2331, the modified definition is currently used by DHS as the basis for their own activities and intelligence products that are disseminated to federal, state and local law enforcement. The modified definition of terrorism is presented in a revised Domestic Terrorism and Homegrown Violent Extremism Lexicon published last year by DHS:

Any activity that involves an act that is dangerous to human life or potentially destructive to critical infrastructure or key resources, and is a violation of the criminal laws of the United States or of any state or other subdivision of the United States and appears to be intended to intimidate or coerce a civilian population to influence the policy of a government by intimidation or coercion, or to affect the conduct of a government by mass destruction, assassination, or kidnapping.

Notice that the statement “potentially destructive to critical infrastructure or key resources” is part of a disjunction, indicating that the act need not be “dangerous to human life” for it to be considered an act of terrorism. This means that, according to DHS, a non-violent actor could be capable of committing an act of terrorism simply by engaging in “potentially destructive” behavior towards some part of the nation’s critical infrastructure. Due to the fact that large sections of domestic infrastructure, including everything from banks to bridges to milk processing plants, are now considered critical infrastructure, a wide range of “potentially destructive” actions could be investigated by DHS or any one of the dozens of fusion centers around the country as potential acts of terrorism. The DHS Domestic Terrorism Lexicon states that the definitions presented in the document are designed to “assist federal, state, and local government officials with the mission to detect, identify, and understand threats of terrorism against the United States by facilitating a common understanding of the terms and definitions that describe terrorist threats to the United States.”
