Stand Your Ground Law in Illinois. According to US self-defense legislation, a person may use lethal force in public if it was required to save their life or the life of another person from impending death or serious bodily harm.
These laws have historically made it plain that if a person could have avoided employing deadly force by fleeing or just stepping away from a conflict, then taking their life is not required and, hence, not justified.
However, the Castle Doctrine states that a person is not required to leave a confrontation before using force in their house.
Maintain your position. Laws overturn centuries of legal precedent by permitting the use of fatal force in public self-defense, even when withdrawing would safely prevent the use of such force or when nonlethal force would be more appropriate.
The Law of Illinois
The Illinois Supreme Court has ruled that there is no obligation to back down before using force in public, despite the state’s lack of a stand your ground law. The use of lethal force to stop the commission of a forcible felony—which includes burglaries of empty vehicles—is permitted by Illinois law.
