Which action is classified as making terroristic threats?

Making terroristic threats specifically involves communicating a threat to commit violence with the intent to terrorize another, to cause evacuation of a building, or to cause serious public inconvenience. Threatening to kill falls squarely within this definition as it conveys a serious intent to inflict harm and creates a sense of fear and panic in the victim and potentially in the broader community.

The other actions listed, while potentially involving threats, do not necessarily fit the legal definition of terroristic threats as clearly. Threatening to harm property may involve crime but does not inherently instill the same level of fear for personal safety. Threatening to expose secrets can involve coercion or intimidation, yet it typically doesn't entail an immediate threat to life or physical safety. Lastly, threatening physical restraint can imply a loss of freedom or safety, but it needs to be contextualized within the broader intent and implications of the threat to match the legal criteria for terroristic behavior. Thus, the action of threatening to kill is categorized as making terroristic threats due to its direct implications of violence and fear.
