Illinois Criminal Code of 1961

Article 29D: Other Offenses Related to Terrorism

There are several other crimes listed under Illinois Criminal Law that relate to terrorism. The first, causing a catastrophe, may be prosecuted when someone knowingly causes a catastrophe by explosion, fire, flood, or other means. In order for charges to be brought, at leave five people must have experienced serious injury as a result of the defendants actions. A violation of this law is a Class X felony.

This section also prohibits anyone from possessing a deadly substance. Anyone who possesses, manufactures, or transports any dangerous substance with the intent to commit a felony could find themselves facing criminal prosecution. If convicted, a defendant must serve a prison sentence no less than four years but no greater than 30 years.

There are several other crimes listed in this portion of Article 29D specifically relating to acts of terrorism. For instance, it is illegal to make a terrorist threat, even if it is false. Depending on the nature of the threat, a conviction is either a Class 1 or Class X felony, both very serious crimes that would likely carry a long prison term. In addition, it is unlawful to knowingly provide material support for terrorism as well as hinder a terrorism prosecution. Specific details regarding may be seen below in the text of Article 29D of the Illinois Criminal Code.
