Texas[edit]
In Texas, terroristic threats are prohibited under Chapter 22 of the Penal Code:[2][3]
Sec. 22.07. TERRORISTIC THREAT. (a) A person commits an offense if he threatens to commit any offense involving violence to any person or property with intent to:
(1) cause a reaction of any type to his threat by an official or volunteer agency organized to deal with emergencies;(2) place any person in fear of imminent serious bodily injury;(3) prevent or interrupt the occupation or use of a building, room, place of assembly, place to which the public has access, place of employment or occupation, aircraft, automobile, or other form of conveyance, or other public place;(4) cause impairment or interruption of public communications, public transportation, public water, gas, or power supply or other public service;(5) place the public or a substantial group of the public in fear of serious bodily injury; or(6) influence the conduct or activities of a branch or agency of the federal government, the state, or a political subdivision of the state.
A federal-level law in the United States prohibits threatening terrorism against the United States.
