"A person who is not engaged in an unlawful activity and who is attacked in another place where he has a right to be, including, but not limited to, his place of business, has no duty to retreat and has the right to stand his ground and meet force with force, including deadly force, if he reasonably believes it is necessary to prevent death or great bodily injury to himself or another person or to prevent the commission of a violent crime as defined in Section 16–1–60."
Stand Your Ground Laws are often expansions of the Castle Laws. They address the use of force outside of one's home, place of work, or vehicle. They cover most of the same issues as the castle laws (the places where this law applies, the requirements fro use of deadly force, if there is a duty to retreat, the amount of force that maybe used in defending one's self or others) the main difference is the location. Some states that do not have a technical Stand Your Ground Law have extensive Castle Laws that address locations outside of the home, place of work, etc. The circumstances of the law vary widely from state to state.
