false.

Explanation:

A threat is an intimidation and can be considered an offense, resulting in legal penalties for the perpetrator.  That is, the threat of violence can already be considered a crime, even if the act of violence itself has not been performed, provided that this threat is made in an unfair and / or serious manner that offends the victim or generates fear. . For this reason, we can say that there are punishments that can be made for those who proclaimed a threat of violence, even if the act of violence did not actually occur.
