These cowardly turds are domestic terrorists and should be labeled and treated as such.
Section 802 of the USA PATRIOT Act (Pub. L. No. 107-52) expanded the definition of terrorism to cover “domestic,” as opposed to international, terrorism. A person engages in domestic terrorism if they do an act “dangerous to human life” that is a violation of the criminal laws of a state or the United States, if the act appears to be intended to: (i) intimidate or coerce a civilian population; (ii) influence the policy of a government by intimidation or coercion; or (iii) to affect the conduct of a government by mass destruction, assassination or kidnapping.
