It is a Class B Misdemeanor to threaten to commit a crime of bodily injury, death or serious property damage. Up to six months in the Utah county jail and a fine. Plus you may have to reimburse the local government for having to respond to the incident unless you can persuade the judge otherwise. That’s called criminal restitution. See this deeper article on restitution here.
Utah’s Threat of Violence crime has the following elements that the city or county prosecutor’s must prove beyond a reasonable doubt:
1. You threaten to commit a criminal offense involving
a. Bodily injury, or
b. Death, or
c. Substantial property damage, AND
2. You act with intent to put that person (or someone else) in fear of imminent serious bodily injury, substantial bodily injury or death, OR
The prosecutor cannot only charge you for mere words spoken, but can also stack your threat of violence charge on top of other charges. Common charges stacked with a threat of violence charge is domestic violence, disorderly conduct or assault and battery. Nothing precludes stacking threat of violence with other crimes.
