See (720 ILCS 5/24-1) (from Ch. 38, par. 24-1) and consult an experienced criminal defense lawyer. The application of a statute is not a simple exercise but rather a complex legal analysis that includes the statute, the legislative history and intent, and the caselaw thst may limit or expand the meaning of the statutory language.
