If I'm correct, that applies to an intruder in your home. Not someone in walmart.
TITLE 21 § 1289.25. Physical or deadly force against intruder
D. A person who is not engaged in an unlawful activity and who is attacked in any other place where he or she has a right to be has no duty to retreat and has the right to stand his or her ground and meet force with force, including deadly force, if he or she reasonably believes it is necessary to do so to prevent death or great bodily harm to himself or herself or another or to prevent the commission of a forcible felony.
It seems that a lot of people get hung up on the "fear of death or imminent death" and overlook the fact that deadly force can be used to prevent a forcible felony. Kidnapping is considered a forcible felony, so deadly force would be justified. Not a dumb question, by the way.
P.S. I am not a lawyer, don't play one on TV, and I did not stay at a Holiday Inn Express last night.
