A person is justified in using or threatening to use deadly force only if the person reasonably believes that the use of deadly force is necessary to prevent the imminent commission of a forcible felony.
A person who uses or threatens to use deadly force in accordance with this section does not have a duty to retreat and has the right to stand his or her ground, if the person using or threatening to use the deadly force is not engaged in a criminal activity and is in a place where the person has a right to be.
