Threat

A threat is a communicated intent to inflict harm or loss on another person. A threat is considered an act of coercion. Threats (intimidation) are widely observed in animal behavior, particularly in a ritualized form, chiefly in order to avoid the unnecessary physical violence that can lead to physical damage or death of both conflicting parties.

Some of the more common types of threats forbidden by law are those made with an intent to obtain a monetary advantage or to compel a person to act against his or her will. In all US states, it is an offense to threaten to (1) use a deadly weapon on another person; (2) injure another's person or property; or (3) injure another's reputation.

Brazil

In Brazil, the crime of threatening someone, defined as a threat to cause unjust and grave harm, is punishable by a fine or three months to one year in prison, as described in the Brazilian Penal Code, article 147. Brazilian jurisprudence does not treat as a crime a threat that was proffered in a heated discussion.
