Making terrorist threats is a serious crime that can lead to significant terms of custody. This is particularly true in this age of international terrorism, which has the capability of harming thousands of people. The global definitions hold sway. Interestingly, the law is rarely used in Chicago, not least because the controls put in place make it difficult for people who are that way inclined to hurt the rest of the population. There are instances in which the law has been used to suppress free speech and protest. For example; there was some public outcry when people who had been protesting against NATO were prosecuted. Other defense attorneys have argued that the law may be written in such a vague way that it opens the way for eventual abuse.
This is a law of which the public at large is critical. Terrorism causes terror and that is the beginning point of the prosecution. This criterion is also being modified in order to reflect the realities of a crime that is still in its development stages. For example, a threat made in jest whilst on a plane is bound to cause significant stress nonetheless. Therefore, the prosecutor will be given leeway to prosecute based on the reasonable expectations and anticipations of the people that are on the airplane. Indeed, it would be advisable not to make any threats at all because they could fall under other criminal laws.
