Not all theft-related crimes are created equal. At the most basic level, when a person takes something from another person without his or her permission with the intention to not return it, they can be charged with theft. There are several other ways by which a person can commit a theft in Illinois. If a person does certain other things in addition to simply taking something or trying to take something, they can be charged with either robbery or burglary. For some people, the difference between robbery and burglary may not be clear.
